Effect of Exposure Test on Transmittance of Molecular Contaminant
Abstract
Molecular contamination is a concern for sensitive optics of astronomy satellites and earth observation satellites. The contaminants decrease the transmittance of lenses and optical filters, and the reflectance of mirrors. The absorptance of the diethylhexyl phthalate, as a model contaminant, depended on ultraviolet irradiation time and the contaminant thickness.
