Abstract (en)
[origin: WO2019204840A1] The invention relates to an optical measuring unit (500) for obtaining measurement signals of fluid media which are received in cuvettes (201) that lie against each other in a row, comprising a light-providing unit (540) for dispensing an inlet radiation into the cuvettes (201) and comprising a detection unit (550) for detecting a measurement radiation exiting the cuvettes (201) and converting the measurement radiation into an electric measurement signal. According to the invention, the light-providing unit (540) has multiple LED light sources (541) with an emission that varies spectrally in the UV/VIS/NIR wavelength range, wherein the cuvettes (201) lying against each other in a row form a stationary cuvette array (200), and the detection unit (550) of the optical measuring unit (500) is designed such that each cuvette (201) of the cuvette array (200) is paired with at least one photodiode (551) in a fixed manner.
