摘要：

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 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 mum). The coating allowed continuous transmission of high power density (up to 3 W/mm(2)) of IR radiation produced by CO2 laser. The laser irradiation damage threshold of the PANI EB coating was studied at a wavelength of 1.5 mum. Microhardness of the coated ZnSe is established as satisfactory. (C) 2003 Elsevier Science B.V.
