Peak 1985 Steinheil System Magnifier
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.
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
futhermore, the naked lens surfaces of soft flint glass are liable to get
scratches in daily use.
