Abstract: The invention is directed to an arrangement for detecting coatings which are arranged on surfaces of structural component parts or objects and for determining the chemical characteristics and surface properties of these coatings. It comprises a light source for illuminating the coating to be analyzed on the surface of the structural component part and means for imaging the light source on an entrance slit over the surface of the coating to be analyzed. The entrance slit is imaged in a wavelength-dependent manner on a two-dimensional detector unit by a grating. An evaluating unit which is electrically connected to the detector unit serves to evaluate and process the signals supplied by the exposed detector elements of the detector unit.

Abstract: The present invention provides an optical analysis system for determining an amplitude of a principal component of an optical signal. The principle component is indicative of the concentration of a particular compound of various compounds of a substance that is subject to spectroscopic analysis. The optical signal is subject to a wavelength selective weighting. Spectral weighting is preferably performed by means of spatial light manipulation means in combination with a dispersive optical element. The inventive calibration mechanism and method effectively allows for an accurate positioning of the spatial light manipulation means. Calibration is based on a calibration segment on the spatial light manipulation means in combination with a reference light source and a detector.

Abstract: A two-channel spectrometer has a shared objective and a pair of slits at a common image plane. Each of the slits receives a portion of the output beam of the shared objective and is optimized for transmitting different wavelengths. A shared double-pass reflective triplet receives the output beams of the slits. The output of the reflective triplet is incident upon a beamsplitter, which sends a collimated first reflective triplet output of a first wavelength to a first dispersive element, and a collimated second reflective triplet output of a second wavelength to a second dispersive element. The outputs of the dispersive elements are directed back to the beamsplitter and the reflective triplet to imaging detectors located at two different locations of the common image plane.

Abstract: To achieve a given spectral resolution with reduced detector size and commercially available pixel pitches, the Raman spectrum is shifted across the detector array such as by one of the following methods: 1) tuning the excitation wavelength; 2) rotating the grating; 3) displacing the effective input slit (fiber) and acquiring the spectrum under stepped displacement conditions; and 4) displacement of a lens relative to input fiber to displace effective input slit relative to the detector. A composite spectrum is formed and deconvolution of the entrance aperture image and/or pixel masking is then used.

Abstract: An optical slit comprises two blades 40,42 which define a slit between them, each blade being independently movable. This enables both the slit position and the slit width to be adjusted. The slit may be aligned with the center of a light beam by aiming the light beam at a detector, traversing at least one edge of the slit across the beam path, measuring the intensity of transmitted light at the detector for each position of the slit, and feeding back a signal which adjusts the slit position for maximum light throughput. The width on the optical slit may be selected by placing the slit in the path of the light beam and measuring the light transmitted at the detector, calculating the percentage of light transmitted for that slit width and feeding back a signal which adjusts slit width to obtain the desired amount of light throughput.
