Abstract: A stereo video microscope system (10), comprising: a stereo video microscope (11) having two output channels for providing stereo image data and including an internal lighting; a display unit (14) having two input channels for receiving and displaying stereo image data; and a control unit operably connected to the stereo video microscope (11) and the display unit (14) such that the control unit can control the operation of the stereo video microscope (11) and the display unit (14) and the flow of stereo image data between the two output channels of the stereo video microscope (11) and the two input channels of the display unit (14). In one embodiment the control unit is configured for performing an image rotation and/or exchanging the output channels such that the stereo image is always upright.

Abstract: A zoom system (10) for an optical stereo device is provided. The zoom system (10) comprises a front plate (30) and a lens plate (60) disposed in a fixed spatial relationship and defining two optical paths within the zoom system (10). The zoom system further comprises a zoom plate (40) having two lens assemblies (45a, 45b), wherein the zoom plate (40) is disposed between the front plate (30) and the lens plate (60), and a compensation plate (50), wherein the compensation plate (50) is disposed between the zoom plate (40) and the lens plate (60).

Abstract: A support system (10) and method for the viewer-dependent positioning and alignment of a monitor (20) is disclosed. The support system (10) comprises a central support column (14), a first arm (16) having an adjustable length L, wherein the first arm (16) is rotatably connected at its proximal end to the central support column (14) and is pivotally connected at its distal end to the monitor (20), a second arm (18), wherein the second arm (18) is connected at its distal end to a camera (50), and control means for positioning and aligning the monitor (20) such that irrespective of the angular position of the viewer (i) the monitor (20) is positioned along the line of sight of the viewer pointing towards a reference position, (ii) the distance from the monitor (20) to the viewer (40) is held constant, and (iii) the monitor (20) is at a right angle with respect to the line of sight of the viewer (40) pointing towards a reference position.

Abstract: The present invention relates to optical instruments, in particular to magnification loupes, stereo-magnification loupes and magnification viewers, such as those worn by dentists and surgeons.

Abstract: A system and a method for displaying a first image of an object of interest from a first source and a second image of an object of interest from a second source in an overlaying relationship are described. The system (10) comprises a display unit (12) having two input channels for receiving and displaying the first image and the second image, and a control unit (14) configured to supply one input channel of the display unit (12) with the first image from a first source and the other input channel of the display unit (12) with the second image from a different second source, such that said first and second image can be displayed in an overlaying relationship by the display unit (12). Preferably, the display unit (12) is an auto-stereoscopic or a stereoscopic monitor.

Abstract: An eyewear is described comprising two segmented look-through elements each comprising an upper and a lower segment, wherein the upper segments are provided with means to selectively direct an image to the left and/or to the right eye. Preferably, said means are configured as LCD shutter glasses, optically polarized glasses, red and green glasses or as display units. The two lower segments of the two look-through elements are preferably configured as normal glasses including a pair of magnifying glasses. The eyewear can be used in a variety of environments including, in particular, the medical field and industrial processes. Furthermore, a system is described comprising such an eyewear as well as a display device to be looked at by means of said eyewear.

Abstract: The invention concerns a method for operating an optical system (1) as well as an optical system. In the method an object of study is spatially imaged in an image plane using a microscope (2) comprised in the optical system (1), wherein the microscope (2) comprises at least one lens system which is assigned to a respective optical path (3, 4) and a collecting lens arrangement (11) which is assigned to the optical paths or optical paths (3, 4), wherein the at least one lens system comprises a first lens arrangement (3a; 4a) and a second lens arrangement (3b; 4b) positioned between the first lens arrangement (3a; 4a) and the collecting lens arrangement (11).
