Eschenbach 1184-20 Folding Magnifier 20x 17mm Achromatic Lens

The unique achromatic lens system eliminates extraneous colors. It consists of coated lenses that are cemented together using different types of glass. The result is crystal-clear optics with no color aberration. This is a 20X magnifier with a black metal lens frame and a chrome plated brass handle. 20X is very powerful, with a very small field of focus.
