Paper Abstract

Compatible core and clad glasses transmitting peak uv radiation at 320nm have been developed for fiber optic applications. Research was conducted to formulate compositions having high transmission in the near- and medium-ultraviolet region and capable of being fabricated into fiber optic faceplates for ultra-high resolution cathode ray tubes. The glass forming the radiation transmitting core is a lanthanum-zinc-borate composition having an index of refraction (nd) of 1.71 and peak internal transmission of over 80% at 320nm for 1/4-in. thick-ness. A matching potassium-alumino-boro-silicate cladding glass having a low index of refraction (nd = 1.47) was also developed. Both glasses possessed compatible coefficients of thermal expansion and softening points to produce faceplates having fiber centers approaching five microns in spacing. A theoretical numerical aperture in excess of 0.8 is achieved with these glasses.
