Abstract
The invention relates to a device (1) for photometrically or spectrometrically examining a liquid sample (2), comprising a cuvette (3, 3′), which can be arranged in the beam path between a radiation source (4) and a radiation detector (5) and which accommodates the liquid sample (2) to be examined, a radiolucent inlet section (6) for coupling in radiation (20) produced by means of the radiation source (4), which radiation interacts with a sample volume (8), and a radiolucent outlet section (7) for coupling out radiation (20″) intended to be detected in the radiation detector (5), wherein the inlet section (6) has an inlet surface (11) convexly curved in such a way and/or the outlet section (7) has an outlet surface (12, 12′) spherically convexly curved in such a way that the incident radiation (20, 20′) is focused in the manner of a converging lens.
