SPECTROSCOPIC DEVICE |
摘要 |
A spectroscopic device (10) comprising an optical fiber bundle (12) having its output end (12a) arranged in a vertical direction, a slit (16) provided so as to face the output end (12a) of the optical fiber bundle (12), a spectroscopic element arranging means (20) capable of arranging, on the optical path of light output from the output end (12a) of the bundle (12) and passed through the slit (16), a first diffraction grating (23) provided with a groove extending along a vertical direction at a specified line dispersion horizontally and a second diffraction grating (24) provided with a groove extending along a vertical direction at a line dispersion larger than that for the first diffraction grating (23) horizontally so as to enable switching between the diffraction gratings, and a photomultiplier (30) comprising a plurality of horizontally−arranged rows of anodes (53) extending along a vertical direction.
