Paper Abstract

The design of a large infrared refractive re-imager for use in the 3 - 5 micron waveband is described. Comparisons are made with designing for the longer 8 - 12 micron waveband. In particular, key design aspects of achromatization, athermalization, thermal gradients, and manufacturing sensitivity, have been emphasized.
