Microscope for a Solar and Stereopticon Combination, c. 1885
Pat. March 13, 1883
The following was extracted from The
Monthly Microscopeical Journal, Vol. VI,
1885
The Mcintosh Galvanic
Company of Chicago, have a large exhibit of their
manufactures, including Dr. Mcintosh's projection
microscope. The accompanying cuts give an idea of the
arrangement of parts, and of the appearance of the
instrument when arranged as an ordinary stand. Dr.
Mcintosh has spent most of the winter in New Orleans
and has had a place fitted up in the space occupied
by his exhibit in which to show his instrument. I
spent a pleasant hour with him, and came away with an
impression that the resources and adaptability of
projection were not fully comprehended as yet by
microscopists. For the making of drawings it is
greatly to be preferred to the camera lucida in any
form, while for continuous study of a preparation it
has a double advantage in giving a larger field than
can be viewed with the eve-piece, and being much less
wearisome to the eyes.
A patent covering
this microscope was issued to Dr. Lyman D.
McIntosh on March 13, 1883. The instrument has
the unique feature of not only being
ultilized as a conventional microscope, but in
addtion, the upper half can be disassembled and
reattached to a projector or solar apparatus to
convert the instrument into a solar microscope or
stereopticon.
