Patent ID: 11371936

Abstract:
A multiwavelength-light-radiating apparatus (1) includes: a light source (11) that radiates continuous light (Lc); a diffracting part (12) that diffracts the continuous light (Lc) into numerous monochromatic lights (Lm), whose wavelengths differ from one another, and emits the numerous monochromatic lights (Lm); numerous optical waveguides (2) that respectively transmit the numerous monochromatic lights (Lm) emitted from the diffracting part (12) from incident ends (21) to output ends (22) where the numerous monochromatic lights (Lm) are respectively emitted; and a sample-placement part (3) that holds numerous samples such that the output ends (22) of the numerous optical waveguides (2) respectively oppose the samples. The numerous monochromatic irradiation lights, whose wavelengths differ from one another, are arranged to be radiated simultaneously onto the numerous samples, one light per sample.
