Abstract

In this paper, we present four diffractive objectives for a 240 X 320 pixel PtSi staring array. The focal lengths for these lenses range from 12.5 mm to 100 mm and they have a relative aperture of F/2. Various system constraints and their impact on the optical designs are addressed. In addition, measured and predicted performance data are compared.
