Abstract

The ophthalmologic microscope comprises a first component including a base and a stage, a second component including a pivotal arm and a microscope device, and a third component including a pivotal arm and a light source. The various components are mutually pivotal at a hinge. An electronically controlled brake and a position sensor are incorporated into the hinge. The brake controller of the microscope is adapted to interrupt a manual mutual displacement of the components in response to a signal from the position sensor in order to assist the user in properly aligning the components.
