Abstract
A low distortion lens suited for a wide variety of applications uses a double plane symmetry lens as part of a lens system to permit aberration correction to be optimized in the field of view of an associated sensor. Wide angle, Kepler telescopic and Galileo telescopic designs can be implemented. The design can be implemented using existing manufacturing techniques.
