Abstract

The optical filter for 8-12 microns spectral range on the base of MCT epilayer grown by Metal Organic Chemical Vapor Deposition (MOCVD) has been investigated. The CdTe mole fraction in Cd_xHg_1-xTe equals x=0.24. The single-layer antireflection coatings for 10 μm peak wavelength have been deposed on the both sides of the filter. Transmission in 8-12 μm spectral range exceeds 70%. Transmission at 7 μm is of 40%, at 6 μm-10%, at 5 μm-less than 2%.
