Though only a single lens magnifier, it's special construction, with a grooved diaphragm around its circumference, gives a good, distortion-free definition of the object being viewed.
Bausch and Lomb's Coddington Magnifiers stand second only to the Hastings triplets in their magnification quality and performance. Correction is achieved through use of a single thick lens of optical glass with a central groove diaphragm. Provides a sharp, crisp image. The protective swing-away case is nickel-plated.
