Patent ID: 8264680

Claim:
A combination, comprising: a biochip on which a plurality of samples are provided as spots or an array in a two dimensional manner on a surface of said biochip, and a biochip reader comprising: a microscopic optical system selected from the group consisting of a scanning confocal optical system, a non-scanning confocal optical system, and a 2-photon excitation optical system; a light source which irradiates excitation light simultaneously on a plurality of samples provided as spots or an array in a two dimensional manner on a surface of a biochip, and which causes said plurality of samples to emit fluorescent light different in wavelength from said excitation light; a single optical detector which detects said fluorescent light emitted by said plurality of samples as spectroscopic information; and a grating, a prism spectrometer, dichroic mirrors, or a Fourier spectrometer which refracts said fluorescent light emitted by said samples and develops said fluorescent light as said spectroscopic information at different locations on said single optical detector according to wavelength, said spectroscopic information being developed between images of adjacent samples among said plurality of samples, wherein said spectroscopic information is detected by said single optical detector in a two dimensional manner.
