Abstract: The invention relates to a method for optimized setting of light power at the object plane in the case of reflected light microscopes, surgical microscopes in particular. In accordance with the invention, a check is performed as to whether or to what extent thermal danger or damage to the illuminated sections is relevant in order to regulate, in particular limit, the light output of a light source upon a threshold being reached.

Abstract: The microsurgical microscope system with a stand and with a parallelogram linkage is characterized in that a bar, which connects two substantially horizontal bars and to which the microscope is connected, also has a receiving device connected to it for accessory parts of the microscope and/or additional weights.

Abstract: The microsurgical microscope system with a stand with three parallelogram linkages and a microscope arranged thereon is characterized in that a second parallelogram linkage and a third parallelogram linkage have a common bar inclined at an angle of approximately 30° to 60° to the vertical.

Abstract: The illuminating device for a surgical microscope, with the aid of which the illumination is performed through the microscope objective (4), is defined in that the angles of the incident light (1a, 1b) with the optical axis (11) of the microscope objective (4), and also the intensity of the various light beams can be varied independently of one another with the aid of two reflecting elements (9, 10) which can be displaced independently of one another.

Abstract: The surgical microscope with a stand, the microscope having altogether up to six degrees of freedom and being fixed on the microscope mounting by means of elements of the stand which has two vertical pivoting axes and for the height adjustment a parallelogram linkage with weight compensation is distinguished by the fact that the microscope is mounted on the stand by means of a third vertical axis, a first further axis perpendicular to said third vertical axis and a second further axis perpendicular to the first further axis, the further axes being designed such that they are essentially perpendicular to the optical axis of the microscope objective and can be adjusted by motor, and the further axis that is closer to the microscope permitting a lateral pivoting of the viewing direction and the further axis that is arranged between the third vertical axis and the further axis that is closer to the microscope permitting a pivoting of the viewing direction forward/backward or upward/downward.

Abstract: The endomicroscope system includes an operation microscope and a flexible image transmission system and is distinguished by the fact that the flexible image transmission system ends in an imaging device (2), which is arranged between the objective lens (10) and the object plane of the operation microscope (1) and can be removed from the beam path.

Abstract: An optical system for a stereoscopic surgical microscope for interchanging two light rays parallel to the optical centre axis with simultaneous image reversion for both rays without parallel offset of the emerging pair of rays with respect to the entering pair of rays, comprising elements reflecting on one side and two elements reflecting in parallel on both sides, all of which are arranged in a plane perpendicular to the optical axis. Each of the elements reflecting on both sides reflects the incident ray with its front side via the elements reflecting on one side to the rear side of the respectively other elements reflecting on both sides. All the optical elements are configured as flat, superficially mirror-coated mirrors, so that their substrate lies completely outside the path of rays.
