N2 - The use of polyaniline emeraldine base films as antireflection coating for near and middle IR optics elements was studied. The optical quality of ZnSe substrates spin-coated with thin PANI EB layers were studied using a Linnik interferometer. The spectral properties of PANI coated ZnSe plates were investigated in broad IR band with FTIR spectrometer. It was shown that PANI coating allows a significant decrease of Fresnel losses in the near and middle IR bands (1.0 - 6.25 μm). The coating allowed continuous transmission of high power density of IR radiation produced by CO2 laser. The transmission coefficient doesn't depend on the incident laser beam power density (up to 3 W/mm2). The laser irradiation damage threshold of the PANI EB coating was studied at a wavelength of 1.5 μm and established as high as 0.1 GW/mm2 (τ = 12 10-9s) for PANI EB coating with a thickness of 150 nm. Microhardness of the PANI EB coated ZnSe plates was established as satisfactory.
