3.5-BY-7-Fingerprint-Magnifier

This two-in-one, fixed-focus Magnifier changes from 3.5X to 7X simply by lowering the smaller lens into place.

This 2.5″ (65mm) diameter and the 1″ (25mm) diameter lenses are optically ground and polished glass, providing uniform magnification, brightness, contrast, and color without significant geometric distortion.
