Magnifying lenses represent a very wide range of goods – with diameters of lenses from 10 to 180 mm and magnification from 1,2 x to 16,0 x. Baroque magnifying lenses – gold plated with 24 carat gold – have exceptional design. Brinell measuring magnifying lenses with decimal scale are required for technical purposes. New types of magnifying lenses for cosmetic purposes and health industry are also interesting, as well as standing aplanatic magnifying lenses with lighting, which minimize eye fatigue during long-term work.
