| abstract |
A method of fabricating an elongate light guide (70) includes providing a moving mold assembly (30) with at least two mold parts (32A, 34A), wherein the mold parts have an engaged portion (32A, 34A) and a non-engaged portion (33, 33A). The mold parts are moved such that the non-engaged portions (33, 33A) move in a first direction (A, B) and the engaged portions (32A, 34A) move in a second direction (C) different from the first direction to form an elongate regenerated mold cavity (37, 39) having a longitudinal axis, wherein the cavity comprises a molding surface (54) with at least one structure (52) transverse to the longitudinal axis. A thermosettable material is introduced into the cavity (37, 39) and at least partially polymerized in the cavity (37, 39) to form a light guide (70) therein. The light guide is then removed from the mold assembly. |
