Double Gauss Design

An imaging lens design that employs low f/# imaging lenses that provide superior overall correction and produce less distortion than standard fixed focal length lenses. However, this design can be subject to residual oblique spherical aberration. Two Gauss lenses, each comprised of a negative doublet and a positive singlet, are situated symmetrically in the design. Double Gauss lenses are commonly used in machine vision applications.
