Abstract: A spectroscopic measurement apparatus includes a light source, an integrator, a first spectroscopic detector, a second 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, and a sample attachment portion for attaching the measurement object. The first spectroscopic detector receives the light output from the integrator, disperses the light of a first wavelength region, and acquires first spectrum data. The second spectroscopic detector receives the light output from the integrator, disperses the light of a second wavelength region, and acquires second spectrum data. The first wavelength region and the second wavelength region include a wavelength region partially overlapping each other.

Abstract: A spectroscopic measurement apparatus includes an optical system, a photodetector, and an analysis unit. The optical system guides measurement target light from an object to a light receiving surface of the photodetector, and forms a spectral image of the measurement target light on the light receiving surface of the photodetector. The photodetector includes the light receiving surface on which a plurality of pixels are arranged respectively on a plurality of rows. The photodetector receives the spectral image for a first exposure time by a plurality of pixels in a first region on the light receiving surface, and outputs first spectrum data. The photodetector receives the spectral image for a second exposure time by a plurality of pixels in a second region on the light receiving surface, and outputs second spectrum data. The second exposure time is longer than the first exposure time.

Abstract: A spectrometry device includes a light source, an integrator configured to have an internal space in which a long afterglow emission material is disposed and output detection light from the internal space, a spectroscopic detector, an analysis unit configured to analyze a photoluminescence quantum yield of the long afterglow emission material, and a control unit configured to control switching between presence and absence of input of excitation light to the internal space and an exposure time in the spectroscopic detector. The control unit controls the light source so that the input of the excitation light to the internal space is maintained in a first period and the input of the excitation light to the internal space is stopped in a second period, and controls the spectroscopic detector so that an exposure time in the second period becomes longer than an exposure time in the first period.

Abstract: An optical measurement device inputs excitation light to an integrating sphere in which a sample is disposed, irradiates the sample with the excitation light having a predetermined beam cross-section, detects measurement light output from the integrating sphere by a photodetector, and acquires intensity data of the sample. The optical measurement device includes a storage unit in which correction data is stored and an optical characteristic calculation unit for calculating optical characteristics of the sample based on the intensity data of the sample and the correction data. The correction data is calculated based on first corrective intensity data and second corrective intensity data. The predetermined beam cross-section is covered with the first light absorbing member and covers the second light absorbing member.
