Abstract
A modular compound lens comprises an elementary unit with five powered optical elements capable of imaging a field of view of approximately 100 degrees with an F-number of 1.7. The compound lens 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 to widen the field of view as desired without changing the F-number and without significant increase in image aberrations.
