Zeiss Aplana Tabletop Achromatic Folding Magnifier 3x/6x/9x

Magnification: 9x (3x and 6x combined) Weight: 30g Lens size: 22mm Lens type: Achromatic lens High-quality glass lenses minimize optical noise, such as image distortion and chromatic aberration, across the entire field of view. Anti-reflective coating is gentle on the eyes, reducing eye fatigue even during extended work. The D36 features two achromatic lenses: 3x and 6x, which, when used alone, provide three magnifications (9x). The large 22mm lens diameter provides excellent viewing. This high-performance magnifier, made possible only by Zeiss, the world's largest manufacturer of camera lenses and microscopes, offers a truly remarkable difference. *What is an achromatic lens? Because light has different refractive indices depending on its wavelength, this lens corrects for focal misalignment by cementing two lenses with different refractive indices and chromatic dispersion together.
