Abstract : This report summarizes efforts carried out under a Small Business Innovative Research (SBIR) Phase II contract, whose purpose was to assess the feasibility of producing large bulk articles of heavy metal fluoride glass (HMFG). The HMFG are a family of non-oxide vitreous materials with broad range of transparency (ultraviolet to mid-infrared), and are potentially useful as multispectral optical components and optical fibers. The present report supplements and expands on the results obtained under an SBIR Phase I contract (F30602-83-C-0189) described in an earlier RADC Final Technical Report (RADC-TR-84-279). In the course of this effort, a variety of facilities, apparatus and techniques were established to upscale and improve HMFG fabrication technology. Glass compositions, laboratory-scale melting methods, and characterization techniques developed in the course of RADC in-house basic research programs were transferred to the contractor for evaluation in an industrial setting. Keywords: Fluoride glasses; Optical fibers; Infrared materials, Nonoxide glasses, Infrared fibers, Electromagnetic windows.
