Product Details

Germanium window Ge window with 3-12um AR coating

Germanium is a versatile infrared material commonly used in imaging systems and instruments in the 2 to 12 microns spectral region.It is non-hygroscopic and non-toxic, has good thermal conductivity, excellentsurface hardness and good strength.It is used as a substrate for lenses and windows in the 8 to 12 or3 to 5 microns spectral region.

The coating: Anti-Reflection Coatings ,AR Coating @ 10.6μm;BBAR Coating @ 8-12μm;

The material can be Schott, or CDGM optical glass serious. They are low distortion, low scatter, and could be for laser and non-laser applications.

Material are available for BK7,JGS1,Sapphire,CaF2,MgF2,BaF2,other material as customer need.
