Abstract: An optical detection device for validating bank rates has several input apertures, an imaging device (12), a diffraction grating (15.1, 15.2, 15.3) associated with each input aperture (11.1, 11.2, 11.3) and a detection array (17). The diffraction grating (15.1, 15.2, 15.3) is rotated at angle of e.g.45 degrees relative to the orientation of the linear detection array (17). This arrangement enables the spectra of multiple points to be measured simultaneously. The angle of rotation, the pitch of the apertures (11.1, 11.2, 11.3) and a pitch of the diffraction grating (15.1, 15.2, 15,3) are selected in such a way that the spectra of sad multiple points are contiguously mapped onto the detection array (17) has a single linear array of color sensitive detection pixels. The acxis of the linear array is offset with respect to an optical axis (7) of the optical detection device.

Abstract: Bei einem optischen Spektrometer (1) mit einem Beugungsgitter (2), mit einem das einfallende Licht (5) auf das Beugungsgitter (2) abbildenden Eingangsspalt (4), mit einem das am Beugungsgitter (2) gebeugte Licht wellenlängenselektierenden Ausgangsspalt (8) und mit einer Einrichtung zum Variieren der Bandbreite des Spektrometers (1) ist als Einrichtung zum Variieren der Bandbreite ein optisches Element (11), z.B. eine variable Blende, im Strahlengang zwischen dem Eingangsspalt (4) und dem wellenlängenselektierenden Ausgangsspalt (8) angeordnet, das die Fleckgröße des gebeugten Lichts am Ausgangsspalt verändert. Die Bandbreite der durch den Ausgangsspalt durchgelassenen Wellenlängenanteile, d.h. die Bandbreite des Spektrometers, wird durch unterschiedliche spektrale Auflösungen des Beugungsgitters variiert.

Abstract: The invention relates to a device for simultaneously detecting several spectral ranges of a light beam (1), especially for detecting the light beam (1) of a laser scanner (2) in the detection beam path of a confocal microscope. In order to realize a simple construction having a small overall height while avoiding the defocusing effect, the invention is characterized by having an arrangement (3) provided for a spectral fanning out of the light beam (1) and by having an arrangement (4) for splitting the fanned out beam (5) out of the dispersion plane (6) and into spectral ranges (7, 8, 9). Afterwards, a subsequent detection of the fanned out spectral ranges (7, 8, 9) is carried out.

Abstract: The invention relates to an arrangement for increasing local spectral resolution in spectrometers for spectral analysis of emissions and absorptions, whereby receiver arrays are used for reception purposes. According to the invention, a receiver array, an image forming dispersive grid and a first slotted diaphragm (10) are assembled and rigidly connected to each inside the housing of the spectrometer. The first slotted diaphragm (10) is provided with n slits (11a...n). A second mobile slotted diaphragm (12) is provided with a single slit (12a) and is assigned to the first slotted diaphragm (10) whereby the slits (11a...n) of the first diaphragm (10) can be adjusted successively, one by one, and placed into a state enabling radiation to pass through. An adjustment and signal processing device is also provided so that the respective shifting states of the second diaphragm (12) can be regulated and the accompanying spectra can be picked up from the receiver array.

Abstract: For exact positioning of optical elements, a spectrometer is provided with a holder which is constructed using plates having a sector of circle shape and a side wall portion comprising a cylindrical surface portion. The cylindrical surface portion is provided with an exactly circular abutment face in which an entrance slot and an exit slot are provided. Relative to this abutment face, an entrance slit and an exit slit can be extremely exactly positioned with respect to one another along an exact circle. The holder is preferably constructed using two axially stacked compartments, in a cylindrical surface portion of which the slot or slots is/are provided between the compartments.

Abstract: A microscopic spectrometer is described in which the light from a light source (1) (3) is incident upon a sample (2) and the light, which has been reflected by or transmitted through said sample (2) is subjected to a spectrometric measurement after having passed an object lens.

Rejoining means (16-19) for rejoining the light passing along said two branched optical paths (a, b) and positioned behind the respective image planes (4a, 4b) of said paths (a, b) are used in order to observe an image obtained by synthesizing images at their respective image planes (4a, 4b).
