Abstract

Embodiments include an optical system comprising a plurality of powered optical elements, arranged within a same optical path, configured to simultaneously pass and focus therethrough mid-wave infrared (MWIR) and long-wave infrared (LWIR) spectral bands to a focal plane array (FPA) and provide simultaneous correction of monochromatic and chromatic aberrations over the MWIR and LWIR spectral bands with a low f-theta distortion. The plurality of powered optical elements comprises a first set of powered lenses having a passive athermalized response over fluctuating temperatures in a variable temperature environment; and a second set of powered lenses to operate in a constant cryogenically cooled environment. A method and a situational-awareness device are also disclosed.
