Abstract: Color measurement instrument (10) including an integrating sphere (12), a beam splitter (16), a video camera (18), and a spectrograph (20). The beam splitter (16) is aligned with the viewing port (32) of the spectrophotometer to deliver the light reflected from the sample (S) to both the video camera (18) and the spectrograph (20). The video camera (18) provides an image of the position of the sample (S) with respect to the viewing port (32) of the sphere (12), enabling the visual observation and evaluation of the sample position prior to use of the spectrophotometer.

Abstract: The invention relates to a controllable microcode line for spectrometers which in a first part (B1) is divided into n identical partial areas (21, 22). Depending on the radiation used in the spectrometer the partial areas are provided with a transparent or reflecting and a non-transparent or absorbent optical power in accordance with the code sequence in the first line of a defined diagonal matrix. At least one second area (B1) is provided for directly adjacent to the first area which has the same number n of partial areas as said first area. These partial areas have the same optical power as the partial areas of the first area and a fixed aperture stop (3) is positioned ahead of these areas and assigned to them. The microcode line can be displaced in relation to the fixed aperture stop (3) in (n-1) discrete steps in such a way that in each case a complete number n of partial areas is detected through the opening (Sp).

Abstract: The invention relates to a controllable micro-slit line for spectrometers. A first membrane (1) is provided with n identical slits (11), whereby n > 2 and is associated with a second membrane (2) which is placed at a preferably short distance therefrom and which is divided in the direction of displacement into n areas (b1-n) each with n sub-areas (bx1-xn) where x = 1àn. At least one sub-area (bx1-xn) of each area (b1-n) is configured as a non-transparent segment and the remaining sub-areas are embodied in the form of recesses in the membrane (2). The total number of areas (b1-n) is the same as the number of slits (11) in the first membrane (1). The first and second membrane (1; 2) can be moved in such a way using means of displacement so that each slit (1) in the first membrane (1) is optically sealed at least once by one segment of the second membrane (2).

Abstract: The invention relates to an arrangement for surface plasmon resonance spectroscopy. The objective of the invention is to create an arrangement in a miniaturized form, whereby said arrangement is embodied as a portable unit that is economical to produce and can be used to carry out simultaneous multi-component analysis, especially with respect to interaction between bio-molecules. To achieve this aim, the inventive device consists of an optical prism (1) with a sample cell (2) associated therewith and at least two sample detection areas (21; 22) that are provided with a thin metal coating that is selected for the implementation of the SPR method and which contains, at least partially, surface-immobilized areas. Light emanating from a broadband light source (L) is conducted via an optic fiber (31) and collimated by a collimator (41) with an aperture that is adapted to the base surface of the prism, making its way to an entrance surface (11) of the optical prism (1) and a multi adpatable diaphragm (5) is provided between the collimator (41) and the entrance surface (11). Said diaphragm clears a defined optical path to the base surface (13) of the prism in a chronologically successive manner and the respective switching states thereof can be fed to an evaluation and control unit (6) via a data and control line (61) wherein current diaphragm switching states can be allocated to spectra corresponding to said switching states, whereby the spectra are obtained by detecting the light that leaves the exit surface (12) of the prism by means of another collimator (42) that is adapted to the base surface (13) of the prism in the aperture and whose exit is connected to another optic fiber (32) and the exit thereof forms the entrance to a polychromator (7) wherein the spectrally decomposed light is supplied to a CCD or diode array (71), whereby the exit thereof is connected to the evaluation and control unit (6) by means of a data line (62).

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: Standardization is achieved for FTIR spectrometric instruments that effect an intrinsic distortion in spectral information, the distortion being associated with an aperture size. An idealized function of spectral line shape is specified. With a small calibration aperture, spectral data is obtained for a basic sample having known "true" spectral data, and standard spectral data also is obtained for a standard sample. With a larger, normal sized aperture, standard spectral data is obtained again for the calibration sample. A transformation factor, that is a function of this data and the standardized function, is applied to spectral data for test samples to effect standardized information. In another embodiment, the standard sample has known true spectral data, and the basic sample is omitted. In either case, the transformation factor is applied to the sample data in logarithm form, the antilogarithm of the result effects the standardized information.
