Abstract
A device for protecting the surfaces of objects from the effects of radiation, particularly highly concentrated solar radiation, is produced by utilizing the property of quartz glass not to absorb any radiation in the range of the solar spectrum. When the quartz glass is impinged upon by sunlight, the major part of the radiation, regardless of the thickness of the quartz glass body, is transmitted by the latter, and a small portion of the radiation (<10%) is reflected at the surface. By superimposing a plurality of quartz glass bodies, the required radiation protection is produced in that the preponderant portion of the radiation is reflected stepwise in this way. The quartz glass may take the form of plates, of fibers interlaced into a batting, or of a fabric made of quartz glass filaments.
