6 December 1993 Production of gallium arsenide IR windows
Author Affiliations +
The advantages and disadvantages of several methods used to prepare gallium arsenide will be discussed relative to the preparation of large plates to be used as IR windows. Amorphous Materials chose to use the Horizontal Bridgman process to prepare plates 4 inch X 9 inch X 0.5 inch. Doped and undoped plates were prepared. Optical and electrical evaluation data will be presented. Scale up to larger sizes will be discussed. A unique process to protect gallium arsenide from rain erosion, provide EMI protection and de- icing capability will be described.
