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.

Abstract: The invention relates to a microscope, comprising a stage (13); an x motor, a y motor, and a z axis focusing driving mechanism that drive the stage to move along left-right, front-rear, and up-down directions respectively; a controller; at least one knob (3) which is operatively coupled to the x motor and/or y motor or the z axis focusing driving mechanism selectively by means of the controller to control operation of the coupled motor or the coupled z axis focusing driving mechanism; and at least one button (4, 5) which is coupled to the controller in communication and sends to the controller a button signal indicating that the button has been triggered by operation of the microscope user.

Abstract: The invention is directed to a light microscope with an external power supply unit. The microscope according to the invention has a receptacle for the external power supply unit in which it can be fastened in a removable manner. This receptacle is advantageously formed as a cutout in the microscope stand so that the power supply unit adapts to the outer shape of the microscope when seated in the receptacle.

Abstract: The invention is directed to a light microscope with a display which is suitable for use particularly in lecture rooms or dissection rooms. By an integrated, large display of the viewing conditions, e.g., lamp voltage, selected objective, etc., that can be viewed from a distance, the actual state of the adjusted conditions can be determined from any position within a classroom or laboratory room.

Abstract: A reflector turret for an inverted microscope, having a cover which is water-tight at least at the top and substantially light-tight outside the microscope beam path, wherein a protective glass is fitted into the upper part of the cover in the light path so as to be tight against liquid, and the protective glass is removable and/or exchangeable.

Abstract: The invention relates to a changeover system for optical components such as filters, reflectors, polarizers and lens systems in optical equipment, particularly microscopes, a so-called reflector revolving nosepiece. The elements carrying the optical components, the so-called reflector blocks, are held by spring force against precision stops on the revolving nosepiece. For this purpose, the reflector blocks have lateral flanges that are respectively held against precision stop surfaces on the revolving nosepiece, by two respective leaf springs. The direction of the spring forces is mutually inclined, so that an outer edge of the flange is pressed into the interior edge formed on the revolver by two mutually perpendicular surfaces. The invention makes possible a rapid and simple fitting and changeover of reflector blocks without the use of tools.
