Abstract
A membrane concentrator mirror comprises a rigid, circular-segment-shaped frame-like basic body with a hermetically closed bottom wall, the basic body having a union device for connection with a conduit leading to a device for generating sub-pressure, a membrane being hermetically stretched over the basic body in such a way that it is deformable under the influence of a sub-pressure, and this membrane consisting of a plurality of membrane segments the outer end of which is limited in a circular segment shape, the membrane segments being connected with one another along radially extending rims. An improvement of the optical quality and a reliable connection of different membrane sections is to be achieved. To this effect the membrane segments are connected with one another in such a way that rigid, radially extending clamping profiles secure the radially extending outer rims by means of clamping devices.
