PLASTIC REFLECTIVE WAVEGUIDE MANUFACTURING
A plastic reflective waveguide is manufactured using a soft transfer stamp formed in a first mold using a liquid injection molding process to provide the stamp with parallel wall surfaces having a zero degree draft angle. The soft transfer stamp is placed as an insert in a second mold utilized in a multi-stage thermoplastic injection molding process. A first thermoplastic injection molding stage molds a base part of the plastic reflective waveguide having parallel wall surfaces with a zero degree draft angle. The soft transfer stamp is removed from the second mold and a partially-reflective coating is applied to the base part. A second thermoplastic injection molding stage is utilized to create a secondary part of the plastic reflective waveguide. The raw plastic reflective waveguide is ejected from the second mold and subjected to additional manufacturing processes to realize a finished part meeting design requirements for size and form factor.

A PROCESS FOR MANUFACTURING AN OPHTHALMIC LENS EQUIPPED WITH AN INSERT
The invention relates to a process for manufacturing an ophthalmic lens element equipped with an insert (1), this ophthalmic lens element comprising a front face and a back face, comprising steps consisting in: providing a first portion or intermediate product (2, 2) made of a first material comprising a first and second frontal face (2A, 2B, 2A, 2B), said second face forming the back or front face of said ophthalmic lens element; placing the insert (1) on said first face of said intermediate product; depositing a second material in liquid form on said first face of the intermediate product (2, 2) so as to cover at least partially said insert with said second material; and solidifying said second material in order to form an integral second portion (4) of said intermediate product. According to the invention, said first material is organic.
Methods of forming a TIR optical fiber lens
Methods of forming a total-internal-reflection (TIR) optical fiber lens are disclosed. The methods include heating an end of an optical fiber with a defocused infrared laser beam to form a bulbous tip having a curved outer surface that defines a lens surface. The bulbous tip is laser cleaved to define a TIR facet. Light traveling in the fiber diverges at an effective fiber end and is reflected by the TIR facet through the lens surface to form an image at an image plane.
