Abstract

A microscope, including an x motor, a y motor, and a z axis focusing driving mechanism that drive a stage to move; at least one knob operatively coupled to the x motor or y motor or the z axis focusing driving mechanism selectively via a controller; and at least one button coupled to the controller in communication. The controller is configured to disconnect a normal operative coupling between the knob and the z axis focusing driving mechanism and establish an operative coupling between the knob and the x motor or y motor when receiving a predetermined button signal, and restore the normal operative coupling between the knob and the z axis focusing driving mechanism and disconnect the operative coupling between the knob and the x motor or y motor when no longer receiving the predetermined button signal or when receiving a next button signal.
