1′
) for measuring the concentration of at least one analyte in a fluid sample (2;
2′
),with a light source (3;
3′
) to generate a light beam (4;
4′
),with a photosensor (5;
5′
) to receive the light beam (4;
4′
), andwith a measurement length (6;
6′
), in which the fluid sample (2;
2′
) can be placed, in the beam path of the light beam (4;
4′
),the measurement length (6;
6′
) being provided in changeable form,characterised in thatthe light source (3;
3′
) and the photodetector (5;
5′
