Abstract: An optical device for combining a first light beam and at least one second light beam includes a first beam splitting device, a second beam splitting device and a position detector. The first beam splitting device splits a first reference beam from the first light beam and a second reference beam from the second light beam. The second beam splitting device splits a third reference beam from the first light beam and a fourth reference beam from the second light beam. The position detector detects respective positions of the reference beams so as to enable a respective propagation direction and/or a respective position of the first and/or second light beams to be adjusted as a function of the detected positions of the reference beams.

Abstract: An optical component is arranged in the beam path of a scanning microscope. The optical component has a plane entrance surface through which a light beam bundle can be incoupled at an entrance angle, and a plane exit surface through which the light beam bundle can be outcoupled at an exit angle, which is different from the entrance angle. The optical component contains at least two elements that exhibit at least two different refractive indices.

Abstract: A unit (29) rotates on a first axis (27) and has first (31) and second (33) reflective surfaces fixed in place in relation to each other. The unit picks up a beam of light and passes it on to a third reflective surface (35) rotating on a second axis (37) vertical to the first axis. An Independent claim is also included for a scan microscope with a source of light for illuminating a sample/specimen.

Abstract: The invention relates to an optical system in the ray path of a confocal fluorescence microscope, comprising at least one laser light source (1, 2), a device positioned in the illuminating/detecting beam (3, 4, 5) for separating the exciting light (8) from the fluorescent light (9), an objective (10) arranged between the device and the object (7), and a detector (11) positioned downstream of the device situated in the detecting beam (5). The aim of the invention is to increase the fluorescence yield of the system while retaining its compact structure. To this end the separating device comprises a mirror (13) which is dimensioned and positioned in the illuminating and/or detecting beam (3, 4, 5) in such a way that for the dark-field illumination of the object (7) it reflects the non-expanded exciting beam arriving from the laser light source (1, 2) into the objective (10) and permits the transit of the fluorescence light (9) arriving from the object (7) in the direction of the detector (11) with full numerical aperture, the fluorescent light beam being reduced by the mirror (13) cross-section active in the detecting beam (5).

Abstract: The scanning microscope (11) has a light source (13). A mouse pointer (75) selects a lower and upper limit wavelength that defines an upper and lower limit of a lower and upper extrusion region respectively. Two adjustable stops (53, 55) blocks light components of the lower and the upper exclusion region of the detection light. A detector receives the unblocked component of the detection light. An Independent claim is also included method for scanning microscopy.

Abstract: The invention concerns a device for the confocal measuring of surfaces inside cavities of the body, specially to measure the surface profile (1) of teeth (2) in the mouth cavity. Said device has a probe (3) that can be introduced into the cavity of the body, a light source feeding the probe (3), a detector picking up a light signal (5) and a processor (6) to digitalize the detected signal transforming it into a tridimensional representation. The device is designed using a simple construction and enabling an error free scanning of the surfaces. To this end, the probe (3) is designed as a rotary scanner having at least one deviating device (7) deflecting the light beam (9) in the direction of the surface that is to be measured (1), the deviating device (7) can be positioned in another scanning axis (10) to forward the rotating light beam (9), and the detector (5) comprises a device for sequential or simultaneous scanning of several focal planes, both with regards to specular reflection and to weak scattered light or fluorescent light of the focal plane concerned.
