Design of an athermalized three field of view infrared sensor
Abstract
Design methods and predicted performance of an afocal field-of-view changer for an existing IR camera operating in the 3-5-micron atmospheric transmission region are described. The athermalized changer is predicted to maintain focus within the 1/4 wave criteria over -40-60 C temperature range.
