Jianeng has always attached importance to the field of home digital cameras. In 2012, it has started to develop the security camera market in China to promote the diversified development of business. At that time, Canon China President xiaozexiushu said that in the next five years, Canon will vigorously develop the network surveillance camera market in China, strive to achieve 30% market share and become the leader in the "security" field. Canon is stepping up the development of surveillance camera business. It plans to develop the world market by combining Canon's optical technology, the image management system acquired through M & A and the image processing software. In the surveillance camera market, Chinese enterprises have expanded their shipments with low-cost products, on the other hand, they are also affected by the Sino US trade war. Canon will seize the opportunity to challenge two major Surveillance Camera Companies in the world in the field of good camera business. According to the Chinese daily news network, the image of 2 megapixel camera produced by axex network communication company in Sweden is analyzed through the "crowd counting" technology of canon. The technology can count the number of people concentrated in specific areas of the venue in an instant, which can be used to ensure the safety of the audience. In late April, at the factory opening ceremony in Miyazaki County, Mr. Canon President Yushou Fujifu said, "although the market of digital cameras has shrunk, it still has a broad market in terms of optical industry.". The company produces a variety of lenses at Miyazaki's factory. In Japan, the cameras will be sent to Nagasaki county factories and assembled into the final product of surveillance cameras. Canon did not publicly monitor the performance of the camera business alone, but revenue from January to June 2019 increased by 10% year-on-year, and it is expected that the revenue will also increase throughout t

After the outbreak of New Coronavirus pneumonia, body temperature measurement has become the first pass of epidemic detection. Because of its non-contact, high efficiency, easy to use characteristics, infrared temperature detector is widely used in the crowded traffic gates, stations, airports, hospitals, residential areas, enterprises and institutions, and has been included in the key materials of epidemic prevention and control by the State Council. 1.png Infrared temperature detector used in many occasions 1. What is an infrared thermometer Any object with temperature higher than absolute zero (0 K or - 273.15 ℃) will emit electromagnetic radiation from the surface, and the radiation is proportional to the inherent temperature of the object. In this kind of radiation, infrared radiation for temperature measurement is included. When the radiation passes through the atmosphere, it can be concentrated on the detector with the help of a special lens. 1.jpg The detector then generates an electrical signal proportional to the radiation. The signal is amplified and transformed into an output signal proportional to the temperature of the object through continuous digital signal processing. In this way, the temperature measurement value will be displayed on the display, and the color image which is easy to identify will be output. This is the working principle of the external thermal imaging thermometer. Dynamic thermography.gif The commonly used infrared temperature detectors can be divided into two types: infrared thermal imaging temperature rapid screening instrument and infrared thermometer (infrared ear thermometer and infrared forehead thermometer, etc.). For residential and commercial super scenes, infrared thermometer or hand-held infrared thermal imaging thermometer can basically meet the needs. The infrared thermometer has the advantages of simple equipment, convenient use and affordable price, whi

With the development of laser application in industry, the demand for higher power and shorter wavelength is gradually extended. As the core of laser application, the improvement of fiber laser technology is particularly important. Domestic fiber lasers are gradually developing in the direction of higher power, smaller volume and more stable operation. However, most of the ten thousand watt lasers on the market are multi-mode lasers. These products are often large in size, with many accessories and many hidden troubles. Therefore, improving the output power of single laser module and optimizing the structure of the whole machine become the key to further optimize the laser performance. At present, there are many domestic manufacturers of 10000 watt lasers, but in terms of 100000 watt level, especially single module laser manufacturers are few. On March 17, at the grand banquet of optoelectronic technology industry at Shanghai Munich optical Expo, the domestic 100000 watt laser devices made a lot of eyes, and of course showed the domestic muscles. Let's have a look. 1. Big family laser 20000 watt fiber laser released The new product launch of Han's laser Intelligent Equipment Group officially released Han's laser 20kW ultra high power fiber laser, attracting many industry experts, customers and media celebrities to witness and praise. Through top-level strategic layout and system planning, Han's laser has obtained more than 100 patent technologies, including upstream optical material research, pump source packaging, core optical fiber device development, midstream complete machine research and development, mass production and manufacturing, and downstream high-power application solutions. In 2020, more than 100 sets of Han's 10000 watt photonic fiber lasers will be sold and applied in the market. 2. Ruike laser released a single module 12KW laser on site and demonstrated the light cutting on site Ruike laser released a single

