An optical lens is an optical element whose surface is part of a spherical surface made of transparent material, which is made according to the refraction law of light.
A lens is a refractor whose refracting surface is a transparent body with two spheres (part of the sphere) or one sphere (part of the sphere) and one plane. Convex lens: thick in the middle and thin at the edge, including biconvex, flat convex and concave convex; Concave lens: thin in the middle and thick at the edge, including double concave, flat concave and convex concave.
Optical lens realizes light aggregation, Flat window,Manufacturer of spherical lens light dispersion and optical imaging by using the principle of light refraction in the optical system. It can optimize color correction and correct spherical aberration.
The optical lens can be widely used in various fields such as safety, vehicle, digital camera, laser, optical instrument and so on. With the continuous development of the market, lens technology is becoming more and more popular.
The function of optical lens in optical system is focusing, collimating and imaging. The lens usually needs to be coated with antireflection film to reduce the reflection of the lens surface, which can reduce the loss of light energy and make the imaging clearer.
Tips for selecting optical lens
1. The distance of the product is affected by its own angle;
2. Follow the measurement results;
3. Select according to the light intensity requirements.
Use of optical lens
1. Fiber array coupling;
2. Optical communication;
3. Reconfigurable optical add drop multiplexer, Flat window,Manufacturer of spherical lenswavelength selection switch;
4. Multiplexer / multiplexer, optical cross connect equipment.
Optical lens is a device that can concentrate or disperse light, which can affect the wavefront curvature of light. The images produced include both real and virtual images. All kinds of common colorless optical glass, including quartz, calcium fluoride, magnesium fluoride, silicon, germanium, zinc selenide and other materials, Flat window,Manufacturer of spherical lens as well as flat convex lens, biconvex lens, flat concave lens, biconvex lens, super hemispherical lens, small spherical lens, meniscus lens, cylindrical mirror, strip mirror, bonding mirror and so on.
