Abstract
PURPOSE:To eliminate the replacement of filters by arranging them on individual image detectors adapted to simultaneously detect spectra scattered according to the wavelength, as shited perpendicular to the scattered surface. CONSTITUTION:A light coming from a slit 21 is separated into spectra lambdal...lambdan with a grating and a prism. They irradiate image detectors 3, the output of which is processed with an amplifier 4, a scanner 5, an A/D converter 7, a memory 8 and the like to obtain data. The image detector 3 is composed of a plurality of detectors 31-33 and shifted perpendicular to the spectral surface (at the right angle to AA'' in the drawing) and with both ends overlapping, cut filters 36-38 are inserted into the front of the photo detection surface of the detectors as required. This enables simultaneous measurement of multiple wavelength elminating complicated replacement of the filters thereby providing a spectrometer minimizing the mixing of stray light and light of higher order.
