摘要: A modular compound lens (300) comprises an elementary unit with five powered optical elements (302, 304, 308, 312, 314) capable of imaging a field of view of approximately 100 degrees with an F-number of 1.7. The compound lens (300) exhibits image distortion of no more than 10% and a nearly diffraction-limited modulation transfer function (MTF) of up to 100 line pairs per millimeter. Additional optical components can be added to the compound lens (300) to widen the field of view as desired without changing the F-number and without significant increase in image aberrations.
