Abstract
Heavy metal fluoride glasses (HMFG) based on ThF4, which exhibits a large transparency domain from 0.2 pm to 8 pm, have been optimized in three directions. The devitrification tendency has been decreased by using InF3 as doping while maintaining the I.R. transparency in the 8 pm region. Purification by a RAP technique using CS2 has been applied to eliminate hydroxyle and oxygen contamination. The corrosion of HMFG by atmospheric moisture during the melting and annealing operations has been investigated.© (1984) COPYRIGHT SPIE--The International Society for Optical Engineering.
