  A system and method for modeling the effect of a molecular contaminant film on performance of an optical system is disclosed. A mass of material outgassed from materials of the optical system is correlated to spectrum of outgassed products. The spectrum of outgassed products is normalized, and an aggregate molecular contaminant film thickness is predicted from each material. The absorbance spectrum of the aggregate molecular contaminant film is derived, and the derived absorbance spectrum of the aggregate contaminant film is convolved with an optical system instrument function. A plot of at least one transmission band as a function of source temperature is performed to determine the degradation in performance of the optical system.

  本发明公开了一种用于模拟分子杂质膜对光学系统性能影响的系统和方法。从光学系统材料中排出的材料质量与排出产物的光谱相关联。出气产物的光谱被归一化，并根据每种材料预测出分子杂质膜的总厚度。得出聚合分子污染膜的吸光度光谱，并将得出的聚合污染膜吸光度光谱与光学系统仪器函数进行卷积。绘制至少一个透射带与光源温度的函数关系图，以确定光学系统的性能下降情况。
