Description

technical field [0001] The patent of the present invention mainly relates to an analysis test system for the influence of pollutants deposited by outgassing components on optical transmittance, which can accurately and quickly analyze the influence of different levels of pollutants on optical transmittance. Background technique [0002] During the operation of the spacecraft in orbit, the vacuum environment and the hot and cold environment will cause various non-metallic materials used on the spacecraft to outgas, and the organic molecular pollutants released will be deposited on the surface of the spacecraft with a lower temperature. Contaminant deposition will affect the optical performance of sensitive components of the spacecraft, such as affecting the transmittance performance of optical surfaces. [0003] The influence of outgassing pollutants from non-metallic materials of spacecraft on optical transmittance is analyzed. It is necessary to establish a space vacuum en...

AI Technical Summary

Problems solved by technology

[0004] At present, the analysis test of the influence of material degassing on optical transmittance is usually carried out in a vacuum environment, heating and degassing the material, and at the same time using an optical test piece to sample pollutants, and using an electronic balance to weigh the optical test piece before and after the test. Heavy, to obtain the magnitude of the sampled pollutants; this method cannot monitor the magnitude of the surface deposited pollutants in real time, and can only estimate the magnitude of the pollutants through the experience of multiple tests; and it cannot analyze the optical transmittance of small-scale pollutants Influence; and the pollution test method adopted may be affected by human and environmental factors, resulting in large measurement errors
