Patent ID: 7403286

Claim:
A spectroscopic analyzing apparatus, comprising: a spectroscope for separating incident light into one or more wavelength components; a plurality of detectors each taking charge of the associated one of a plurality of wavelength ranges that are divided from a detection wavelength range, said detectors being optically connected to said spectroscope and arranged such that optical path lengths from said spectroscope to respective photodetecting faces of said detectors are made coincident with each other, each of said detectors having a sensitive region narrower than the spectrum band of light reaching from said optically connected spectroscope to said detectors; and direction changers provided in connection with one or more detectors among said plurality of detectors, said direction changers being arranged on optical paths of the wavelength components that propagate from said spectroscope to said associated detectors, and functioning to change the propagation directions of the wavelength components, wherein said plurality of detectors are arranged so as to prevent the desired wavelength components separated by said spectroscope from reaching insensitive regions of said plurality of detectors, by using the function of said direction changers.
