ABSTRACT:
A fluorescence detection apparatus is provided which has a partial reflection mirror 8 for transmitting a part of fluorescence light emitted from a fluorescent substance by projecting excitation light and reflecting the rest of the fluorescence light, and a pair of a first and a second photodiode 2,3 for measuring the light transmitted through or reflected by partial reflection mirror 8 respectively at a selected wavelength, and the pair of the first and the second diodes are arranged to be optically equivalent relative to the partial reflection mirror 8. This fluorescence detection apparatus is affected less by positional deviation of the measurement cell relative to the optical measurement system.
