Paper Abstract

A new design of a thermal imaging system which incorporates diffractive surfaces in order to enhance system performance is presented. The problem of the drastic vignetting, typical of Galilean telescopes, is solved by using a Keplerian telescope with a very small f-number (approximately 0.7). In addition, several other aspects of design, manufacturing and tolerancing are discussed.
