ABSTRACT:
A cooled reflective mirror apparatus is provided, in which a reflective mirror body is so constructed as to make the cooling fluid spread in a plane covering the outer wall surface of the reflective mirror body to improve the cooling effect and in which the thickness of the reflective mirror body is made large enough to prevent excess heat from the inner side of the body from reaching the outer wall surface thereby minimizing the temperature rise in the cooling liquid to permit long hours of cooling. The curved inner surface portion is plated to form a reflection mirror surface. The cooling tank is placed in contact with the outer side of the reflective mirror body through the matching flat surface portions of the mirror body and the cooling tank. The cooling tank is fitted with cooling liquid supply and discharge pipes so that the cooling liquid supplied temporarily stays in and circulates through the tank to absorb heat from the outer surface of the reflective mirror body.
