A multicore fiber light transfer system includes a multicore fiber having a proximal end and a distal end and at least three optical cores. The multicore fiber transferring light from the proximal end to the distal end and collecting light from a target at the distal end and transferring the collected light to the proximal end. Distal optics is 3D printed near the distal end of the multicore fiber. The distal optics includes a first element having a surface that is aligned to one core of the multicore fiber with a first shape such that the first element projects the light transferred from the proximal end in a first desired direction with a first desired beam shape and having a second element comprising a surface that is aligned to another core of the multicore fiber with a second shape such that the second element collects light from a desired location on the target.

METHOD FOR INJECTION MOLDING PLUS POWER LENS ELEMENTS
A method for injection molding of a plus power lens element comprises injecting a melt of thermoplastic material comprising at least one UV absorber at a temperature higher than a glass transition temperature (Tg) of the thermoplastic material in an initial molding cavity delimited by two facing mold inserts. During the injecting, the two facing mold inserts are moved toward one another to define a final molding cavity whose volume is less than that of the initial molding cavity. After cooling and opening of the mold cavity, the plus power lens element is recovered. One of the two facing mold inserts comprises a flat surface facing the initial molding cavity, thereby to form a flat surface on one side of the plus power lens element, and the other of the two facing mold inserts comprises a concave surface facing the initial molding cavity, thereby to form a convex surface on an opposite side of the plus power lens element.
METHOD FOR INJECTION MOLDING WELD LINE FREE MINUS POWER LENS ELEMENTS
A method for injection molding of a weld line free minus power lens element comprises injecting a melt of thermoplastic material at a temperature higher than a glass transition temperature (Tg) of the thermoplastic material in an initial molding cavity delimited by two facing mold inserts, wherein the melt of thermoplastic material comprises at least one UV absorber. During the injecting, the two facing mold inserts are moved toward one another to define a final molding cavity whose volume is less than that of the initial molding cavity. After cooling and disassembling of the two facing mold inserts, the weld line free minus power lens element is recovered. One of the two facing mold inserts comprises a flat surface facing the initial molding cavity, thereby to form a flat surface on one side of the weld line free minus power lens element. The other of the two facing mold inserts comprises a convex surface facing the initial molding cavity, thereby to form a concave surface on an opposite side of the weld line free minus power lens element.

Method for fabricating a curved eyepiece
Techniques and mechanisms for fabricating an eyepiece from a lens blank including blank bodies that are bonded to each other. In an embodiment, the blank bodies are formed by injection molding and adhered to one another. Fabrication of the eyepiece includes variously machining the blank bodies to shape respective lens bodies of the eyepiece. One or more blocking structures are coupled to reinforce the lens blank during at least part of such machining. In another embodiment, any blocking structures that are to resist forces of a particular machining process are coupled only indirectly to one of the blank bodies.
Optical light guides and methods of manufacturing the same
Fabricating light guide elements includes forming a first portion of the light guide element using a replication technique (104), and forming a second portion of the light guide element using a photolithographic technique (106). Use of replication can facilitate formation of more complex-shaped optical elements as part of the light guide element. The replication process sometimes results in the formation of a yard, or excess replication material, which may lead to light leakage if not removed or smoothed over. In some instances, at least part of the yard portion is embedded within the second portion of the light guide element, thereby resulting in a smoothing over of the yard portion.
