Abstract: PROBLEM TO BE SOLVED: To prevent a stray light resulting from a light passing through an acousto-optical element and improve detection sensitivity by providing a reflecting plate for reflecting the passing light so that the passing light through the acousto-optical element does not reach a detecting face. SOLUTION: A light from an observation object image 20 enters an acousto- optical element (AOTF) 1 via a collimator lens 11. The light entering the AOTF 1 is separated to two diffraction lights 21a, 21b of predetermined wavelengths and a passing light 22 having a wavelength other than the predetermined wavelengths. The diffraction lights 21a, 21b form the observation object image on detecting faces of photodetectors 3a, 3b via imaging lenses 12a, 12b. Meanwhile, the passing light 22 is reflected by a reflecting plate 2 along a predetermined optical path so as not to reach the detecting faces of the photodetectors 3a, 3b. In this manner, the unnecessary passing light 22 is prevented by the reflecting plate 2 from reaching the detecting faces of the photodetectors 3a, 3b, so that a spectral spectrum can be measured with good sensitivity.
