LASER COMPONENTS now also manufactures lead selenide (PbSe) detectors with four channels. The quad version is an attractive alternative for gas measurement applications when a higher D* value or higher speed is desired.
Four selected PbSe chips are arranged in quadrants and equipped with their own filter to detect different wavelengths. The readout of all channels is carried out simultaneously.
With these new detectors, you can measure and analyze gas mixtures simultaneously. In addition, you save space and cost: instead of four single detectors or a filter wheel, you can simply use a TO-8 or TO-39 housing. For an improved signal in the long- wave range, cooled versions are also available.
