PEAK STEINHEIL SYSTEM LUPE

The Steinheil type lens is composed by a dual-convex lens with strong curvatures made of crown glass and two negative "meniscus lenses" of "flint glass" cemented together.

A lens of this kind is often used also as a handable mono-ocular lens, thanks to its support, its excellent chromatic correction and its reasonably wide field of view.

The new Peak Steinheil Lupe series, consisting of mono-ocular lens with a magnifying power respectively of 7X, 10X, 14X and 20X , have been designed also to put the in the pocket. The cemented lens block is mounted on a light weight cylinder made of black plastics, and a sliding frame of the same material covers and protects both lens surfaces from dust and mechanical damages. In the working condition, the frame is slidden to form a convenient handle for mounting the loupe. The new series of loupes is very useful for fans of gemmology.
