IR Atmospheric Window Filter
- High transmission in NIR wavelengths
There is a small amplitude in passband. - Flexibility of interference films design
Multi bandpass design with different wavelengths is available. - Excellent environmental durability
MIL-specifications compliant
Interference film coated by magnetron sputtering technology has excellent
durability against harsh environment.
The mid-wavelength infrared (MWIR) atmospheric window is required for thermal
imaging applications.
We achieved the quadruple bandpass filter to make the atmospheric transmission
derived from the solar spectral irradiance.
