Abstract

Splitting an optical system into two parts separated by an intermediate image is a very fruitful method for designing ultra-wide-angle, ultra-large-aperture lenses. This technique is illustrated by several designs having an extremely large optical invariant. These designs are further characterized by low geometrical distortion and remarkably uniform relative illumination.
