Elliptical broadband mirror optical
Flat mirrors are optical
mirrors that are used for applications that deflect light as accurately as
possible, including interferometry, beam steering or folding, or as optical
elements in the imaging systems, such as astronomical telescopes in space station.
Bena offers various flat mirrors, including standard or high...
Plano mirrors What is Plano (Flat) mirrors Plano (Flat) mirrors are Optical Mirrors designed for a variety of applications, with a flat reflection surface. If an optical system can form a perfect image with random wide beam in any large space, namely, any concentric beam can still be kept as a concentric beam after...
Double concave lens is similar to flat concave lens. The focal length is negative, but the light incident in parallel diverges outward. The curvature radii of the two sides of double concave lens are equal. It is generally used for beam expansion and projection. The principle of geometric drawing of biconcave lens...
The line connecting the centers of curvature on both sides is called the principal axis, and the central point O is called the optical center. Light passing through the optical center does not refract no matter where it comes from. The beam parallel to the main axis refracts on the concave lens and diverges to the...
Lens is a kind of refractive optical element made of different optical materials. Its refractive surface is two spheres or one sphere. According to its shape, it can be divided into convex lens (positive lens) and concave lens (negative lens). The lens whose central part is thicker than the edge is called convex lens....
Roof prism is usually the general name or synonym of optical prism that can simply change the direction of light through reflection by 90 °. Images reflected and flipped through two planes will meet on the optical axis and flip to the side. Introduction roof prism is usually the general name or synonym of optical...
Optical domes Due to the limitations of our manufacturing machines, we only can provide optical domes with the diameter of less than 124mm at before. is a Well-known optical dome manufacturer and we know that large optical domes have a good market, because it can provide a large viewport protected space. Purchasing...
Optical lens Design for mobile
The variant of pentaprism is roof pentaprism, which is usually used in monocular camera. In this case, because the image projected on the fuselage will rotate 180 ° after the lens is focused, the light beam reflected from the plane mirror to the pentaprism after the focus also needs to change the left-right...
