Abstract
Short-Wave (SW)* ultraviolet transmitting filters that absorb visible light were obtained in 1985-86 from five manufacturers of filters and ultraviolet (UV) light assemblies. Two blind solarization tests were conducted in which 30 samples were evaluated to determine the effect of UV radiation on the filters over time. The radiation source consisted of two G30T8 germicidal lamps. The transmission of each filter was measured by a Perkin-Elmer Lambda 9 spectrophotometer at 253.7nm. The transmission of each filter sample was also periodically measured from 200nm to 800nm during the first test. The results of the solarization tests were then plotted as percent transmission at 253.7nm vs. hours of exposure to SW UV. The results demonstrate significant differences in solarization rate between SW filters.
