Paper Abstract

A triplet is described which consists solely of spherical surfaces in common IR transmitting materials. It has a speed of f/0.75 and is achro-matized over 8-12 microns. The resolution is diffraction limited over its 12° field of view. This lens was designed utilizing a fundamentally new computer optical design program written by David S. Grey at the MIT Lincoln Laboratory. The concepts underlying this program will be briefly described.
