The invention relates to a system (10) for measuring, particularly in transdermal fashion, the presence and/or the concentration of an analysis substance dissolved in a bodily fluid, comprising a light source (12) for emitting excitation light (14), comprising an optical device (16), which defines an excitation beam path (22) from the light source to a measuring region (18) of a sample (20) for the excitation light and which defines a detection beam path (28) from the measuring region of the sample to a detection device (26) for scattered light (24) from the measuring region of the sample, and comprising a detection device (26) for detecting the scattered light. The detection device comprises a light-sensitive sensor (40) and at least one filter element (48) disposed in the detection beam path, wherein the at least one filter element is embodied to suppress a transmission of light with wavelengths outside of a (respective) analysis wavelength range around a (respective) Raman resonance, to be analysed, of the analysis substance. |
