Abstract: A Mid-Wave Infrared (MWIR) objective lens having an F # of 2.64 and a 33.6° angular field of view. It is deployed, with a focal plane and scanning system, on an airborne platform for remote sensing applications. Focal length is 9 inches, and the image is formed on a focal plane constituting CCD or CMOS with micro lenses. The lens has, from object to image, three optical element groups with a cold shield/aperture stop. Group 1 has a positive optical power and three optical elements; Group 2 has a positive optical power and four optical elements; Group 3 has a positive optical power and three optical elements. The objective lens is made of two Germanium and Silicon. The lens is both apochromatic and orthoscopic, and corrected for monochromatic and chromatic aberrations over 3.3 to 5.1 micrometers.

Abstract: An athermal and achromatic lens with a high resolution while further being near orthoscopic and providing a large field of view. Further, the provided VNIR lens may utilize only three types of optical glass allowing the lens to be reduced in size, cost, and weight while further reducing or minimizing the complexity thereof.
