• 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.
