PURPOSE:To execute the temperature adjustment of the large aperture reflecting mirror with a simple construction by providing the temperature adjusting device in the internal part and fitting the dividing mirror divided into plural pieces on the surface of the dish-shaped panel having the recessed curved surface approximate to the ideal curved surface. CONSTITUTION:A dish-shaped panel 9 is provided which has the temperature adjusting device composed of a heat transfer media passage 10 communicated to a media inlet 5 and a media outlet 6 and has the recessed curved surface approximate to the ideal curved surface. Plurally divided and formed dividing mirrors 8 are arranged and fixed on the surface of a dish-shaped panel 9, and a mirror surface 1 is constituted. Thus, the heat transfer media are sent from the media inlet 5 into the heat media passage 10, collected from the media outlet 6, and thereby, the dish-shaped panel 9 can be adjusted to the optional temperature. Consequently, respective dividing mirrors 8 can be indirectly adjusted to the optional temperature by the convection heating and the radiation heating from the dish-shaped panel 9. |
