Abstract: A fluorescence photometer includes a photometer unit and an optical fiber unit. The photometer unit includes a light source, an excitation-side spectroscope for separating light emitted from the light source to generate excitation light, and a fluorescence-side spectroscope for separating fluorescent light emitted from a sample irradiated with the excitation light to generate monochromatic light. The optical fiber unit guides the excitation light to the sample placed outside the photometer unit and guides the fluorescent light emitted from the sample to the photometer unit and includes an image fiber for capturing an image of the sample, an excitation-side fiber arranged around the image fiber and for guiding the excitation light to the sample, and a fluorescence-side fiber arranged around the image fiber and to guide the fluorescent light emitted from the sample to the photometer unit. The excitation-side fiber and the fluorescence-side fiber are arranged to surround the image fiber.

Abstract: A fluorescence spectrophotometer includes: a light source; an excitation side spectroscope configured to separate light from the light source to generate excitation light; an integrating sphere having an inner surface configured to scatter the excitation light that has entered the integrating sphere; a sample holder, which is provided at a position on the integrating sphere that is not directly irradiated with the excitation light that has entered the integrating sphere and that is capable of being irradiated with the excitation light that has been scattered by the inner surface, and which is capable of holding a sample to be measured; a detector configured to detect fluorescent light emitted from the sample irradiated with the excitation light that has been scattered by the inner surface; and an imaging device configured to take the sample image of the sample that emits the fluorescent light.

Abstract: To acquire both excellent spectrum and sample image reflecting actual conditions of a sample, and to increase convenience of measurement, provided is a display device for a photometric analyzer, which is configured to irradiate a sample with light to analyze the sample, the display device being configured to display a measurement result of the photometric analyzer, and including: a controller; and a display, which is configured to display an image based on measurement data processed by the controller. The measurement data at least contains a spectrum indicating an intensity of emitted light, which is emitted by the sample irradiated with the light, and a sample image of the sample, which is taken by an imaging device. The display is configured to display the spectrum and the sample image in an arrangement in the same screen.
