Abstract

A highly reflective light-guide system has a highly reflective light-guide surface for reflecting light that has been emitted from a sample and has entered from an entry port opposing a window material and propagating the same to an exit port opposing a light reception surface of a photodetector. An optical filter is provided in a space surrounded by the window material, the photodetector, and the highly reflective light-guide system and transmits the signal luminescence to be measured that is emitted from the sample between the window material and photodetector. The optical filter is fixed to the window material or photodetector by an adhesive, and the peripheral shape of the optical filter is smaller than the shape of the inside of a fitting part to which the optical filter is fitted and that is formed on the highly reflective light-guide system.
