Product Description

General Introduction: Raytek produces infrared germanium lens, using optical grade single crystal germanium as the substrate, using new polishing technology processing, the surface has a very high surface accuracy, germanium lens two surfaces will be plated with 8-14 μ M antireflective film, can greatly reduce the reflectivity of the substrate, antireflective film working band transmittance of more than 95%.

Products Name: 
Infrared lens/Infrared Ge Lens/Infrared Germanium Lens/IR Ge Lens/IR Germanium Lens
Alias:Infrared lens,Infrared Ge Lens,Infrared Germanium Lens,IR Ge Lens,IR Germanium Lens, IR Lens, Germanium Infrared Lens,Ge Infrared Lens, Germanium IR lens, Ge IR Lens,etc
,etc

Main Applying:

Applying 1	Infrared thermometers;
Applying 2	Infrared thermal imagers;
Applying 3	CO2 Lasers;
Applying 4	Multi-laser systems;

Main Highlights:
The wide spectral range of germanium (2-16um) Germanium is very suitable for infrared laser applications because of its high transmittance in the visible spectrum.It also does not react easily with air, water, alkali metals and acids (except nitric acid)
