Spectrometry apparatus and spectrometry method

Abstract

A spectrometry apparatus () according to the present embodiment includes a light source () that produces illumination light, a spectrophotometer () that disperses signal light rays from a sample illuminated with the illumination light and detects the signal light rays by a photodetector (), a fiber unit () having a plurality of fibers, the plurality of fibers () being adjacently arranged at an entrance end surface () of the fiber unit (), and the plurality of fibers () being arranged in a multi-line shape at intervals at an exit end surface, and a processing unit that, by referring to a positional relationship among the plurality of fibers () at the entrance end surface and an exit end surface of the fiber unit (), generates a spectroscopic image of the sample S from a result of detection by the photodetector.
