Apparatus for irradiating ultraviolet rays

Abstract

Abstract PURPOSE:To prevent the rising in the temp. of a workpiece by infrared rays, by arranging always cooled transparent quartz glass between an ultraviolet lamp and the workpiece. CONSTITUTION:The quartz glass plate 9 arranged between an ultraviolet ray emitting light source body 1 and net belt 8 has a film comprising a special metal formed to the surface thereof and reflects infrared rays from ultraviolet rays emitted to a workpiece 14 from the ultraviolet ray emitting light source body 1 and performs the abosrptive removal thereof. A cooling mechanism 10 is assembled and fixed to said quartz glass plate 9 to cool the work 14, which rises in its temp. by infrared rays which could not be removed, by the spraying of cold. By this method, ultraviolet ray irradiating treatment is applied to the work without continuously heating the same.
