A conical stage lens which receives a convergent coni cal beam of diffused sunlight and emits a concentrated circular whole beam. The lens is mounted on a tapered hexagonal base which allows the lenses to be mounted side by side to form a sphere. The concentrated beams are projected onto a heating element at the center of the sphere.
