Abstract
An optical system comprising includes an off-axis folded three mirror anastigmat (TMA) telescope including a primary mirror for receiving energy from a scene. A secondary mirror is aligned to receive reflected energy from the primary mirror. A fold mirror is aligned to receive reflected energy from the secondary mirror. A tertiary mirror is aligned to receive reflected energy from the fold mirror and to direct energy between the secondary mirror and the fold mirror. A beam splitter is aligned to receive energy reflected from the tertiary mirror, to reflect a portion of that energy to a first imaging sensor, and to pass a second portion of that energy to a second imaging sensor.
