1.Detailed Description:
Sapphire possesses nice light transmission in 0.20 ~ 5.50μm wave band, and the infrared ray transmission is hardly influenced by temperature, so the optical components made of sapphire are fully applied to infrared equipment, low-temperature laboratory viewing aperture, navigation and aviation high precise apparatus, etc.
We offers all kinds of lenses, i.e, plano-convex, plano-concave, bi-convex, bi-concave, meniscus, achromatic and cylindrical lenses, which are made from different material, such as BK7, fused silica, optical glasses, sapphire, CaF2, Silicon etc.
2.Typical Applications:
① Optical surfaces
② Imaging optics
③ Corrosion-resistant surface
