UNIVERSAL SIMPLE AND COMPOUND MICROSCOPE

MAKER: CHARLES CHEVALIER

c. 1840

SIGNED: 'Microscope Achromatique Universel, de, Charles Chevalier, Ingénieur Opticien, Palais Royal 163 Paris'

This page illustrates the arm used with the Chevalier Universal Microscope when using simple lenses. The arm for the simple lenses was missing from my instrument. I fabricated a replica using examples of the arm from two other similar instruments. This was not a simple process and required several hours of work. I did most of this work on a Sherline table-top milling machine using end-mills. A rotary table was used for cutting the ring, both the inside and the outside. My mill does not have motor drives for the lead screws nor does it have a digital readout, which made the project even more tedious. The steel insert was made on my table top Sherline lathe.
