Abstract: A spectrometry device includes: an integrating sphere which includes an inner wall surface and an attachment hole; an adapter which includes a guide hole guiding the measurement target light and is disposed in the integrating sphere; a plate which includes a first surface covering the guide hole from the outside of the integrating sphere and allowing a sample to be mounted thereon and a second surface and through which the measurement target light is transmitted; a holder which includes a concave portion mounting the plate thereon and is attached to the attachment hole; and a spectral detector configured to detect the measurement target light. The concave portion includes a bottom surface facing the second surface and a side surface surrounding the periphery of the plate. The bottom surface and the side surface are coated with a reflective material reflecting the measurement target light.

Abstract: An inspection apparatus includes a light source unit, cameras, a keyboard, and a controller that determines a wavelength of the excitation light, based on the information on the emission color received by the keyboard, and that controls the light source unit so that the light source unit generates excitation light with the determined wavelength. The controller determines a wavelength longer than an absorption edge wavelength of the substrate of the sample and shorter than a peak wavelength of an emission spectrum of the light-emitting element, the peak wavelength being specified from the information on the emission color, to be the wavelength of the excitation light.

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.
