Results are presented of testing performed to measure the effects of material outgas products on the reflectances of ultraviolet-region mirrors. These tests were to provide data on changes of ultraviolet reflectances of first-surface mirrors which had been exposed to the outgas products of selected materials under specific time and thermal-vacuum conditions. The requirement for such data was based on the extreme sensitivity of the sophisticated optical instruments in the Skylab mission's Apollo Telescope Mount (ATM) to condensed outgas products from materials, and on the desire to insure that no serious hazard of contaminating these instruments existed.
