Abstract

PURPOSE:To align the center of a reflecting mirror to an optical axis with good reproducibility by providing a screw adjusting the reflecting mirror contained within a cylinder, and a tapered part and a screw for fitting the outside circumference of the cylinder to a base. CONSTITUTION:A condensing leng 601 and a 1/4 wevelength plate 602 are fixed to a cat's eye holding frame 610, and underlying glass 604 having a reflecting mirror surface 603 is supported adjustably by an adjust screw 620. A holding frame 61 is fitted and fixed to a base 300 by means of the tapered surface 611 and screw part on the outside circumference of the frame 610. After the reflecting mirror surface 603 is center aligned by turning the screw 620 from the outside, the screw 620 is fixed by lock paint or the like. Thereby, the center of the mirror 603 is aligned to the optical axis with good reproducibility.