Optical ball cover is mainly used to protect the application of precision instruments, equipment and cameras in harsh environment. In addition to the common and low cost optical glass ball cover, Berna can also produce high-precision quartz glass ball cover. The common fused quartz glass is divided into ultraviolet quartz glass and infrared quartz glass. The UV quartz glass has a relatively good transmittance at 190nm-2650nm, but it will be absorbed at 2200nm and 2650nm. The infrared quartz glass has a good optical transmittance at 280nm-3800nm. If the target is protected and applied to the ultraviolet band, the UV quartz glass is a better choice. It is assumed that the infrared quartz glass will be more suitable for the infrared band. At the same time, compared with the common optical glass h-k9l, n-bk7, the mechanical strength and chemical properties of quartz glass are better, but the price of its wool blank is far higher than that of the common optical glass.

In a broad sense, aspheric surface is other surface which does not include spherical surface and plane surface. From the perspective of application, aspheric surface can be divided into axisymmetric aspheric surface, aspheric surface with two symmetrical planes and free-form surface without symmetry. Aspheric surface classification Aspheric surface is usually divided into quadratic aspheric surface and higher aspheric surface. Quadratic aspheric surface is the most widely used in optical system, which has a special position compared with other types of aspheric surface. Quadratic aspheric surface can be divided into two parts: aspheric surface with a pair of non image handicaps and aspheric surface without non image handicaps. The former is widely used in various optical instruments and is the most common aspheric surface. The latter is widely used in optical systems to form distorted images. The aspheric surface of higher degree can be divided into the surface of monotone meridian curve and non monotone surface. The classification of aspheric surfaces is shown in Figure 1. Figure 1. Classification of optical aspheric surfaces free-form surface The general expression of free-form surface: z = ∑ AIJ xiyj I, j = 0,1,2... N. For this kind of free-form surface, although it has lost the characteristic of aspheric axis symmetry, it is still around a coordinate origin. Now there are rules to follow. Another kind of complex free-form surface, which can only be defined by three-dimensional point coordinates, is widely used in progressive multifocal glasses to achieve the purpose of power distribution according to a specific law. Advantages and application of aspheric surface Aspheric lens, the radius of curvature changes with the central axis, to improve the optical quality, reduce the optical components, reduce the design cost. Compared with spherical lens, aspheric lens has unique advantages, so it has been widely

The Japan Camera Imaging Equipment Industry Association predicts that the global digital camera shipment may drop by 20% in 2019 to about 15 million units, only about one eighth of the peak in 2010. The performance of digital camera enterprises is not optimistic due to the extrusion of smart phones with improved camera performance. At present, the proportion of smart phones equipped with multiple cameras has reached 70%, and it is expected to reach more than 90% in 2023. Or the lowest level since 2001 (14.75 million units). According to the report, the global shipment volume in the first 10 months of 2019 was 12.73 million units, a decrease of 20%, while the annual shipment volume may drop to about 15 million units, only about one eighth of the peak in 2010 (121.46 million units), or the lowest level since 2001 (14.75 million units). The performance of digital camera enterprises is not optimistic due to the extrusion of smart phones with improved camera performance. Olympus will raise the price of replaceable lens by about 10%, Nikon will reduce the business cost by 50 billion yen, and the sales of digital cameras still show no sign of recovery. It is reported that the ratio of smart phones equipped with multiple lenses has now reached 70%, and it will increase to more than 90% by 2023. And due to the continuous improvement of smart phone camera components and system optimization, it is more convenient to use than digital cameras, which must be another reason for the decline of digital camera sales. Supply of digital cameras in 2018: in Japan, the supply itself decreased, but the supply of non reflective cameras increased, surpassing that of SLR cameras for the first time. Global supply decreased by 22.2% to 19.42 million units. In particular, the number of card machines decreased by 34.9% to 8.66 million, a significant decrease. In Japan, the number of non reflective cameras increased by 8.6% over the previous year to 590000, surp

