Multi-wave spectroscopic photometer

Abstract

Abstract PURPOSE:To enlarge the wavelength range to be measured and to reduce the cost by operating a plurality of self-scanning type detectors in a charge stored mode and by integrally processing the outputs of the detectors. CONSTITUTION:The light emanating from its source 4 passes through an incident slit 5 and is diffrated by detectors 6a and 6b the resultant lights enter self-scanning type detectors 7 and 8. More specifically, the detector 7 receives a shorter wave light of lambda1 to lambdax, whereas the detector 8 receives a longer wave light of lambdax+1 to lambdan such that the storate time Ts is obtained to have proper quantity of incident light and that the scanning operations are carried out in the order lambda1 lambdax, lambdax+1 lambdan by the scanning circuits of the detectors 7 and 8. The output signals of the detectors 7 and 8 are integrated as if the wavelength ranges of lambda1 lambdan are continuously scanned. Thus, it is possible to enlarge the wavelength range and to reduce the cost.
