An optical device is mounted to an electronic circuit having a main face with at least one light source. The optical device is made from a block which includes, for each light source, a corresponding opening that passes through the block. The opening includes a cylindrical part with a threading on an inside surface.

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.
