Paper Abstract

Filters are employed in optical systems to reduce stray light and block unwanted spectra. However, common filter materials are susceptible to solarization, a bulk degradation wherein the material properties change when exposed to UV radiation. A new decay model is developed to describe this behavior. Solarization effects for various kinds of filters are measured and recommendations for mitigation are made.
