Abstract: To increase the sensitivity of detector arrangements, it is known that light deflection elements in the form of a line arrays having spherical elements may be used to focus incident light onto light-sensitive regions of the detector. Manufacturing such line arrays is complex and cost intensive, especially in small lot numbers. The increased sensitivity of the detector array can be achieved easily and inexpensively by using a novel light deflection element. The detector arrangement therefore has a light deflection element having light entrance surfaces, deflecting incident light by refraction onto light-sensitive regions of the detector. Light entrance surfaces of the light deflection element are inclined with respect to one another and are designed as planar surfaces. The detector arrangement is suitable in particular for detection of light emanating from a specimen in a microscope, preferably in a laser-scanning microscope.

Abstract: A Raman analyzer for analyzing light emitted from a Raman cell is provided that has a beam splitter configured to split the light emitted from the Raman cell into a first beam and a second beam. An atomic vapor filter can be used to filter a Raman scattered line from the first beam and a chopper system can periodically interrupt the first and second beams that are directed towards a photo detector, which can convert light from the first and second beams into an electrical signal. The signal output from the photo detector can optionally be amplified, digitized, Fourier filtered, and/or subjected to Fourier analysis.

Abstract: A method for monitoring of siloxane compounds in a biogas includes the step of generating a first absorption spectrum based on a ratio of a first spectral measurement and a second spectral measurement. The first spectral measurement is from a non-absorptive gas having substantially no infrared absorptions in a specified wavelength range of interest and the second spectral measurement is from a sample gas comprising the biogas. The method also includes the step of calculating a concentration of at least one siloxane compound in the biogas using a second absorption spectrum based on, at least, a first individual absorption spectrum for a known concentration of the at least one siloxane compound.

Abstract: Spectrometric apparatus that include an array of detector elements and exhibits a number of capabilities is disclosed. The elements can be responsive to incident radiation to produce an output signal that includes information from the incident radiation. A spectrally selective element can be located in an optical path between the radiation source and the array, with an analysis module responsive to the output signal operative to analyze spatial distribution of spectral information received by the array. The apparatus can also correct for differences in intensity and spectral variability for spectral image signals and/or compare the spectral image signals with a pattern in spatial-spectral coordinate space. Detector elements can be responsive to scattering, and spatial information in their output can be analyzed.

Abstract: The invention relates to a sensor device (100) in which the spatial distribution of an input light (L1) emission from a light emitting area (121, 122) of a light source (120) can selectively be changed. The input light is propagated through an optical system (110) to produce some output light (L2). Changes of the input light are taken into account when the detected output light (L2) is evaluated. Thus it is for example possible to detect and/or eliminate optical disturbances occurring in the optical path outside an object region (3). The light source (120) may particularly comprise a plurality of a light emitting segments (121, 122) that can selectively be switched on or off.
