Claim Text:
1. An apparatus for analysing or measuring fluorescence, luminescence, phosphorescence, Raman scattering or absorption in a small amount of a liquid sample using light which can be guided through the sample and then detected or analysed according to said measurement methods, the apparatus comprising: a sample holder disposed at the top in a working position with a receiving point for application or dripping of the sample; a light inlet oriented horizontally in the working position below the sample holder for excitation light that forms a beam; a first light deflector located downstream of the light inlet in a beam path to deflect the beam upward to a position next to the receiving point; a second light deflector which deflects the light beam coming from below horizontally into the sample to be analysed to excite fluorescence; and an alternative second light deflector to measure transmission, the alternative second light deflector able to deflect the excitation light by multiple reflections downward into the receiving point and vertically through the sample.
