Abstract
A lens structure and method for manufacture of such a lens. A lens element has multiple sawn planar faces between image forming surfaces so the lens element has a polygonal cross section. The manufacture includes the step of utilizing oversized conventional cylindrical lens elements and other optical elements formed into lens systems. The faces are sawn to reduce the overall size. The sawing can be applied to integral lens elements or assemblies or lens arrays.
