Bausch & Lomb Professional Pocket Magnifier 10x

10x, 1” Focus, 7/8” Dia. Lens  

These pocket magnifiers from Pesola-Scales.com achieve their correction through the use of a single thick lens with a central groove diaphragm. Strong chrome-plated metal case protects the lens. The image quality of a Coddington is second only to a Hastings Triplet among magnifiers.
