ABSTRACT:
A cylindrical arc reflector of electromagnetic radiation which is a rectangular sheet of material having a radiation reflective surface composed of longitudinal segments that reflect substantially all of the impingent radiation to a longitudinal focal line when the reflective surface is held in the form of a concave cylindrical arc by a pressure differential. The sheet is mounted by its longitudinal edges with its transverse edges movably sealed so as to form an enclosure into which a low vacuum is introduced to create the form holding pressure differential. The reflector is particularly adaptable for use in a solar energy collection apparatus that is constructed using a support structure that does not include the precisely accurate shape of the reflective surface.
