Steinheil Magnifier, Peak Lupe 1985-1920. Magnification 20x

Peak Lupe Steinheil lens, 1985-1920, with 20x magnification. The lenses in the Steinheil lens are cemented and mounted in a lightweight plastic holder, to which a plastic case of the same material is attached to protect the lens surface from dust and scratches. When in use, the case functions as a handle for the magnifier. These lenses have a coating to prevent reflections. Also available with magnification factors of 7x, 10x, and 14x.

A Steinheil lens consists of a bi-convex glass lens crown with high curvature and two negative flint glass lenses cemented to both sides at the center of the positive element. These magnifiers with different magnification factors are popular for the preliminary examination of microscopic specimens.
