title = "Design of a three field-of-view IR system",
abstract = "The design method and result are described for an infrared zoom system with three fields of view. Its zoom ratio is 9, and the corresponding field of view is 3°-27°. The working waveband is from 3 μm to 5μm, and its total length is required to be no more than 400mm. The final optical system consists of 9 elements, with two aspheric surfaces and a diffractive optical element. It achieves diffraction-limited imaging at the middle infrared waveband. From the last result we can know using the diffractive optical elements can eliminate the color aberration and helps to reduce the cost of the system; and using the rotated elements in the system it is easy to change the field-of-view and satisfied the cooled detector requirements.",
