Specifications

Stand or table magnifiers are easily-to-use magnifiers that stay upon a tabletop
The maginfiers are made from either glass or plstic lenses

An achromatic lens or achromat – like the PB.5039 – is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths into focus in the same plane

The achromatic triplet, which is composed of three individual lenses made from glasses with different amounts of dispersion. The lens elements are mounted next to each other and provides the ultimate in distortion-free, color-correct viewing. The triple lens system is made up of two concave meniscus elements cemented to a double convex lens
