<p>An imaging device for measuring the number of minute objects that are excited by irradiation light in a plurality of different wavelength areas and produce feeble light having wavelengths respectively different from the wavelength areas of the irradiation light. An imaging device for imaging minute objects to be picked up that emit light, according to irradiation light in at least two wavelength areas, at wavelengths different from the wavelengths of the irradiation light, for conversion into electric signals, the device comprising a stage mounting thereon an object to be picked up including minute objects, a light source means for irradiating the object-mounting surface of the stage, a light switching means for switching irradiation light beamed from the light source means to rays of light in a plurality of different wavelength areas, a lens means for condensing light from the object irradiated with rays of light in the different wavelength areas, a photoelectric conversion means for converting a two-dimensional image light condensed by the lens means into an electric signal, and at least two filter means switched according to the switching of rays of light by the light switching means, the filter means being disposed between the lens means and the irradiation light emitting position of the light source means on the light path.</p> |
