Paper Abstract

For a number of years we have been conducting modulation transfer function (MTF) analyses on infra-red lenses and windows using (1) line spread function (LSF) and (2) interferometric measurements. Although generally comparisons between results obtained from the two methods have been good, there have been some occasions when differences have been observed. This paper presents some of the results and discusses possible causes for the discrepancies.
