(Effects of the Invention) - As explained above, this invention provides a mirror body with a convex cross-section and a mirror surface on the surface of the protrusion, and uses one point on the outer periphery of the mirror body as a fulcrum, and a plurality of points. Because it is attached to the base plate as an adjustment part, that is, because the mirror body and mirror holder are integrally formed from one member,
There is no distortion on the mirror reflection surface, and the light mode is transmitted uniformly and stably. Furthermore, if the light reflecting surface is damaged, it can easily be repolished, and there is no need to replace it with a new mirror, making it inexpensive. Furthermore, since the mirror itself can be directly cooled, no thermal distortion occurs on the mirror.
