Abstract: A mid-wave infrared (MWIR) lens assembly that may include a first set of optical elements, wherein each optical element of the first set of optical elements is a positive optical power. MWIR lens assembly may also include a second set of optical elements, wherein each optical element of the second set of optical elements is a negative optical power. MWIR lens assembly may also include that at least one optical element of the first set of optical elements is formed of a first optical glass material, at least another optical element of the first set of optical elements is formed of a second optical glass material, and at least one optical element of the second set of optical elements is formed of a third optical glass material wherein the second optical glass material is different than the first optical glass material and the third optical glass material.

Abstract: A Mid-Wave Infrared (MWIR) objective and relay lens system has an F# of 3.33 and angular field of view of 15.28°. It is deployed, with a focal plane and scanning system, on airborne platforms for wide area motion imagery. It is corrected for monochromatic and chromatic aberrations over of 3.3 to 5.1 micrometers. Effective focal length is 20 inches, and the overall length is 40.70 inches. The lens has, from object to image, two groups of optical elements with a cold shield/aperture stop 6 inches from the image plane. Group 1 acts as an objective lens with a positive power and three elements, Group 2 acts as a relay lens has a positive power and four elements. The lens is made of Germanium and Silicon. It used in a scanning system in a pre-objective configuration where the fast scan mirror is located in front of the lens system.

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: A mid-wave infrared (MWIR) discrete zoom lens for use with remote surveillance and identification having a dual focal length of 9 and 6.39 inches and F #2.8 and F #2, respectively. In one case, a full field of view is about 30.8 degrees for a 9 inch focal length configuration and about 43 degrees for a 6.39 inch focal length configuration. The lens is corrected for monochromatic and chromatic aberrations over the wavelength range 5100 nm-3300 nm. The focal plane may constitute a pixel array consisting of MWIR sensitive material (e.g. InSb, HgCdTe, nBn, SLS, etc.) for use in high-resolution, wide-area imaging applications.

Abstract: An orthoscopic, apochromatic lens is suitable for deployment such as on aerial platforms provides distortion less than 0.2% over a full field of view of more than 60° with F# less than 6.5 and focal length greater than 3″, and in embodiments greater than 5″. Embodiments are apochromatic from 500 to 950 nm to within 7 microns. Embodiments have an overall length of less than 7″. The lens includes five optical groups with an aperture stop between the second and third groups. The optical groups have one, one, two, one and one optical element each, as ordered from the object to the image plane, and have positive, negative, positive, positive, and negative optical powers, respectively. Embodiments are telephoto. In embodiments the focal length is temperature invariant within 0.0015 inches from 0° C. to 40° C.
