Abstract: In an electromotively adjustable focusing system for a microscope, a rotatable and axially moveable knob controls both the coarse and fine adjustments of the object stage. The knob is mechanically connected to a tacho-generator producing an output voltage responsive to the direction and amount of rotation of the knob. The knob is also mechanically joined to a switch, which is opened or closed by axial movement of the knob in opposite directions. The closing of the switch causes a focus control circuit to provide to the focusing motor a signal that causes coarse (rapid) focusing. When the switch is opened, however, the motor provides fine adjustment of the object stage.
