The invention relates to an ATR spectrometer for analysing the chemical composition of a sample, wherein the ATR spectrometer () comprises an ATR crystal (), at least one infrared light source () being arranged on the entry surface (), a line array () of infrared light detectors, at least one single infrared light detector (), wherein the at least one infrared light source () is adapted to emit infrared light that enters the ATR crystal and is guided to the infrared light detectors under total internal reflection and under interaction with the sample being arranged immediately adjacent to the ATR crystal, a wavelength dispersive element () being arranged in the path of the infrared light so&#x2014;that the line array is adapted to measure a spectrum of the infrared light, and a wavelength filter () being arranged in the path of the infrared light to the single infrared light detector, wherein at least one of the infrared light detectors is chosen to be a chosen infrared light detector for a signal correction, and the ATR spectrometer is adapted to use the electrical signal of the chosen infrared light detectors to correct the electrical signals of all the other infrared light detectors.

Pyroelectric detector

A method for producing an infrared light detector () has the steps of: providing a plurality of connection pins (), which are kept parallel to one another and arranged with one of the longitudinal ends () thereof in a horizontal plane, and a printed circuit board () with a planar underside (), in which a recess () of the same form in each case is provided for each of the connection pins (); filling the recesses () with a solder paste, so that in each of the recesses () there is a solder paste body () with the same amount of solder paste; positioning the printed circuit board () over the connection pins (), so that each of the connection pins () extends with its longitudinal end () in the recess () assigned to it and dips in the solder paste body () located in the respective recess (); liquefying the solder paste bodies (), so that electrically conducting connections are formed between the connection pins () and the solder paste bodies () and, on account of the surface tension in the solder paste bodies () and the dead weight of the printed circuit board (), the underside () of the printed circuit board () is aligned parallel to the horizontal plane; solidifying the solder paste bodies (), so that mechanically secure connections are formed by the solder paste bodies () between the printed circuit board () and the connection pins () and the alignment of the underside () of the printed circuit board () parallel to the horizontal plane is fixed.
