Our germanium lenses Have got a significant refractive index—the highest refractive index amid readily available IR transmitters. In addition it reveals minimum chromatic aberration because of very low dispersion.
Germanium is additionally subject matter to thermal runaway. What this means would be that the transmission will lower as temperature boosts, and the lens results in being opaque. For that reason thermal runaway influence, germanium lenses should only be made use of at temperatures under one hundred°C.
If high transmission is the only thought, you’d be ideal served to double coat your windows with BBAR over unique wavelength ranges and you can see transmissions every one of the way approximately 99%. Now we’re chatting!
