Measuring Magnifier, 15x
A wide-field magnifying glass of 15x magnifying power, combined with a graduated measuring scale. Similar to the 7x and 10x Scale Magnifiers. However, to allow the sharp observation of the entire field of a 14mm diameter object magnified 15 times, the magnifier has been designed to correct almost perfectly the curvature of field and the lateral chromatic aberration by a combination of 4 lenses in 3 groups. Provided with measuring scale: either 20mm in length with 0.1mm divisions, or 0.5″ in length with 0.005″ divisions. Scale diameter: 26mm (1″). With case, lens cap and cloth.
