Silicon Optical Lenses  is a single-component amorphous material of silica. Its microstructure is a simple network composed of silica tetrahedral structural units. Because Si-O has a large chemical bond and a very close structure, Silicon Optical Lenses have unique properties, especially for transparent Silicon Optical Lenses, which have excellent optical performance and excellent transmittance in the continuous wavelength range from UV to IR. Silicon Optical Lenses has a very low coefficient of thermal expansion, high-temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, excellent UV transmission performance, and visible and near-infrared Spectral performance, and has higher mechanical properties than ordinary glass. Silicon Optical Lenses is an acidic material that, besides hydrofluoric acid and hot phosphoric acid, is inert to any other acid and is a good acid-resistant material. The degree of corrosi

　 Plano Convex Lenses  can also make a fire that many people don't know, so how do the convex lenses make a fire. Let me tell you. 　　The convex lens has the function of collecting light. When the sunlight is refracted by the convex lens, it will be concentrated at the focus. The energy of the light received at this focus is very high. If the flammable object is placed at the focus, it is easy to ignite. It is well known that a convex lens is used to illuminate a flammable firelight (the rot, the yarn extracted from the cloth, the dried thin bark, the dried wood chips, etc.) through the sunlight. In addition, the magnifying glass can be illuminated by the sun through the focus of the sun, and the vicious lens can be ignited by the wet or wetted water so that the convex lens is an important ignition tool. 　　In  Optical Lenses , convex lenses are especially common and widely used. The convex lens is a lens with a thick center and a thinner edge. Convex lenses have the effect of c

Plano-Convex Lenses Fused Silica Plano-Convex Lenses with 1064 nm Laser Line Antireflection V-Coating Fused silica Plano-Convex lenses  are the best choice for focusing parallel rays of light to a single point.With AR coated fused silica Plano-Convex lenses can offers best optical performance. Our AR 1064nm laser V-coating offers the low reflectance at 1064 nm for high transmission, reduce to surface reflection and scattering. And our coating have high damage resistance, it will be keep the lenses maintaining high durability.

We are good at supply custom lenses from your design, our manufacturing capacity from diameter 10mm up to diameter 200 in a full range of optical glass materials to meet most applications, and we are a

In  Optical Lenses , light energy is lost due to the reflection of the surface of the element. In order to reduce the reflection loss on the surface of the element, a transparent dielectric film is often plated on the surface of the optical element. This film is called an anti-reflection film. 　　The principle of increasing the transmission of the AR coating can be qualitatively analyzed from the perspective of energy conservation. The principle of increasing the transmission of the AR coating according to the Fresnel formula and the law of refraction can be quantitatively explained. The electromagnetic theory of electrokinetics is used to increase the AR coating. The principle of transmission gives a theoretical explanation. Optical Coatings 　　What should you pay attention to in the processing of  Optical Coatings ? When light enters different transfer materials (such as air entering the glass), about 5% will be reflected off. There are many lenses and refractors in the optica
