Abstract : This is the final report under the contract for work performed between 1 July 1967 and 30 March 1971. The objective of this project was to develop and fabricate fiber optic faceplates for cathode ray tubes with a high numerical aperture and high transmission in the near and middle ultraviolet spectral regions. New glasses were developed with the required properties and capable of being fabricated into 5-in. fiber optic faceplates. A lanthanum-zinc-borate core glass having an index of refraction of 1.71 and a peak internal transmission of over 80% at 320 nm (1/2-in. thickness) was developed. A matching potassium-alumina-boro-silicate cladding glass having a low index of refraction, 1.47, was also developed. Fiber optic faceplates, fabricated from these glasses, had a theoretical numerical aperture in excess of 0.8. Six full-size faceplates were fabricated, mounted in metal flanges, and delivered to the Army for incorporation in CRT's. (Author)
