ABSTRACT:
Embodiments related to the fabrication of a light guide are provided. One disclosed embodiment comprises extruding a thermoplastic polymer through a die to form an extrusion, machining the extrusion to one or more fixed dimensions, and maintaining a face of the extrusion in contact with a heated mold surface to soften or melt the face of the extrusion while applying pressure to the extrusion.
