ABSTRACT:
A radiation collector having a flexible reflective wall which is deflected to a curved preferably paraboloidal configuration by application of differential pressures to opposites sides of the wall. In one form of the invention, the reflective wall forms the back wall of an inflatable bag having a forward flexible wall through which radiation from a source passes to the interior of the bag for reflection by the rear wall toward an axis of the device. In another form of the invention, the reflective flexible wall is the front wall of a vacuum chamber and is deflected rearwardly by the differential between a subatmospheric pressure in the chamber and atmospheric chamber at the front of the wall. A structure extending essentially circularly along the periphery of the flexible reflective wall preferably restrains the peripheral position of the wall against constriction radially inwardly upon application of the pressure differential to the wall, in a relation causing the wall to assume an ultimate configuration corresponding more closely to that or a true paraboloid than if the restraining structure were not present. Desirably, the pressure differential is predetermined and regulated to give the reflective wall a substantially exactly paraboloidal shape.
