Correction in the Bausch & Lomb 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.
