The design method and result are described for an infrared afocal zoom system. Its zoom ratio is 4
(2) Functions such as changing the field-of-view
and the corresponding field of view is 3-12. The working waveband is from 7.5m to 10.5m
focusing for objects at finite distances and athermalizing the system can be achieved by axially moving a single element in the system.
and its total length is required to be no more than 350mm. The final optical system consists of 7 elements
with aspheric surfaces and a diffractive optical element. It achieves diffraction-limited imaging at the far infrared waveband. Two conclusions can be drawn from the design. (1) Using diffractive optical elements in the design of an infrared optical system is an effective approach to control color aberrations
which eliminates the need to use exotic and expensive materials and helps to reduce the cost of the system
