Patent number: 11573427Abstract: The invention relates to an optical viewing system and a method of aligning an eyepiece image and an image of a camera that is part of an optical viewing system, which enables both the observation of an optical image with one eye and the capturing of the optical image with the camera. The optical viewing system comprises an optical device, an eyepiece with field diaphragm, a beam splitter, and a camera with image capturing level. According to the method, an image mask is adjusted to the eyepiece image for the camera image of the camera as follows: The eyepiece is illuminated from its side facing away from the optical device, and light passes through the eyepiece to the beam splitter so that the light is partially reflected from the first semi-reflective surface to the second semi-reflective surface and from the second semi-reflective surface to the camera, resulting in the camera capturing an image of the field diaphragm of the eyepiece as a light spot on the image capturing level.Type: GrantFiled: March 9, 2021Date of Patent: February 7, 2023Assignee: XION GMBHInventor: Holger Müller

Patent number: 10682039Abstract: A video endoscopic device has a camera head and two parallel optical arrangements, each with optical components, arranged coaxially with one another along a common first optical axis of the optical components of a respective optical arrangement and in the interior of an endoscope shaft. The optical components transmit an optical image from a distal end of the respective optical arrangement to a proximal end of the respective optical arrangement. The camera head contains at least one image sensor comprising a recording plane and at least two projection objectives, each having a second optical axis and arranged to project an image onto the image sensor. The optical arrangements comprise a collimating optical unit for generating an at least approximately parallel beam path at the outlet of the respective optical arrangement. The respective collimating optical unit has a third optical axis arranged coaxially with the optical components of the optical arrangements.Type: GrantFiled: May 22, 2014Date of Patent: June 16, 2020Assignee: XION GMBHInventors: Holger Muller, Alexander Kliem

Patent number: 9962064Abstract: An adapter for the releasable and relockable coupling of an endoscope with a camera head has an inner wall and an outer wall that are connected with one another via a connecting wall extending between the inner wall and outer wall at or near their first axial ends, and which inner wall and outer wall are arranged with at least a lateral separation from one another, so that an open clearance results between the inner wall and outer wall on a second axial side that is situated opposite the first axial ends. Furthermore, the adapter comprises a coupling wall that seals a clearance enclosed by the inner wall at or near a second axial end of the inner wall, such that the clearance that is enclosed by the inner wall is open at a first axial side that is situated opposite the second axial end of the inner wall.Type: GrantFiled: November 3, 2015Date of Patent: May 8, 2018Assignee: XION GMBHInventors: Helmut Laser, Holger Muller
