Abstract
PURPOSE:To facilitate the adjustment of the optical axis on photodetectors and to improve the accuracy of measurement by condensing the reference luminous flux and sample luminous flux taken out of a switching mirror separately to the detectors and adjusting the optical path length and optical axis direction independently. CONSTITUTION:A plane mirror M3 adjusts the optical path length and optical axis direction of the sample luminous flux S light and the reference luminous flux R light to a photomultiplier D1 to the same length and direction. Switching to the photodetector D2 is executed by advancing the switching mirror M4 onto the optical path to D1. The R light and S light reflected by M4 are intersected in a position C and are then reflected and condensed by concave mirrors M5, M6 so as to be received by D2. The positions of the two luminous fluxes on the optical path length and photodetecting face of the R light and the S light are easily adjustable by adjusting M5 and M6 without affecting the adjustment of M3. The adjustment of the optical axes and optical path difference of the two luminous fluxes on the detectors is thereby facilitated and the accuracy of measurement is improved.
