Abstract

Bidirectional reflectance distribution function measurements of optical surfaces both before and after molecular contamination have been done using UV, VUV, and visible light. Molecular contamination of optical surfaces from outgassed material has been shown in many cases to proceed from acclimation centers, and to produce many roughly hemispherical "islands" of contamination on the surface. The products of this outgassing will inevitably migrate throughout the surrounding area and adhere to any convenient surface, including optical elements in the system.
