摘要： The invention relates to a device and to a method for measuring photoluminescence in a fluid present in a measurement vessel. According to the invention, the fluid in the measurement vessel simultaneously receives at least two excitation beams coming from two optical systems. The optical systems are positioned so that their axes form between them a non-zero obtuse angle other than 180° around the measurement vessel. A measurement of light emission is deduced according to the invention from coupling data obtained from emission beams picked up simultaneously by the pickup elements. The optical systems are also positioned in such a manner that there exists at least one partial overlap beam between the excitation beam from the source of a first optical system and the emission beam picked up by the pickup element of a second optical system. The device is also provided with at least one extinction pickup element in the vicinity of at least one of the sources for picking up light at the excitation wavelength in the partial overlap beam, a measurement of absorbance and/or diffraction being deduced from data obtained from the light picked up by the extinction pickup element.
