Abstract :
A design of optical system for CCD matrix photo-receivers including optical elements with antireflection coatings for wide spectral region between 8 and 12 mum is presented. Analysis of objective´s design based on Ge and GaAs lenses with multilayer AR coating using materials with high refractive index (Ge) and low refractive index (ZnSe, ZnS, SrF2) is carried out. Optical quality of the objectives (image quality) is estimated.
