Wide-angle, broadband anti-reflection coating and corresponding infrared gas sensor light sources.
Since specially designed identical coating systems are deposited on both the top and bottom surfaces of the ZnSe substrate, the thickness of each layer for different requirements can be obtained using optical coating design software according to various incident angle requirements.
It is suitable for a wide range of applications, is simple and convenient, and achieves excellent anti-reflection performance when applied to infrared gas sensor light sources.
Substrate: Ge, ZnSe, etc.
Size: Customized as per customer requirements
Specifications: 2–12 μm, average transmittance >92%
