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: 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.

Abstract: Provided is a spectrofluorophotometer acquiring both a spectrum and a sample image in measurement of fluorescence of a liquid sample.
A spectrofluorophotometer includes a light source, an excitation-side spectroscope that performs spectral dispersion of light of the light source and generates excitation light, a fluorescence-side spectroscope that performs spectral dispersion of fluorescence emitted from a sample irradiated with excitation light into monochromatic light, a sample container installation portion for holding a sample container which receives a liquid sample and is formed of a transparent material, a detector that detects fluorescence emitted from the liquid sample, and an image capturing device that captures a sample image of a sample emitting fluorescence. The sample container installation portion includes a port for allowing excitation light to pass therethrough, a port for allowing fluorescence emitted from a sample to pass therethrough, and a port for allowing the image capturing device to observe a sample.
