Abstract: Systems and methods are disclosed for augmented reality devices with prescription lenses. An example augmented reality device may include a frame and a lens coupled to the frame. The lens may include a prescription lens configured to refract light, the prescription lens having a first index of refraction value, a waveguide encapsulated in the prescription lens, the waveguide having a second index of refraction value, and a first coating layer disposed on a first side of the waveguide, the first coating layer having a third index of refraction value. The third index of refraction value may be less than the first index of refraction value, and the first index of refraction value may be less than the second index of refraction value.

Abstract: Light weight ophthalmic lenses include a curved back lens attached to a curved front lens assembly having a functional element. An ophthalmic lens includes a curved front lens assembly and a curved back lens. The curved front lens assembly has an essentially constant thickness, forms an external world-side convex surface of the ophthalmic lens, and includes a functional element operable to modify an image of a real world scene viewed via the ophthalmic lens. The curved back lens forms an external user-side surface of the ophthalmic lens, has a world-side convex surface that is shaped complementary to and interfaced with the front lens assembly, and provides a prescribed vision correction.

Abstract: An assembly for use in a projection system includes a plurality of optical elements, such as one or more mirrors, a light engine, and a screen, and a monolith. The optical elements are coupled to the monolith to provide a central element of reference, thereby enabling alignment based on the central element of reference.

Abstract: A transport tray for a coiled fiber including one or more coils of fiber and end portions extending from the coils. The transport tray comprises a base and a receptacle disposed on the base to receive the coils of fiber therein. The receptacle may have a circular shape configured to retain the coils without violating the minimum bend radius of the fiber. A locking mechanism may be provided to secure the coiled fiber in the receptacle. The tray may includes one or more retainers to secure the end portions of the fiber, including fibers having any one of a range of diameters, in one or more desired positions. The tray may also include two or more fiber end retainers interchangeably supported on the base to retain fiber ends having different shapes and sizes. A plurality of registration features may be provided to facilitate transporting and positioning the tray at one or more process stations or tools.

Abstract: Methods and apparatus for automatically processing an optical fiber to create a fiber coil. In one embodiment, the fiber is wound about a continuously curved winding surface. In another embodiment, the winding surface ensures that a minimum bending radius of the optical fiber is not violated. In another embodiment, the fiber is wound about a rotating winding surface including a gripper spaced from the winding surface and rotatable therewith. In another embodiment, the coil is transferred to a transport medium comprising an engagement feature that engages the coil. In another embodiment, the coil is stripped from the winding surface and inserted in the transport medium without gripping the fiber. In another embodiment, the fiber is wound about a mandrel and stripped by moving the coil relative to the mandrel axis.

Abstract: A work pallet for processing optical fiber. The work pallet may be configured to manage lengths of optical fiber for an automated manufacturing process. In this regard, the pallet may be configured to organize and maintain individual fibers in one or more desired positions to facilitate a manufacturing process. For example, the pallet may be employed for an automated fusion splicing process in which pairs of optical fibers are spliced to each other to establish an optical circuit. The pallet presents a platform on which corresponding fibers of an optical fiber module or other device may be arranged in an organized fashion for fiber preparation, fusion splicing, fiber recoating, post-processing storage and the like. The pallet may employ a cross-lacing arrangement in which the fibers extend in opposite directions across the pallet to control fiber slack associated with subsequent fusion splicing or other processing of the fiber pairs.

Abstract: A method and apparatus for processing of optical fibers, including optical fibers that are part of an optical device. In one illustrative embodiment, one or more optical fibers may be secured to a work pallet that is moved within a processing system before, during and/or after processing of the fibers. Optical fibers may be picked from the work pallet and processed while a portion of the fibers remains secured to the work pallet. Two or more processes may be performed on a fiber for each pick of the fiber from the work pallet. Optical fibers may be handled by gripping devices that include one curved clamping surface and two planar surfaces. Gripping devices may operate in open, closed and contain states when handling optical fibers.
