SOLUTION: A light source 11 emits at least light with a first wavelength. A diffraction optical element 12 is constituted so as not only to reflect the exciting light with the first wavelength emitted from the light source 11 to guide the same to a sample S but also to permit fluorescence with a second wavelength shifted from the first wavelength by the sample S to transmit to separate the exciting light with the first wavelength and the fluorescence with the second wavelength. A fluorescence detector 14 detects the fluorescence with the second wavelength separated by the diffraction optical element 12. COPYRIGHT: (C)2005,JPO&NCIPI
