Patent number: 9885858Abstract: A surgical microscopy system includes a surgical microscope with a control device and with focusable imaging optics for observing an operation field. The microscope is arranged on a stand with a base unit. The stand is embodied with linear drives and/or rotary joints in such a way that the surgical microscope is displaceable along three direction axes and rotatable about three axes of rotation relative to the base unit. For renewed focusing to a desired point, position and/or rotational sensors are assigned to each of the drives and/or joints for each of the direction axes and position and/or rotary angle sensors are assigned to each of the drives and/or joints for each of the axes of rotation and a focusing sensor for a focal point is assigned to the focusing imaging optics. A position and alignment of the microscope relative to the base unit and the focal point are storable.Type: GrantFiled: May 27, 2015Date of Patent: February 6, 2018Assignee: Carl Zeiss Meditec AGInventors: Stefan Ernsperger, Hans-Juergen Seitz

Patent number: 9829692Abstract: An optical observation unit (1) has an illumination apparatus (43) for illuminating an observation object (3). The illumination apparatus (43, 143) has a light source (45) emitting illumination light with a first color temperature, and a spectral filter (49) that can be inserted in the illumination beam path. The spectral filter (49) converts the illumination light with the first color temperature into illumination light with a second color temperature. The illumination apparatus further has an attenuator (51) that can be inserted in the illumination beam path in place of the spectral filter (49) and has a transmission characteristic that leads to an intensity reduction of the illumination light with the first color temperature that corresponds to the intensity reduction of the illumination light with the second color temperature by way of the spectral filter (49).Type: GrantFiled: April 14, 2010Date of Patent: November 28, 2017Assignee: CARL ZEISS MEDITEC AGInventors: Peter Reimer, Thomas Kratzer, Stefan Ernsperger, Bruno Stich

Patent number: 9232983Abstract: A method is disclosed for determining an illumination beam dose in surgical field illumination. Said method comprises the following steps: at least one actual illumination-relevant value is sensed; and an illumination beam dose is calculated from said sensed actual value. Sensing of the actual illumination-relevant value includes sensing of a value of at least one adjustable parameter of an illumination device. Furthermore, simulated dose characteristics associated with the adjustable parameter are selected, at least one simulated dose value is calculated taking into account the value of the adjustable parameter and the associated simulated dose characteristics, and the illumination beam dose is calculated taking into account the at least one simulated dose value. Also disclosed are an apparatus, a computer program product, and a surgical microscope for carrying out said method.Type: GrantFiled: February 4, 2009Date of Patent: January 12, 2016Assignee: Carl Zeiss Meditec AGInventors: Stefan Ernsperger, Peter Reimer

Patent number: 8976238Abstract: An optical observation apparatus has an optical image channel for viewing optical field-of-view images, a processing unit to generate a first electronic insertion image via a first electronic image channel, and a data insertion image projector for generating an optical insertion image from the first electronic insertion image and inserting that image into the optical field-of-view image. An acquisition device acquires the optical field-of-view image without the optical insertion image inserted by the data insertion image projector. A second electronic image channel has a superimposition module, that superimposes the electronic field-of-view image with an electronic insertion image and provides the superimposed images via the second electronic image channel. The processing unit generates a second electronic insertion image, provides available display data elements, and makes it possible to assemble the electronic insertion images and assign them to different electronic image channels.Type: GrantFiled: June 9, 2009Date of Patent: March 10, 2015Assignee: Carl Zeiss Meditec AGInventors: Stefan Ernsperger, Gerhard Gaida

Patent number: 6177988Abstract: An arrangement for measuring the power or energy of optical radiation of radiation sources, especially laser radiation is disclosed. It comprises a module defining an open or at least partially closed hollow space, wherein the inner walls or outer walls of the module are entirely or partially occupied by detectors for generating measurement signals which are proportional to the measured parameters of the radiation sources. The detectors are connected together in such a way that their generated measurement signals are further processed to form at least one resultant sum signal or the detectors are connected to a downstream processing device to form at least one resultant sum signal. This at least one resultant sum signal is relatively independent from the position, arrangement and radiating characteristic of the examined radiation source in the module. At least one opening or guide-through is provided in the module for inserting the radiation source to be examined.Type: GrantFiled: September 17, 1999Date of Patent: January 23, 2001Assignee: Carl Zeiss Jena GmbHInventors: Steffen Dubnack, Stefan Ernsperger, Frank Luemkemann, Heino Weigand
