Paper Abstract

The test and evaluation of infrared optical systems is requiring collimators with rather stringent performance characteristics which must be simultaneously realized. Fields of view as large as 15 degrees, flat focal surfaces, clear apertures with uniform intensity across the focal plane and minimal spectral variations over passbands as wide as 7 pms are within the realm of common place. A centered, rotationally symmetric optical system with a tilted field of view and a decentered stop has been used to design just such an optical system. Evaluation shows that it meets performance requirements and that it is nearly diffraction limited over the central 5 of its 15-degree field of view.
