Sapphire possesses nice light transmission in 0.20 ~ 5.50μm wave band, is ideal for laser and infrared optical materials. Products widely used in endoscope,watch glass, optical lens, surface acoustic wave filter, military infrared window, optical filter, observation window for high/low temperature and cosmetic instrument windows, etc. We can provide anti-reflection film, high-reflective film, dielectric film, filter film and metallized film services.
Sapphire optical lens is usually used to change the direction of light transmission to control the imaging accuracy, angle, etc. Sapphire material has good transmittance, so, lens made of sapphire materials have longer life, adapting to a wide spectrum compared with optical glass.
Processing different types of sapphire convex lens according to user's requirements. Such as: plano concave lens, double concave lens, bi-concave lens, pcv cylindrical lens, bcv cylindrical lens..
