13. An optical system comprising:
an off-axis folded three mirror anastigmat (TMA) telescope including a primary mirror configured to receive scene energy, a secondary mirror configured to receive reflected energy from the primary mirror, a fold mirror configured to receive reflected energy from the secondary mirror, and a tertiary mirror configured to receive reflected energy from the fold mirror and to direct energy between the secondary mirror and the fold mirror;
a first interchangeable module configured to be removably connected to the TMA telescope, the first interchangeable module comprising a first imaging sensor sensitive to at least a first plurality of wavelengths and a second imaging sensor sensitive to at least a second plurality of wavelengths, wherein the first interchangeable module is removable and replaceable with a second interchangeable module comprising a third imaging sensor sensitive to at least a third plurality of wavelengths and a fourth imaging sensor sensitive to at least a fourth plurality of wavelengths;
a pod configured to house the TMA telescope and the first interchangeable module within the pod; and
a single window configured to allow scene energy into the pod to the TMA telescope.