The photoelectric and intelligent manufacturing equipment industry is listed as a strategic emerging industry by the state, provincial and municipal governments. Based on Changchun's strong photoelectric industry and equipment manufacturing industry, the principle of "government oriented, enterprise led and market-oriented operation" is adopted. The photoelectric and intelligent equipment Industrial Park in Changchun new area should be born at a time. Changchun new area photoelectric and intelligent equipment industrial park is a precision instrument and intelligent equipment manufacturing industry cluster built by Changchun New Area in combination with Changchun Bureau of industry and information technology and Changchun optical machinery of Chinese Academy of Sciences. The industrial park is supported by advanced manufacturing industry and led by strategic emerging industries to create a high-end intelligent industrial belt in Northeast Asia. As a key park for the development of intelligent equipment manufacturing industry in Changchun new area, Changchun photoelectric and intelligent manufacturing industrial park has achieved a qualitative leap in 4 years. A number of small giant enterprises and high-tech enterprises with high technology content and good growth have been cultivated. In 2020, the second phase high-quality industrialization project of 12 parks represented by Yongli laser, Huibang technology, jemin photoelectric, and oto Automation Co., Ltd. will be fully commenced. In 2022, phase I and phase II projects of the park will be completed and put into operation, and the output value is expected to exceed 5billion yuan. The planned area of photoelectric and intelligent manufacturing industrial park is 1million square meters, with a total investment of 2.4 billion yuan. 34 enterprises have been introduced in 2018, 18 of which are high New technology enterprises, 4 provincial technology research centers and 3 listed companies on the thi

Not long ago, the national major scientific research and equipment development project "4m level high precision silicon carbide aspheric mirror integrated manufacturing system" undertaken by Changchun Institute of Optics and machinery passed the project acceptance. This is the largest single SiC mirror in the world. The achievement also marks that China's optical system manufacturing capacity has reached the international advanced level, and has laid a solid foundation for the leapfrog upgrading of China's large-diameter optoelectronic equipment. The 4-meter-diameter, 1.6-ton "big mirror" is like a huge circular disk - if it is installed in a telescope, its resolution will be greatly improved. "Modern large aperture optical systems all adopt reflective structure, in which the aperture of the primary mirror directly determines the resolution of the system. The larger the aperture, the higher the resolution and accuracy of the optical telescope." Jiang Huilin, a project acceptance expert of 4-meter silicon carbide mirror and academician of Chinese Academy of engineering, said. It is not easy to build large aperture mirrors[ The upper limit of mirror diameter depends on the manufacturing capacity. At the same time, in order to ensure the resolution and imaging quality of the telescope, the mirror must have a very high surface accuracy. " Zhang Xuejun, deputy director of Changchun Institute of Optics and mechanics, said that taking the visible light band observation as an example, the surface accuracy is required to be at least 1 / 30 of the wavelength, which is like magnifying a 4-meter mirror to the size of a city for land leveling, and requiring the height difference between the southeast corner and the northwest corner to be within a few millimeters of plus or minus zero, and the land flatness to be less than 1 mm. This puts forward very strict requirements for mirror blank materials and optical processing technology. For the

On March 2, we learned from the Department of precision instruments of Tsinghua University that Professor Zhang Shulian's research group of the Department has carried out the principle research, and the birefringence dual frequency laser interferometer developed and produced by Beijing radium Measurement Technology Co., Ltd. has realized mass production. Dual frequency (two frequency) laser interferometer is an optical ruler for scientific research, lithography, CNC machine tools, aerospace, ships and other industries. It is used to measure the size, angle, position and linearity of parts. It is also a basic instrument for verifying the accuracy of various CNC machine tools, laser processing machine tools and lithography machines and for error compensation. Zhang Shulian introduced that dual frequency laser is the core component of dual frequency laser interferometer. Foreign interferometer manufacturers are self-made special laser, known as Zeeman dual frequency laser, not for external supply. In the past, China's dual frequency laser interferometer could only import ordinary lasers, from which the usable ones were selected, with high elimination rate and poor performance, leading to difficulties in localization of dual frequency laser interferometer. According to reports, the birefringent dual frequency laser invented by the Department of precision instruments of Tsinghua University is twice as high as the traditional Zeeman dual frequency laser in laser power, twice or three times as large in frequency interval, and there is no coupling and mixing between two frequencies. The resolution is 1 nm (billionth of a meter), the linear measurement length ranges from 0 to 70 meters, the nonlinear error is less than 1 nm, and the measurement speed is more than 2 meters. Zhang Shulian pointed out that the use of birefringent dual frequency laser has led to the innovative design of the optical mechanical and electrical system of the interferomete

