Traditional, technical folding magnifiers provide the high power optics and durability to meet any industry standard. The unique bioconvex 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. The biconvex lens provides a distortion-free image with superior optics throughout the viewing field. Dual lens of 4x and 6x power provide through levels of magnification (4x, 6x, 10x).
