ABSTRACT:
An infrared lens assembly (16, 60 and 80) operative in the near and far infrared wavebands to focus infrared radiation at an image plane (15) of an infrared detector (18). The infrared lens assembly (16, 60 and 80) includes a focusing component (33, 63 and 83), a collecting component (37, 65 and 85) and a diffracting component (41, 67 and 87). The focusing component (33, 63 and 83) and the collecting component (37, 65 and 85) may be formed from high dispersion, low index material. The diffracting component (41, 67 and 87) may be used to correct color aberrations associated with an infrared waveband.
