Description

An unusual late nineteenth century Coddington magnifying glass made from English brass having been professionally polished.
Excellent condition measuring 3 1/4" x 1" x 1".
A Coddington magnifier is a magnifying glass consisting of a single very thick lens with a central deep groove diaphragm at the equator, thus limiting the rays to those close to the axis, which minimizes spherical aberration. This allows for greater magnification than a conventional magnifying glass, typically 10× up to 20×.
