The role of the lens in the optical system is: focusing, collimating, imaging. Huizhou Yisu

Photonics can produce: plano-convex lenses, plano-concave lenses, biconvex lenses, biconcave lenses, meniscus lenses, cemented lenses, cylindrical lenses, etc. Nearly a decade of optical product processing experience and a complete prism lens processing production line. Anti-reflection coating can be applied to reduce the reflection on the lens surface according to customer requirements. This can reduce the loss of light energy and make the imaging clearer.

Lenses can be widely used in various fields such as security, automotive, digital cameras, lasers, optical instruments, etc. With the continuous development of the market, lens technology is also more and more widely used. (Lens) lens is made according to the law of light refraction. The lens is an optical element made of transparent material (such as glass, crystal, etc.). The lens is a refracting mirror, and its refractive surface is two spherical surfaces (part of the spherical surface), or a spherical surface (part of the spherical surface) and a flat transparent body. The images it creates have real and virtual images.
