摘要： The invention provides a device for measuring characteristic quantities of an at least partially transparent sample, comprising: an illumination component including a light source (1) which emits light in a predetermined wavelength range and which is arranged such within this illumination component that the light substantially propagates along a predetermined optical axis, a sample reception space provided between this illumination component and a measuring component and arranged such with respect to this optical axis that the light which emerges from the light source first passes a sample located within that sample reception space and then enters this measuring means, a measuring component including a substantially closed measuring space having an opening through which this optical axis extends and through which the light enters after having passed the sample, and which also includes a photodetector component (2) being sensitive at least within this predetermined wavelength range, including at least two detectors, namely a first detector (4) arranged in the optical axis (3) of the illumination component and a second detector (5) arranged in a predetermined radial distance from this optical axis.
