  Coddington Microscope

  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.

  Coddington Microscope

  The Coddington lens was invented in 1829 by Henry Coddington. This microscope is made from brass and wood and contains a single lens with two curved sides and a groove cut around the middle of the lens which acts as a lens stop. The microscope offers a clear image from 1 inch away from the front objective lens. This microscope was used in the field by botanists and naturalists due to its small size, good magnification and portability.
