The article describes the basic design and essential properties of developed multispectral detectors. The presented detector concept on the basis of lithium tantalate (LiTaO(subscript 3)), a pyroelectric material, makes the parallel measurement possible in four spectral channels in the wavelength range of typically 1 - 25 micrometers . The detector consists of an optical unit with the beam splitter and interference filters for the spatial and spectral dispersion of the incident total radiation and the responsive elements with appropriate low-noise preamplifiers. The detector is a discrete and compact component in a TO 8 transistor casing (empty set 14 mm X 10 mm) with an aperture of typically empty set 2 mm. Essential properties of a four-channel detector for the gas analysis (CO; CO(subscript 2); HC; REF) are described and the influence of the beam splitter geometry on the overlap of the measuring spots in the spectral channels is discussed. As a detector application a novel multichannel pyrometer is presented by means of which the influence of the object emissivity on the measuring accuracy has been reduced considerably.
