Abstract

Based on the principle of passive optical athermalization, a wide field medium wave infrared optical system is designed for working at -40℃-60℃. A 320×240 focal plane array (FPA) detector as image plane is used in the system. The system has a field-of-view of 30°×22.72° and a relative aperture of f/2 at 3-5 µm with 100% cold shield efficiency. The modulation transfer function (MTF) of each field is greater than 0.6 at the Nyquist frequency and the maximum distortion is less than 3% at -40℃-60℃. The system can meet the demand of the excellent image quality. This work is valuable for athermalization design of wide field medium wave infrared optical system.
