Abstract
Space environment in which the space optical system exposed includes space vacuum, cryogenics, and energetic particles and etc. The contamination effects on the space optical system, so the optical damage occurs. And the image quality of the system will be affected. In this paper, the effects of contamination to optical system were discussed, and the contamination source and its space distribution were analyzed. An experiment was designed to determine the effect value. Numeral fitting method was used to analyze the relationship of the optical damage factor (Transmissivity decay factor) and the contamination degree of the optical system. In the experiment, the contamination degree was expressed by mass thickness with the unit μg/mm2. Oil paint was used as the contamination source. Comparison between previous and present researches was given.
