These fire-polished aspheric lenses are glass lenses manufactured by a simple moulding process and polished by heating just enough to melt the surface and allow surface tension to smooth out defects. Usually these lenses have a very large diameter compared with the focal length. Fire polished aspheric lenses have large apertures so are ideal for light collecting applicatons such as condenser lenses in LED based projectors.  The second face of the plano-convex type is optically polished for improved quality.

Knight Optical stock a full range of both thermally toughened aspheric lenses and un-toughened fire polished aspheric lenses. For higher quality applications we also sell uncoated and AR coated precision aspherics available to purchase directly from this site.
