1.Detailed Description:
Sapphire possesses nice light transmission in 0.*0 ~ 5.*0μm 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:
â‘  Optical surfaces
â‘¡ Imaging optics
â‘¢ Corrosion-resistant surface
3.Technical Index:
 

• Transmittance under **2.8nm wave length >*5%

• Center deviation＜ 3′
• Surface Figure: λ/2
• Surface quality: S/D*0/*0
