Title
Charles Baker Polarizing Microscope
Description
The compound microscope has a double nose-piece which holds two objectives that can be rotated when needed. The monocular microscope is made from brass and japanned black cast iron. The horseshoe-shaped base and limb are japanned and connected via a trunnion joint that allows the microscope to be angled for observation. The coarse focus functions via a rack and pinion mechanism which is operated by a thumbscrew on the side of the microscope. Fine focus is controlled by the thumbscrew on the side of the pillar. The circular stage is fixed with stage clips that secure the specimen for observation. The outside of the stage has markings of measurement that range from 10 to 360. Beneath the stage is a polarizer which can be adjusted by rotating it. The microscope comes with a wooden, fitted case with compartments to secure the microscope. The case is secured via a lock on the door.
