ABSTRACT:
The invention contemplates use of a bayonet mount for microscope objectives, instead of the customary threaded mounting of such objectives. The bayonet mount is characterized by the objective (1) having a centering cone (3) which engages and precisely centers in a conical opening (10) in the turret of the microscope. The structure not only permits rapid changing of the objective, but the thus-mounted objective always assumes the same accurately centered angular position with respect to the microscope housing.
Each objective can therefore carry exposed coded indicia, containing technical data concerning the objective, and the coding may be read by a reading device which is fixed with respect to the microscope housing. The code which is read for the objective indexed into working position may be used for aperture control in the microscope.
