The concepts of thermal-imaging as applied to the growth of single crystals are presented. A brief history of thermal-imaging is covered with special emphasis on the work done at AFCRL. The design and construction of a vertical furnace embodying these principles is covered together with its use for the growth of a number of single crystals. The furnace represents an advance in the techniques of growth of single crystals of many materials with Air Force applications, including laser hosts, substrate materials, and permanent magnet alloys. It makes possible the growth of these materials without contamination from crucibles and in optimum atmospheres. Author
