Clearer secrets seen by drones - The role of optical lenses

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 outdoors, so that more people can experience a higher 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 point, 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 and oil stains.

Of course, drone shooting to achieve more advanced features can be coated on the optical lens with different performance of the optical film layer, for example: To achieve day and night dual-switching function, can be coated with IR-CUT filter The film parameters of the film parameters, to achieve license plate recognition camera, we can plate the film to inhibit the role of strong light.

In short, with the development of the optical lens coating level, we believe that drones can achieve more functions in shooting.
