Absolutely perfect lenses: All three round, achromatic PEAK work magnifiers have new achromatic optical systems, consisting of two, optically pure white glass lenses cemented to one another. Available with different three diameters and enlargement factors, these colour-corrected lenses are distinguished by their excellent correction factor, completely eliminating unsharp lines over the entire image field. The extension arm can be adjusted as required in all directions and the heavy base keeps the magnifier from tipping over even in complex positions. The solid lens frames make these achromatic working magnifiers a valuable aid in every respect. Provides valuable help for assembly, testing or restoration work. Lenses coated on both sides to prevent reflection.
