Abstract

PURPOSE:To employ the light by providing the condensing mirror for focusing the light flux on the effective surface of the scattered element and at the same time condensing the light emitted from the light source mirror to the incident slit correctly. CONSTITUTION:The troid mirror 7 having a large axis trip angle is placed in such a manner that the image of the maximum effective reflecting surface of the light source mirror 2 is formed in the effective area of the scattered element 4 in front of the incident slit 3. Thus, is accordance with the operation of the troid mirror, the displacement in focussing in the horizontal and the longitudinal directions can be neglected, the optical design in the spectroscope can be easily done. Further, since the axis trip angle is large, the mirror 7 can be readily placed near to the incident slit and the light flux be enlarged and the light be effectively focused.
