Abstract

PURPOSE:To remove a light standing wave noise by arranging a light absorbing plate or light absorbing film provided with a light absorbing film in an area except a light transmission area on the surface of a field mirror. CONSTITUTION:First and second primary mirrors 21 and 23 composed of spherical mirrors and the field mirror 22 composed of a spherical mirror are arranged opposite each other. Light guide to the mirror 21 is reflected in the order of the mirrors 22, 23, 22, and 21. At this time, a light absorbing means 31 which has light transmission areas l0, l1, l2... where reflected light beams from the mirrors 21 and 23 pass is provided in front of the mirror 22. Then the phenomenon that spots of laser light beams which are made incident on the mirror 22 and reflected by its surface overlap each other is removed. Consequently, reflected light beams are prevented from interfering with each other and the light standing wave noise is removed.
