displaceable microscope objective with at least one in direction of the optical axis lens group

The invention relates to a microscope objective with at least one in direction of the optical axis of the microscope objective displaceable from at least one lens and a lens frame (13) existing lens group (3) which is connected for the purpose of displacement with an electromechanical drive. According to the invention, a microscope lens of this type comprises a a rotatory driving motion generating motor (10) and transmission members, which are designed to convert the rotational movement into a translational motion, to transmit the translational movement of the lens group (3), and at the same time to prevent twisting of the lens group (3) about the optical axis. In a preferred embodiment variant, the rotating output shaft of the motor (10) with a threaded spindle (11) is connected, the introduced with the lens barrel (13) threaded hole engages, so that the lens group (3) is moved directly translationally. Simultaneously with the engagement of the threaded spindle (11) in the lens holder (13) takes place, both the translational movement of the lens group (3) and secure the lens group (3) against rotation about the optical axis.
