The minimum thickness of Fresnel magnifying glass made of PVC can be between 0.45mm and 0.90mm. Different from ordinary magnifying glass, its surface is covered with tiny stripes, and its vortex like stripes contain many convex lenses (referred to as circular rings), so that the light passing through it bends to produce diffraction phenomenon, so as to form an enlarged image. Fresnel lens is characterized by higher brightness than ordinary lens, flat surface and large radiation area. The diameter of ordinary concave convex lens is very limited, and Fresnel plays a good role in the field of magnifying glass, which can not be achieved by ordinary lens. Moreover, the thickness of the Fresnel magnifying glass is only 0.45mm. In fact, the main function of the portable belt is to reduce the weight and volume of the ordinary plexiglass and glass magnifying glass produced by the traditional magnifying glass.
