Description:
Model No. 1985-20x, Steinheil System Lupe 20x.
PEAK OPTICAL PRODUCTS.

＊FEATURES
．The magnifier of the Steinheil type is composed of a biconvex lens with strong curvatures made of crown glass and two negative meniscus lenses of flint glass cemented on both sides of the central positive component with excellent chromatic correction and a reasonably wide field of view.

．These magnifiers of various magnifying powers have been long and widely used for preliminary inspection of microscopic specimens. These are interchangeably mounted on a special stand made for this purpose, which is equipped with a specimen table and a reflecting mirror for illuminating the specimen, just like a stand of ordinary compound microscopes.

．The magnifier of this kind is often used also as a hand loupe without the stand, because of its excellent chromatic correction and its reasonably wide field of view. In this case, however, the total weight of it including the thick metal lens-barrel is somewhat cumbersome for carrying it in one's pocket, and further, the naked lens surfaces of soft flint glass are liable to get scratches in daily use.

．The new Steinheil System Magnifier series, consisting of loupes with a magnifying power of 7x, 10x, 14x, and 20x respectively, have been designed for pocketable use these high grade magnifiers. The cemented lens block is mounted on a light weight barrel made of black plastics, and 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 gripping the loupe.

．The new series of loupes can thus be recommended to fans of Steinheil magnifiers who have been hesitating the daily use of them because of their weight and for fear of damaging them.
