Germanium windows
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, excellent
surface 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 window is applied to isolate different physical environments while
allowing light to pass through an antireflection coating is typically
applied to windows to minimize losses due to reflections.
The protective windows are used to protect scan lenses from backsplatter
and other workplace hazards.
The Brewster windows are uncoated substrates used in an optical system at
Brewster’s Angle.While virtually allof the p component of polarization
is transmitted by a Brewster Window, most of the s component is reflected.
A Brewster Window causes polarized laser output.
