20080198448 | FLUORESCENCE MICROSCOPE HAVING AN ILLUMINATION DEVICE - An arrangement for fluorescence microscopic examination of specimens includes: a fluorescence microscope; an illumination device that includes: a housing including an interface configured to optically couple the housing and the fluorescence microscope; a plurality of light-emitting diodes disposed in the housing; a respective collector disposed downstream of each of the light emitting diodes and configured to generate a directed light flux; and at least one dichroic splitter disposed in the housing, the at least one splitter and the light-emitting diodes being spatially disposed with respect to one another so that the directed light fluxes are combinable via the at least one splitter into a common illumination beam path directed onto the interface; and a logical control device common to the fluorescence microscope and the illumination device. | 08-21-2008 |
20090160994 | SYSTEM FOR RECORDING AND REPRESENTING IMAGES OF PREPARATIONS - A system for acquiring and displaying images of preparations is provided. The system includes a first and second illumination device, each including an illumination source defining a respective illumination beam path amid configured to emit light to illuminate the preparation. A camera and a display for displaying a portion of the preparation are further provided. The preparation can be placed on a stage that is movable in x and y coordinate directions. The frame is also provided with a combining device configured to combine the first imaging beam path and the second imaging beam path, and direct them to the camera. | 06-25-2009 |
20090195646 | MICROSCOPE COMPRISING A CAMERA CONNECTION AND A CAMERA ADAPTER - A microscope comprising a camera connection in a image beam path is suggested. A camera adapter and a camera can be adapted to the camera connection, and the microscope can be used to reproduce the image of a sample on a sensor of the camera. Imaging of the beam path in the camera adapter comprises an intermediate imaging with a pupil plane having reduced beam diameter next to the pupil plane, and at least one optical means can be inserted into the reproduction beam path in the region of the reduced beam cross-section. An optical means or an interchangeable device comprising a plurality of optical means, such as filters, plane-parallel plates or wedge plate, is integrated into the pupil plane in the camera adapter. | 08-06-2009 |
20110026112 | APPARATUS FOR POSITIONING OPTICAL COMPONENTS IN AN OPTICAL DEVICE - An apparatus for positioning optical components in an optical device and a microscope with such an apparatus are described, comprising a holding device having a plurality of receptacles on which the optical components can be fixed. A stepper motor comprises a motor shaft for rotating the holding device via a toothed belt and therefore positions the optical components. This allows to position optical components in the optical beam path with low noise and in a vibration-free manner. | 02-03-2011 |
20120134017 | DEVICE FOR FOCUSING A MICROSCOPE OBJECTIVE ON A SAMPLE - A device for focusing a microscope objective on a sample accurately with a high spatial resolution. The device has a positioning unit having a main body, an objective holder movably supported on the main body and adapted to hold the microscope objective, and an actuator for moving the objective holder along the optical axis of the microscope objective. The objective holder holds the microscope objective only at a front portion of the microscope objective facing the sample. The positioning unit includes one or more lever arms, each of which coupled at its one end via a first flexure bearing to the main body and at its other end via a second flexure bearing to the objective holder. The main body of the positioning unit is attached to a stage that carries the sample. | 05-31-2012 |
