| Summary: | Molecular contamination outgassing from non-metallic spacecraft materials is deposited on sensitive surfaces after diffusion, thereby degrading the performance of the optical device. To investigate the effect of nonmetal contamination on optics, non-metallic mixing film was prepared on a glass substrate using an improved method of ASTM E 1559, and the transmittance was measured using a spectrophotometer. To more accurately simulate the transmittance of contamination film, an optical contamination effect model was established based on diffusion theory, angle coefficient method, first-order desorption equation, Lorentz-Lorenz relation and wave propagation in hierarchical media and dielectric film theory. The simulation results are in good agreement with the experimental values. |
