Patent number: 11953667Abstract: A device by which the magnification stages of a magnification selector based on Galilean telescope systems can be adjusted by a motor. The magnification selector has a sensor that transmits the currently magnification stage to a control unit; in the control unit, an assignment of the magnification stages present on the magnification selector to a sequence of the magnification stages, organized based on size, is stored. For the user, there are operating elements connected to the control unit for selecting a magnification stage. In order to set the magnification stage selected by the user via the operating elements, the magnification selector has an actuator, which is connected to the control unit to receive appropriate control signals. Although provided in particular for slit lamps and surgical microscopes having eyepieces, the solution can also be applied in other ophthalmological devices or devices from other technical fields.Type: GrantFiled: August 23, 2018Date of Patent: April 9, 2024Assignee: Carl Zeiss Meditec AGInventors: David Golz, Dietrich Martin, Ingo Koschmieder

Patent number: 11513331Abstract: A device for outcoupling a portion of the radiation of an observation beam path of a binocular eyepiece for documentation or co-observation that is freely selectable at any time. For the outcoupling, a rotatable supporting unit, the axis of rotation of which is parallel to the axes of the observation beam paths, is arranged in the housing having the binocular eyepiece. Three optical elements are arranged on this supporting unit such that an outer and the middle optical element and, after rotation of the supporting unit, the middle and the other outer optical element are each located in one of the observation beam paths. Here, the two outer optical elements have a beam-splitting effect and outcouple a portion of the observation radiation into a common documentation beam path.Type: GrantFiled: September 11, 2018Date of Patent: November 29, 2022Assignee: Carl Zeiss Meditec AGInventors: Ingo Koschmieder, Dietrich Martin, Günter Link, Lothar Müller

Patent number: 8277047Abstract: Illumination unit for the generation of optical sectional images in transparent media, particularly in the eye is disclosed. In the arrangement according to the invention, the low-divergence beams emitted by a laser serving as illumination source are imaged on or in the eye under examination by a reflection element which is controllable in a defined manner and beam deflection elements present in the beam path. The optical sectional images resulting in and on the eye can be observed and/or recorded, further processed and evaluated with an image processing unit in a known manner. In the solution according to the invention, a sectional image is generated by the deliberate periodic beam deflection of a particularly fine laser beam with high depth of focus, which sectional image remains sharp through the entire dimension of the object to be examined and makes possible an improved evaluation.Type: GrantFiled: November 11, 2002Date of Patent: October 2, 2012Assignee: Carl Zeiss Meditec AGInventor: Ingo Koschmieder
