These patented gradient-index cylindrical microlenses with Luneburg type refractive index distribution are drawn from a highly polished gradient-index fiber preform.
A simple tuning of the drawing process results in diffraction-limited microlenses in the shape of fibers or rods with precise diameters ...
GRADIUM® lenses are made from LightPath's proprietary axial gradient index glass. Its unique refractive qualities can be exploited to reduce spherical aberrations - resulting in performance ...
