Sažetak
The effect of reactor neutron irradiation on the optical properties of ZnS - cryolite Fabry-Perot interference filters was investigated. Optical transmittance spectra of the filters were taken before and after irradiation; neutron fluxes in the range of 10^13-10^18 neutrons/cm^2 were used. The shift of the peak transmittance wavelength as well as the decrease in transmittance were observed for neutron fluxes higher than ~ 10^17 neutrons/cm^2 . The change in the peak transmittance wavelength was related to the change in optical thickness of the layers, i.e. to the change in refractive index and geometrical thickness induced by neutron irradiation. The decrease of the density as well as of the index of refraction of ZnS layers was calculated using the experimental results and a simple displacement theory.
