Abstract
A reflective afocal switching assembly permits variable fields of view while at the same time providing a common axis and mechanism to achieve an optical de-roll of the image. This complex arrangement provides a relatively large change in magnification for an all-reflective optical system than can image over 0.4-12.0 micron spectrum.
