Paper Abstract

Fluor crown glasses, having improved transparency in the UV-spectral region, can be produced by using a proprietary melting technique. The short wavelength cut on of this family of UV-transmitting glasses is similar to that of vitreous silica. In the present investigation the effect of broadband UV-radiation has been studied as a function of time and optical absorption primarily for the glass type UVFK-54. Further tests were performed using discrete line radiation of 248 nm from a pulsed excimer laser. The intensity of the darkening effect is correlated to the intensity and dose of radiation. In addition, recovery experiments using elevated temperatures and different times are discussed.