To boost U.S. manufacturing capacity and promote innovation, on Wednesday, the U.S. Congress announced the establishment of an optics and photonics caucus. The group aims to develop optical based technology in the United States by increasing public or private investment and increasing the number of skilled optical technicians. "The purpose of [the group] is to ensure that our country remains ahead of the rest of the world in fundamental optical technology innovation," said US congressman Joe morelle, founder of the core group on optics and photonics. It's no exaggeration to say that [optics and photonics] light up our future It is reported that Joe morelle's constituency includes Rochester, an important optical town in the United States, where the world-famous optical companies Kodak and Bausch & Lomb are located. At present, the US Department of defense and the national photonics program are optimistic about the establishment of the optics and photonics core group. Ed white, chairman of the national photonics program of the United States, pointed out that the field of Optics and photonics is closely related to semiconductors, and the manufacturing and packaging processes of photonic integrated circuits are consistent with those of semiconductor integrated circuits. Therefore, the society of Optics and photonics benefits from the rapid development of current semiconductor technology. Ed white predicts that all-optical processors may be available in the next 20 to 30 years, based on the current progress in the design and performance of CPUs. In addition, the U.S. Department of defense also supports photonics technology innovation and expanding the manufacturing scale of the optical industry. In November 2020, the Pentagon released the national imperative for industrial skills program, which includes the establishment of a precision optics alliance to promote the technology, This may be because the United States

Material division: The milling, turning and polishing are the representative, mainly including traditional milling and polishing; CNC milling, turning, precision grinding and polishing; Computer controlled polishing, etc. Especially for NC Polishing, the polishing medium can be divided into small grinding tools, stress plates, ion beams, plasma, magnetorheological, liquid jet polishing, etc. The characteristics of the method are that the efficiency is relatively high, the interoperability with traditional optical processing is easy to accept, the flexibility is high, and it is suitable for the development of sample and small and medium-sized batch production. But the product consistency is poor, and the requirements for operators are higher. Die forming method: Glass hot pressing, optical plastic injection molding, thermal settlement and solidification forming. The characteristics of the product are high efficiency, good consistency of finished products, low requirements for operators, and suitable for mass production. But the requirements of the mould are high, the initial investment is large and the process flow is more complex. Additional material method (adding material method): Vacuum coating and copying. The essence of the material is to add a layer of thin layer material which matches the asphericity and refractive index on the basis of the closest to the sphere. The features of the work piece are good consistency, low requirements for equipment and good flexibility. It is suitable for the production of small and medium-sized and reflective elements. However, the application is limited by the matching of additional layer with the base material. Aspheric processing method and equipment 1.JRCODE-CCOS The main body of the machine is gantry structure. The moving parts are equipped with precise guide rail and high precision grating feedback. The 8-axis controller is used to realize the combination inte

Introduction: During the shooting of daily drones, many users will find a problem. When our drones are used for a period of time, the images taken are not clear enough to have a vague feeling. In fact, this phenomenon is the result of the degradation of the optical film performance of the drone camera lens. In recent years, the development of the drone market is changing with each passing day, and more and more people like to buy drones as a tourist to go out and play outdoor shooting, so that more people can experience a higher and more distant and clearer visual experience. In the shooting of daily drones, many users will find a problem. When our drones are used for a period of time, the images taken are not clear and fuzzy. In fact, this phenomenon is the result of the degradation of the optical film performance of the drone camera lens. It also shows the effect of the quality of optical filters on long-term stability. There will be an optical lens glass in front of the UAV CMOS imaging chip. At the design site, the manufacturer will be coated with an anti-reflection film (also known as AR anti-reflection filter). The role of this film is mainly The role is to enable the optical components to reduce the loss of light energy due to reflection, thereby increasing the transmitted light intensity of the coating, the transmittance of more than 90%, the reflectance of less than 2% of the glass. The characteristics of the reflection will be more clear when the drone is photographed, and the drone's optical lens is coated with professional films such as AS film to prevent water stains and oil stains. Of course, drone shooting to achieve more advanced features can be coated on the optical lens with more different optical film layer

