Abstract
A compact coaxial optical system is described that employs a Cassegrain telescope with switchable primary mirrors plus a catadioptric relay. The system can operate in the visible, near/thermal IR, and millimeter wavebands, is athermal, and provides multispectral compensation for a protective dome.
