SPECTROSCOPIC DEVICE, AND METHOD FOR DRIVING THE DEVICE

摘要

Provided is a spectroscopic device of a new constitution, which is suited for detecting precisely a fluorescent light emitted from an inspection object in a fluorometric analysis, such as a DNA.  The spectroscopic device (10) comprises a spectroscopic sensor body (21) for outputting the quantity of charge corresponding to the intensity of such a light of a spectroscopy object as corresponds to the intensity of a light having a wavelength component of a wavelength specified with the value of a gate electrode or larger, and a floating diffusion unit (51) for outputting a voltage according to the quantity of charge outputted from the spectroscopic sensor body (21).  The floating diffusion unit (51) includes a plurality of serially connected charge wells (53 and 55), for which output voltages are individually detected.
