ABSTRACT:
An entrance slit and exit slit of a monochromator is shaped so that the width of the slits becomes smaller from the center towards the ends of their height, where the width is a dimension in the direction of the separation of the light in the monochromator. An example of such shape is rhombic. When the total amount of light emitted from the monochromator and the resolution of the monochromator are set to be the same, the efficiency of light in measuring small samples is increased and the ratio of stray light in the light emitted from the monochromator becomes smaller.
