Abstract:

Efforts during this reporting period were concerned with the determination of the effect of solarization on lasting characteristics of several glass compositions under investigation and a continuation of athermalization studies begun previously. The procedure used in the solarization tests is described results obtained indicate decreased slope efficiencies and increased threshold values are uncorrelated with solarization. Based on encouraging results obtained from measurements of the change in optical pathlength on a modified athermal glass composition, a second series of 16 athermal glasses was prepared. Finally, efforts to finalize the procedure for measuring stress-optical coefficients are described.
