Abstract: A microscope for examining a sample includes a microscope stage for receiving the sample to be examined and further includes a microscope housing enclosing the microscope stage. The microscope housing includes a first access door and a second access door, whereby both the first access door and the second access door, upon opening, provide different ways of access to the microscope stage.

Abstract: A laboratory system includes: a laboratory device on a table surface of a laboratory bench, the laboratory bench having at least one receiving section below the table surface, which at least one receiving section receives at least one fluid reservoir which is connected to the laboratory device. In an embodiment, the laboratory device includes a climate chamber and/or an incubation system, and the laboratory system further includes a first fluid supply system that supplies at least one fluid to the climate chamber and/or the incubation system, the first fluid supply system being connected to the at least one fluid reservoir in which the at least one fluid is storable.

Abstract: An optical system is described for merging a first and a second partial image beam emanating from a specimen into a resultant image beam allowing modification of the areal proportion of the respective first or second partial image beam in the resultant image beam. A stop arrangement comprises at least a first and a second movable stop element each comprising at least one stop region adapted to be brought into a working position with the first or second partial image beam. Movably arranged connecting means for connecting the two stop elements are provided to modify the respective areal proportions of the partial image beams in the resultant image beam by movement of the connecting means.

Abstract: An illumination device in a microscope includes multiple light sources arranged on a mirror housing. A mirror is provided which is rotatably or displaceably arranged in the mirror housing for selectably switching each of the light sources into an illumination beam path. At least one drive system is provided for rotating or displacing the mirror so as to switch one of the light sources at a time into the illumination beam path.

Abstract: An indexable microscope is described, that comprises a microscope stand and an optical beam path, having a plurality of optical components that are switchable into and out of the beam path, which are arranged on at least two independent mechanical assemblies to be indexed separately and are switchable selectably into and out of the beam path by indexing the respective assembly. According to the present invention, a space-saving and flexible arrangement of the separately indexable assemblies having the optical components is achieved in that a common central receiving plate is provided, on the upper side and the lower side of which at least one of the assemblies is respectively arranged. Configuration of the assemblies as rotary disks permits very flexible arrangements which allow both manual and motorized actuation of the indexing of the assemblies.

Abstract: A device for adjusting the height of an arrangement 2 relative to a mounting surface 3 is disclosed. Height-adjusting device 1 is designed so that during height adjustment no friction takes place as a result of rotation of the contact sites of the height-adjusting devices 1 with the mounting surface 3. Height-adjusting device 1 consists of a rotary wheel 8, a socket 9 and a foot 11. The height adjustment of rotary wheel 8 and foot 11 relative to the stationary socket 9 occurs in telescopic manner. Height-adjusting device 1 is designed so that the foot 11 undergoes a displacement twice as large as does rotary wheel 8. A support (30) for an optical system is provided with several height-adjusting devices 1 connected with the bottom 5 of a base 31 of the support 30.

Abstract: A microscope (1) having a holding apparatus, insertable reversibly into the microscope (1), for interchangeable optical components is described. According to the present invention, the holding apparatus is embodied as a pivoting drawer (10) that is arranged pivotably in and out about a pivot axis. During exchange or insertion of optical components, the pivoting drawer (10) always remains connected to the microscope stand (2) even in the pivoted-out state. It is guided while being pivoted in, so that jamming, as in the case of plug-in modules previously known from the existing art, is avoided.
