Abstract
In order to make a Raman spectral measuring apparatus effective for measurement of a vital sample and attain miniaturization and weight reduction, a near infrared laser diode is employed as a light source, and a spectroscope for receiving Raman scattered light from the sample is formed by a polychrometer comprising a concave diffraction grating and a multichannel photodiode array. The Raman scattered light incident through an inlet slit is separated into its spectral components by the diffraction grating, and its spectra are simultaneously detected by the photodiode array over a prescribed wavelength region.
