Zusammenfassung: | PURPOSE:To obtain a collecting lens which collects light and heat over a wide range at a low cost, by condensing solar rays, condensed through more than one lenses, to one point so that respective focal points meet through plane mirrors 2. CONSTITUTION:Lenses 1B and 1B' are arranged in contact; the circumferential lenses 1B are each provided with a plane mirror 2 at a prescribed angle theta to the optical axis, and the center lens 1B' is provided with a plane mirror 2' at right angles to the optical axis, thus permitting respective focal points meet at one point 3a. Consequently, a collecting lens which collects light and heat is obtained at a low cost. |
