Abstract

PURPOSE:To reduce the size of a spectroscope and stray light by separating the second light flux, which composed mostly of the lights of wavelengthes other than a preset level, from a first light flux, which is composed mostly of a plurality of lights of the preset wavelength and which reaches the concave diffraction grating from an incident slit, so that the second light flux may be captured.
