摘要： An excitation beam from a laser is passed through a bandpass filter, and applied to a sample by a collimator lens. An optical adjusting part comprising a camera lens and a converging lens is provided for receiving scattered light from the sample, so that the camera lens receives the scattered light and converts the same to a parallel beam. The converging lens has chromatic aberration, and receives and converges the parallel beam from the camera lens. An inlet slit of a spectroscope is provided as an inlet port on a converging position by the converging lens. This inlet slit is a circular hole having a diameter of about 200 .mu.m. The inlet slit is arranged on a position for converging anti-Stokes-Raman scattered light through the chromatic aberration of the converging lens.

摘要： Excitation light from a light source is divided into a sample beam and a correction beam by a half mirror, so that the sample beam is converged on a sample in a sample part by convergent lenses. Condenser lenses are provided in order to converge scattered light from the sample on an inlet slit of a spectroscope, and a holographic notch filter which is set to include the wavelength of the excitation light in its notch region is arranged in order to remove the same wavelength component as the excitation light from the scattered light for selecting target light. The target light and the correction beam are guided onto the same optical axis by a half mirror, to be incident upon a polychrometer through the inlet slit and simultaneously detected. The detected value of the target light is corrected by a simultaneously detected intensity of the correction beam.
