    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.

    Abstract: This invention relates to an apparatus for retro-reflection measurement. By using the one or more sampling devices each consists of a holed mirror and an circular aperture, and corresponding one or more measuring devices, it realize the retro-reflection measurement in one or more observation angles at one time. By flexibly selecting the size of the circular apertures and holed mirrors, it can accurately adjust the measuring annular bands and corresponding observation angles. Without any other intermediate devices, it can realize complete annular band of light measurement which ensures the measurement accuracy. At the same time, filters and monitor device can be set flexibly to realize various measurement functions. It has the advantages of speed measurement, high accuracy, small volume, wide application, comprehensive functions, and can be widely applied in laboratory, industrial production line and field measurement etc.
