In terms of performance, both the Hastings and the Coddington Magnifiers are second to none. Correction in the Coddington magnifiers is achieved through the use of a single thick lens with a central groove diaphragm. This provides for sharp, crisp images.
The Coddington Magnifier is available in 10x, 14x and 20x. The swing-away, nickel-plated case protects the lens and serves as a handle.
A little trivia ... "Coddington" Magnifiers got their name from their British inventor, Henry Coddington.
