| abstract | MACRO-GRADIENT OPTICAL DENSITY TRANSMISSIVE LIGHT CONCENTRATORS, LENSES AND COMPOUND LENSES OF LARGE GEOMETRY, AND FABRICATION THEREOF ABSTRACT OF THE DISCLOSURE Gradient optical density transmissive light directing devices (24, 26, 28, 30) and fabrication thereof are dis-closed herein. Examples of such devices include concen-trators, lenses and compound lenses. The present inven-tion teaches a process for the fabrication of glass light transmitting devices having a chosen gradient in index of refraction either bidirectionally (radially and longitu-dinally relative to an optical axis) or in three dimen-sions. The present invention further describes the design of several interesting optical devices by particular choices of the gradient in the index of refraction there-of. Such articles have numerous uses in the optics, opti-cal fiber and solar technology industries for the purposes of designing compound lens systems using a single, inte-gral lens, coupling light into fibers and for concentrat-ing and directing light from a source having a significant angular variation to an energy collecting and/or conver-sion devices such as a photovoltaic cell, to name but a few application. |
