Bright field magnifier with 4x magnification. The glass lens (diameter: 75 mm) is placed directly on the item to be magnified. The plano-convex shape of the lens provides optimal light conditions and the surface below the magnifying glass appears brighter than the surrounding area. Consequently, the magnifier is perfect for reading or examining stamps or postcards. The bright field magnifying glass is handy and compact, and comes in a black velvet pouch that protects the lens from being scratched.
