Abstract
A dish-shaped, radiant energy collector comprises a thin, concave, thermoplastic cover having a reflective layer of metallization vapor deposited on the convex side thereof. A coating of foamed resin is applied to the metallization in order to render the collector self-supporting. Struts or a layer of honeycomb cardboard and/or fiberglass may be introduced into the sandwiched composite to provide further structural rigidity. The cover is produced by forming a flat sheet of acrylic plastic which is transparent to the wavelengths of interest.
