<p>In a spectroscopic analyzer, light emitted from a light source (20) is spectroscopically divided into a series of light rays of different wavelength by means of a plural sets of interference filter (29a; 29b, 29c; 29d, 29e, 29f) for two-wavelength photometry adapted to intermittently and successively intercepting light from the light source or to be scanned by the light through a rotatable slit (130). An object (32) under test is irradiated sequentially by the series of light rays transmitted through an optical fiber bundle (33). Reflected light rays carrying informations of the object are sequentially applied to photoelectric converter (38). Electric signals thus produced are digitized and arithmetically processed for obtaining a plurality of data corresponding to the plural sets of the interference filters (29a; 29b, 29c; 29d, 29e; 29f).</p> |
