INVESTIGATIONS ON EXTENDING THE SENSITIVITY RANGE OF SINGLE CRYSTALS AND EVAPORATED FILMS OF SILVER BROMIDE

Abstract

Two methods for achieving panchromatic sensitivity in ingle crystals and evaporated films of AgBr were investigated. THE USE OF CONVENTIONAL PHOTOGRAPHIC SENSITIZING DYES PROVED PROFITABLE. Over-all sensitivities obtained with evaporated films ere of the order of ASA 1. Sensitivity to light passing a Wratten 25 filter was of the order of 0.01. With single crystals, sensitivities obtained were l wer by a factor of 10. Methods were developed f r scaling up of procedures to allow preparation of larger amounts of pure AgBr and larger amounts of evaporated film. A developer particularly suited for use with single crystals and evaporated films as formulated. Some additional chemical sensitization procedures and an improved transfer method were studied. An improved resolution camera was set up and is being modified. 9author)
