Practical and simple-to-use working magnifier with four lenses. The main lens, produced of acrylic resin with hard silicon coating, offers very clear and bright images. The two auxiliary lenses with magnification factors of 5x and 10x as well as a cylindrical lens can be used in addition when a higher magnification factor is required. Two folding legs allow precise adjustment of the distance. When folded together the magnifier has dimensions of only 180 x 180 x 39 mm. The lens is supplied with a plastic cover.
