Abstract
Embodiments create an arrangement and a method for analyzing a fluid. The arrangement (10) for analyzing a fluid comprises beam splitter and mixer optics (12) configured to spatially mix an optical signal and split the same into at least two spatial sub-beams and a flow cell (14) configured to spectrally influence at least the two spatial sub-beams (15a; 15b) by means of a probe of the fluid. The arrangement further comprises a measurement system (16) configured to measure the at least two spatially separated sub-beams (15a; 15b).
Claims20
An arrangement for analyzing a fluid, comprising:
- a flow cell configured to spectrally influence an optical signal by means of a probe of the fluid;
- beam splitter and mixer optics configured to spatially mix the optical signal and split the same into at least two spatial sub-beams,
- wherein a spatial sub-beam comprises a portion of the optical signal that passes through essentially the entire probe;
- and
- a measurement system configured to measure the at least two spatially separated sub-beams,
- wherein the beam splitter and mixer optics comprise a diffractive optical element, and
- wherein the diffractive optical element is configured to perform a beam splitting of 1 to n into n sub-beams for n measurement fields, wherein n is a non-negative integer greater than 1.
A method for analyzing a fluid, comprising:
- spatially mixing and splitting an optical signal into at least two spatial sub-beams using a diffractive optical element;
- influencing the at least two spatial sub-beams with a probe of the fluid,
- wherein a spatial sub-beam passes through essentially the entire probe;
- and
- measuring the at least two spatial sub-beams,
- wherein the diffractive optical element is configured to perform a beam splitting of 1 to n into n sub-beams for n measurement fields,
- wherein n is a non-negative integer greater than 1.