According to the National Space Administration, at 11:10 on July 3, 2020, China successfully launched a high-resolution multimode integrated imaging satellite with the long march 4B carrier rocket at the Taiyuan Satellite Launch Center. The launched high-resolution multi-mode integrated imaging satellite was developed by the Fifth Academy of China Aerospace Science and Technology Group Co., Ltd. High resolution multimode integrated imaging satellite is the first optical remote sensing satellite with sub meter resolution and multiple agile imaging modes in China. It will be mainly used to obtain high-resolution images of China's territory and surrounding areas. This is a civil optical remote sensing satellite with sub meter resolution, which can switch multiple imaging modes. Its on orbit application will further improve the technical level of remote sensing satellite in China, and meet the needs of relevant industry user departments for high-precision remote sensing image data. Satellites mainly serve natural resources, disaster reduction and emergency response, agriculture and rural areas, ecological environment, housing construction, forestry, grassland and other industries, which will break the monopoly of international commercial remote sensing satellite companies on the sub meter resolution remote sensing image market. High resolution multi-mode satellite is the highest resolution optical remote sensing satellite in the national medium and long term development plan for civil space infrastructure (2015-2025). It was established in 2018 and implemented in PPP mode. The satellite uses the public platform of medium-sized agile remote sensing satellite, which is equipped with high-resolution camera, atmospheric synchro corrector and other business loads, as well as laser communication terminal test load, and runs in the sun synchronous orbit. During on orbit operation, the high resolution multi-mode satellite will verify agile maneuver c

1 nanometer is one-eighth of a hair, and less than 1 nanometer is called sub-nanometer-this is the "Chinese precision" created by the National Defense University Precision Engineering Innovation Team in the processing of ultra-precision optical parts, which is strongly supported Innovative breakthroughs in major national science and technology projects such as "Very Large Scale Integrated Circuit Manufacturing Equipment and Complete Processes" and other three countries have created direct economic benefits of more than 200 million yuan for the country in the past three years. Recently, the school developed two types of super-precision polishing equipment that passed the national major scientific and technological special acceptance. Ultra-precision machining is an advanced manufacturing technology with the goal of high precision. Nano-precision is known as the crown jewel of ultra-precision machining technology. Western developed countries regard it as a strategic resource and strictly restrict exports. Facing the dilemma of China's optical component manufacturing level, the National Defense University Precision Engineering Innovation Team, led by Professor Li Shengyi, skipped the first and second generation optical component manufacturing processing technology and directly aimed at the third generation optical processing method based on controllable flexible body manufacturing To solve problems, for the first time in China, we developed two kinds of super-precision polishing equipment with independent intellectual property rights, such as magnetorheological and ion beam, which created the miracle of "Chinese precision" in

According to the Department of science and technology of Tibet Autonomous Region, the project of "construction of one meter optical astronomical telescope with dual functions of scientific research and popular science in high altitude areas" jointly declared by the National Astronomical Observatory of the Chinese Academy of Sciences and the Tibet Museum of natural sciences has officially started a few days ago, which means that the world's largest refracting optical telescope will land in Lhasa. Wang Junjie, deputy director of the science and Technology Department of the Tibet Autonomous Region, said that the one meter optical telescope will be independently developed and built by Chinese scientists. After completion, with Tibet's high altitude and good observation conditions, it will be able to carry out a number of scientific research and observation work, such as poor photometry of variable stars, binary stars and other celestial bodies, monitoring of near Earth Asteroids and space targets. At the same time, it will also provide in-depth services for popular science education in Tibet.

The rare-earth metal element yttrium may not be known by ordinary people. This gray metal has a density of 4.4689 g/cm3, a melting point of 1522C, a boiling point of 3338C, and a valence of +3. The first ionization energy is 6.38 electron volts, which reacts with hot water and is easily soluble in dilute acids. Its main purpose is to be applied to optical instrument lenses and secondary batteries. However, for the Japanese island nation, rare earth elements are very scarce, and most rely on imports from China. However, this situation may be broken now because Japanese researchers at Kyushu University discovered for the first time in Japan two new minerals that contain rare earth element tellurium. These two kinds of new minerals containing rare earth niobium were found in basalt collected at the Dongmuppu Peninsula (Dangjin City and other places) in the northwest of Saga Prefecture. The analysis was conducted through a microscope and X-ray, and it was finally confirmed that this was not discovered. New ore. Therefore, researchers believe that there may be deposits on the East Matsuura Peninsula. Japan submitted an application to the International Mineralogy Association IMA in March of this year. The two new ores are named [Rhodium Phosphorus Rare-Earth Mine" and [Fertile Front Stone" respectively. At pres
