Double-Gauss

From Wikipedia, the free encyclopedia

The Double-Gauss is an optical design form created in 1817 by C. F. Gauss. He designed a telescope objective consisting of a pair of meniscus elements, one positive, and one negative.

There are literally thousands of adaptations of this form, which has an apt combination of aperture, field, and design complexity. They are most commonly used in normal lenses for various formats, and allow wide apertures.
