Featuring a unique dual lens system, the LumiLoupe Plus 6x Focusing Stand Magnifier from Carson is able to achieve a high magnification with minimal distortion for clearer viewing of close-up subjects. The two-element design benefits viewing differently-sized subjects from varying distances, and the controllable focus allows you to refine sharpness for greater clarity. The 1.75" lens diameter offers a wide viewing area and the 4.5" base diameter is well suited to a variety of subjects, including coins, currency, film negatives, stamps, jewelry, miniatures, and a variety of other objects.
