MULTI-SPECTRAL LIGHT SOURCE ILLUMINATION AND FLUORESCENCE DETECTION

摘要

A device to illuminate a object, to excite its fluorescence light emission, and detect the emitted fluorescence spectrum, comprising: at least one illumination system (13), adapted to receive light from a light source (11), to select at least one wavelength bands of light spectrum of the source (11), to illuminate a object (15) with light filtered in that way (14); and a detection system (17), adapted to detect fluorescence light (16) emitted by the object (15), to select at least one wavelength bands of fluorescence, light spectrum (16), to record the spectrum of the filtered light; characterized in that said illumination system (13) comprises: at least one first dispersive element (41), at least one focusing optics (43), at least one spatial fitter of excitation (44), at least one collimating optics (45) and at least one second dispersive element (47), wherein said detection system (17) comprises: at least one dispersive element (81), at least one focusing optics (83), at least one spatial filter of detection (84), at least one imaging optics (85) and at least one light detector (87).
