Paper Abstract

The ability to successfully fabricate an optical element has as its bounds on contour accuracy and functional system performance the level to which these features can be charact erized via test methods. In addition, product saleability and satisfaction, of specification must also be provided in a production-compatible optical evaluation program. These restric tions are even more severe in the case of a diamond-turned sample, particularly aspherics. The impact of slope-errors, finish and subsurface micro structure on the imaging properties of an element as a result of the diamond-turning process is to this point illdefined and must become an important part of an overall characterization scheme. While a measure of the element Optical Transfer Function (OTF) would provide proof of suitability in its wavelength of use, the costly, non-universal nature of this test precludes its use in a production. environment. This paper addresses an overall characterization program for diamond-turned elements for infrared-systems use which will provide specification verification, systems performance parameters and production. buy off potential while remaining compatible with needs of production-level operation.
