ABSTRACT:
A gem microscope includes a base structure that supports the microscope stage, focus column, and optical head. The base structure includes a lower component that receives a power cord; the lower component and the power cord remain stationary when the gem microscope is in use. The base structure also includes an upper component rotatably coupled to the lower component. The upper component can rotate around the lower component to enable convenient sharing of the gem microscope by a number of users. The base structure includes an electrical coupler assembly that maintains an electrical connection (for the gem microscope power supplies) throughout rotation of the gem microscope.
