PURPOSE:To simply and accurately perform the regulation of irradiation intensity, by arranging a reflex mirror formed by connecting a plurality of heat ray pervious reflection plates in an inner enclosure having an exhaust port. CONSTITUTION:A cylindrical inner enclosure 3 having an exhaust port 2 is received in an outer enclosure 1. In the inner enclosure 3, a reflex mirror 4 formed into a trough shape as the whole by connecting a plurality of thermic ray pervious reflection plate 4a-4e each curved in a circular arc shape so as to leave small gaps therebetween is arranged and a tubular ultraviolet ray source 5 such as a high pressure mercury lamp.a metal halide lamp is mounted to the interior of the reflex mirror 4 along the longitudinal direction thereof. An exhaust apparatus 6 is connected to the exhaust port 2 of the inner enclosure 3. By this structure, ultraviolet ray reflectivity can be changed and uniform irradiation can be performed as a whole. |
