摘要： A compact, lens suitable for airborne photography and mapping has distortion less than 0.6% and is athermal from -15°C to + 40°C. The lens is near-telecentric to less than 1 1 °, apochromatic over the wavelength range 450nm - 650nm, and has a full field of view of 60° (high quality field over 53°), The lens can be secondary color corrected. In embodiments, the focal length is 101mm and the back working distance is more than 10mm. Embodiments have a focal plane diameter of 104mm and are compatible for use with a CMOS 1.8 gigapixel multiple FPA. In embodiments, the lens comprises three groups of optical elements, with an aperture located within the second optical group. In some embodiments the first group includes two elements, the second group includes six or seven elements, and the third group include three elements, in embodiments the lens (without window) is less than 180 mm long.
