A mounting assembly for twin microscope housings to permit synchronized tilting of the microscopes including a central spindle whose outside surface is threaded to accommodate an annular collar whose inside surface has corresponding threads. A fixed bracket is mounted to the bottom of the spindle, and an adjustable bracket is mounted about the adjustable collar. A tilt bracket is pivotably mounted to the bottom bracket and slidably mounted to the adjustable bracket so that as the annular collar is rotated about the central spindle to raise and lower the adjustable bracket, the tilt bracket tilts with respect to the longitudinal axis of the spindle.

Mounting assembly for synchronized adjustment of multiple microscope

A solenoid driven magnification changer shaft for a microscope with positive index stops. The solenoid shaft that both translates and rotates when the solenoid is activated. A coupler couples the solenoid shaft to the magnification changer shaft so as to permit the coupler to rotate as a unit with the magnification changer shaft but at the same time to translate axially on the magnification changer shaft. The magnification changer shaft includes a slot extending axially from a point spaced from the end of the shaft and extending a predetermined distance. The coupler includes a recess for receiving the free end of the shaft and a transverse bore for receiving a pin which extends through the transverse bore and the slot in the magnification changer shaft. The coupler and the surrounding driver housing include cooperating index pins and a stop pin. The index pin will be driven into interfering alignment with the stop pin when the solenoid shaft translates and will interfere with the stop pin when the solenoid shaft causes the coupler to rotate to provide a positive stop for the magnification changer shaft.

Automatic magnification changer for a surgical microscope

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.
