Title

Coddington Microscope

Description

The microscope is gold plated on brass. 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 again minimizes spherical aberration. This allows for higher magnification than conventional magnifying glass, typically 10× up to 20×. Most single lens magnifiers are limited to 5× or so before significant distortion occurs. The drawback is that the diaphragm groove reduces the area seen through the magnifier.

Condition:

Cosmetically: Brass is darkened from age.
Optically: Some scratched on the lens.
Mechanically: The microscope is functional.
