Experiments operating in the VUV as well as those employing cryocooled optical surfaces are the most seriously affected by spacecraft contamination due to outgassing of foreign materials, reaction byproducts of thruster firings, system venting emissions, etc. Attention is presently given to a self-contained optical contamination monitor, furnishing in-flight and/or real-time monitoring of VUV reflectivity and transmittance. The time-lining of measurement results with other spacecraft events will allow the direct evaluation of spacecraft operation effects on critical optical surfaces.
