ZEISS-Pocket-magnifier-D-36

Zeiss 9X 22mm Diameter Aplanatic-achromatic 3 in 1 Pocket Magnifier Folding Loupe D36 (D24 +12DAR)

In many visual tasks where precise imaging is a must, particularly in industry, research and the handicrafts, aplanatic-achromatic magnifiers are indispensable aids. Their small dimensions also make them suitable for persons with low vision, e.g. for mobile use.  The aplanatic-achromatic pocket magnifiers are
marked with a dioptric power (D) which makes it possible to determine the respective magnification depending on the conditions of use.  These magnifiers provide images without distortion and chromatic aberration across the entire field of view. They come standard with antireflective coating.
