    Abstract: The invention relates to a multi-sensor laser system for the selective trace analysis of organic material, the multi-sensor system having at least one laser ion mobility spectrometer, an absorption spectrometer and a fluorescent measuring device. The system is characterized in that it is equipped with a device for the simultaneous generation of a common laser beam with different wavelengths and pulses for the simultaneous operation of the laser ion mobility spectrometer, the absorption spectrometer and the fluorescent measuring device. This avoids the disadvantages of the known solutions in prior art and provides an improved solution for the highly sensitive and highly selective trace analysis of organic material, in particular hazardous substances such as explosives and warfare agents in the air.

    Abstract: A gas detector (10) that is arranged to sense the concentration levels of target gases oxygen, methane, carbon monox-ide, and hydrogen sulphide, within a gas sample from an environment surrounding the detector. The gas detector (10) comprises laser sources (12a-12d) that are arranged to transmit radiation through the gas sample at four target wavelengths that correspond approximately to the optimum absorption wavelengths of each of the target gases and an optical detector (16) that is arranged to sense the intensity of the radiation transmitted through the gas sample at each of the target wavelengths. A control system (22) generates representative concentration level information for the target gases based on the level of absorption of the radiation transmitted.

    Abstract: A flat spectrum illumination source for use in optical metrology systems includes a first light source generating a visible light beam and a second light source generating an ultraviolet light beam. The illumination source also includes an auxiliary light source generating a light beam at wavelengths between the visible light beam and the ultraviolet light beam. The three light beams are combined to provide a broadband probe beam that has substantially even illumination levels across a broad range of wavelengths. Alternately, the illumination source may be fabricated as an array of light emitting diodes selected to cover a range of separate wavelengths. The outputs of the LED array are combined to produce the broadband probe beam.

    Abstract: Spectrophotometric analysis device having a feeder circuit of a test stand. The analysis device has two distinct spectrophotometers facing the same test stand, especially in order to be able to cover spectra with wavelengths that are separate and included in the wavelengths on either side of the visible range. A first spectrophotometer covers the spectrum of the near and mean infrared ranges while a second spectrophotometer covers the spectrum of the ultraviolet and visible ranges. This analysis device provides especially for the spectrophotometric determination of the different constituents contained in fluids to be analysed, such as wine, fruit juice or blood.
