Description

Physical Description: This microscope is very clearly labeled as a metallurgical microscope. The material of the microscope appears to be brass with a shiny black enamel finished over the body and brass accents on the eyepiece, body tube, and fine/course adjustment knobs. The objective lens are composed of an unknown shiny metal that could possibly be aluminum or steel, and in comparably better shape than the rest of the microscope material. The lens do not appear to go up to a very high power of magnification, which is consistent with the monocular model. Based off of previous models from Wetzlar Co. that depict the objective lens in both a different material and in more complex powers, this particular part appears to be a replacement and likely not part of the original microscope material. The microscope comes in a wooden box with no other additional pieces or parts included.

Functional Description: The metallurgical microscope is intended to be used to study and inspect opaque objects by means of reflective light microscopy. These objects usually include metal, ceramic, and optical samples. Since this particular model is monocular, the functions of this microscope will be limited to a low power of magnification and only a singular eyepiece for observing.

History of the Object

This vintage metallurgical microscope sits in the chemistry office of Dr. Jaszczak--a professor and interim chair of the chemistry department. Although it is unknown how long the microscope has been in this office, it is estimated that it has been there before the minerals and material building was built in the early 90s.
Upon looking further into similar makes and models of this microscope, an exact replication could not be found. The estimated dates and materials composition were based off of documented serial numbers that could be traced back to similar makes and models of microscopes this German-based company produced.
