Abstract:
The change in the working characteristics of the optical element sample depending on the thickness of the contamination film applied to the sample has been estimated experimentally. As sources of contamination, the coatings of lens hoods were chosen, which are located in close proximity to the contamination- sensitive optical system of a spacecraft. A series of experiments for applying contamination films of different thickness to the sample of the optical element has been carried out. Based on preliminary estimations, the thickness of the contamination during the entire period of the active existence of the spacecraft will not exceed 3500 Å.
