This study proves feasibility and establishes preliminary design for a nonlinear lens capable of imaging in the 8-14 micron spectral region. When coupled to existing linear infrared scanners this lens can fully support human vision in both field of view 160 deg and resolution 1 cyclemilliradian. This capability is achieved through optical distortion which causes focal length to vary by a ratio of 501 from an axis 2 inches to 80 deg field angles .04 inch. The lens has an F number of two and a clear aperture of eight inches in diameter. Author
