Abstract (en)
[origin: WO2005050264A2] The invention divides the lens focusing process into two or more surfaces that incorporated multiple curved axial optic elements on each surface. The axial optics may be manufactured by molding, machining, or by suspended film. If suspended film is used, then both sides of an optic may have a suspended film that is transparent. Alternatively, one side of the suspend film optic may use a reflective film.
