Abstract: A stereo surgical microscope using a single large objective lens as the final lens of both optical paths and having changeable sets of galilean optics behind the objective lens for each optical path, the sets of galilean optics mounted on a rotary single shaft and arranged to provide magnification changes upon rotation of the shaft. A rotary solenoid connected to one end of the rotary shaft rotates the magnification changer for a different magnification upon each operation of a switch.
Abstract: A fiberoptic cable having a strain-relieved terminal end in which a length of elastomeric material is bonded to and covers the cable sheath to prevent sharp bending adjacent the terminal and a sleeve is mechanically fitted inside a rigid plastic terminal housing as an adhesive bonding adapter between said sheath and said housing.
Abstract: A fiberoptic cable assembly in which an extruded sheath for the bundle of optical fibers has latex or silicone rubber end casings for handling and strain relief that are molded directly to the cable sheath.
Abstract: A headlamp in which the optical unit receives light through a fiberoptic light conductor, the unit being readily manipulable by rotation about a vertical axis and a horizontal axis and by direct up and down vertical movement. A "joystick" projecting from the top of the optical unit provides a handle for manipulation.
Abstract: Adaptors in combination with light sources for distributing light over fiberoptic cables, each adaptor housing a fiberoptic bifurcated segment for receiving light from the source at one end and dividing between two or more separate outputs at the other end. Permanently mountable adaptors, pluggable adaptors, and adaptors with permanently affixed cables are disclosed.
