The microscope limb and base is black enameled cast iron with the tube and knobs having a bright lacquer surface finish. The microscope has a nickel plated calibrated draw-tube to extend its length. As shown in the photos with the draw-tube closed the microscope measures about 11 1/2-inches tall in the inclined position. The microscope focuses using a rack and pinion. The fine focus is by tube-mounted micrometer screw which moves the nosepiece. The swinging movement of the mirror arm will allowed oblique illumination including above-stage illumination. The mirror is double sided with plane and concave glasses.

This firm was started by two brothers Edward & Frederick Tighe. They were born in Canada to Irish parents. They emigrated to the US in the 1870's where they later set up an optical business in Detroit. The Tighe firm was active for only about 10 years. It has been said that they worked closely with the Gundlach Optical Co. of Rochester, New York.
