摘要:
A light trap, a device for coupling a first beam path to a second beam path, and an illumination device for an optical observation device, as well as an optical observation device. The light trap is for eliminating or preventing stray light, e.g., in the form of scattered light. In order to be able to further improve the elimination of disruptive stray light in the form of scattered light, the light trap is configured in a special way. It has a filter element, particularly a neutral filter element, which is characterized in that an incident light face of the filter element has a concave radius, whereby the incident light face has a specific curvature.

First of all, the present invention relates to a light trap (20) for eliminating or preventing stray light, e.g., in the form of scattered light. In addition, the invention relates to a device (10) for coupling a first beam path (34) to a second beam path (42)*. Finally, the invention also relates to an illumination device (30) for an optical observation device as well as an optical observation device. In order to be able to further improve the elimination of disruptive stray light in the form of scattered light, light trap (20) is configured in a special way. It has a filter element (21), particularly a neutral filter element, which is characterized in that incident light face (22) of filter element (21) has a concave radius, whereby incident light face (22) has a specific curvature. * sic; second beam path (41)?—Trans.

A light source arrangement (101) for an illumination device of a medical-optical observation apparatus has an illumination light source (7) and an illumination optical unit (15) for illuminating an observation object (23) with illumination light from the illumination light source (7). The light source arrangement (101) has at least one luminescence emitter (3) as light source and an imaging optical unit (105) that generates an image (7) of the at least one luminescence emitter (3) with a defined magnification scale, which image forms the illumination light source for the illumination device.

A camera holder (3) is provided for fixing a camera (11) or a camcorder to an optical observation device. The holder (3) has a variable-length sleeve (13) with a first end configured to receive the camera objective and a second end configured to secure the sleeve (13) relative to the optical observation device. The holder (3) also has an adjusting device (19) fixed to the sleeve (13). The adjusting device (19) has a pin for connection with a stand mating thread of a camera (11) and is configured to compensate for an offset between the stand mating thread and the camera objective. The adjusting device (19) enables the camera (11) to be positioned with respect to the sleeve and the optical observation device.

摘要:
A tube for an optical observation device, in particular for a microscope, with a viewing level that is linearly variable in length and/or height, wherein the tube has an optical light path, in which at least two optical elements are disposed, for example, deflecting elements. The tube can be designed, for example, as a swing-in tube, with a base part, wherein a deflecting element is disposed in the base part so that it can rotate around an axis of rotation, and with an eyepiece support that can swing in relative to the base part, wherein a deflecting element is disposed in the eyepiece support so that it can rotate around an axis of rotation. The optical elements may be disposed so that they can move independently of one another in the optical light path.

A tube (10) for an optical observation device, in particular for a microscope, is described, with a viewing level that is linearly variable in length and/or height, wherein the tube (10) has an optical light path, in which at least two optical elements (23, 34) are disposed, for example, deflecting elements. The tube can be designed, for example, as a swing-in tube, with a base part (20), wherein a deflecting element (23) is disposed in base part (20) so that it can rotate around an axis of rotation (22), and with an eyepiece support (30) that can swing in relative to base part (20), wherein a deflecting element (34) is disposed in eyepiece support (30) so that it can rotate around an axis of rotation (33). In order to make possible a large swinging range, for which different viewing positions or structural lengths and structural heights of the swing-in tube (10) can be realized simultaneously for any viewing angle, it is proposed according to the invention that the optical elements (23, 34) are disposed so that they can move independently of one another in the optical light path. For example, deflecting elements (23, 34) can be disposed in a swing-in tube, so that they can rotate and/or be displaced independently of one another.
