Abstract
A spectroscopic measurement apparatus includes a light source, an integrator, a spectroscopic detector, and an analysis unit. The integrator includes an internal space in which a measurement object is disposed, a light input portion for inputting light to the internal space, a light output portion for outputting light from the internal space, a sample attachment portion for attaching the measurement object, and a filter attachment portion for attaching a filter unit. The filter unit has a transmission spectrum in which an attenuation rate for excitation light is larger than an attenuation rate for up-conversion light, and attenuates the light output from the light output portion. The analysis unit analyzes luminous efficiency of the measurement object on the basis of the transmission spectrum data and the spectroscopic spectrum data acquired by the spectroscopic detector.
