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. Instead of two folding legs the 2041 version is supplied with a cast aluminium base to ensure stability from all angles. The columns can be bent as required to obtain the optimum distance.
