Long Wavelength Optics Fabrication.
Abstract
An investigation was undertaken of the problems associated with fabrication of far infrared optical elements. The objective was to develop and document procedures for the cost-effective fabrication and testing of far infrared lenses for imaging and non-imaging fire control systems. The physical properties of optical grade germanium were examined. An effort was made to correlate information acquired in these activities, in order to examine critical aspects of each step in the lens-making process in light of the material profile of germanium. The early stages of the lens-making process are covered in this report. Shop procedures were developed and are included in an Appendix. The procurement and testing of optical grade germanium are examined and discussed. It was concluded that the techniques used in the fabrication of optical glass lenses can be used, with minor modifications, for the manufacture of germanium lenses.
