Abstract
In some examples, a method may include applying a force to the curved surface of the lens assembly using at least one deformable element to adhere the lens assembly to a functional stack to form a laminated combination. Example methods may be used to fabricate apparatus such as an augmented reality or virtual reality device using the laminated combination. The curved surface may have a curvature based on an ophthalmic prescription for a user. Example methods and apparatus may relate to the fabrication of head-mounted devices including prescription-based optics. Other devices, methods, systems, and computer-readable media are also disclosed.
Claims20
A method comprising:
- locating a lens assembly proximate a functional stack, the lens assembly having a curved surface;
- applying a force, by an arrangement of actuators, to the curved surface of the lens assembly using a deformable element comprising a plurality of pogo pins, wherein an amount of force applied by each pogo pin in the plurality of pogo pins is individually controllable by the arrangement of actuators;
- adhering the lens assembly to a functional stack using the force to urge the lens assembly against the functional stack to form a laminated combination;
- and
- fabricating an augmented reality or virtual reality device using the laminated combination, wherein:
- the functional stack comprises at least one additional lens, at least one polarizer, and at least one beamsplitter.
An apparatus comprising:
- a sample holder configured to support a lens assembly and a functional stack in positional registration, wherein the lens assembly has a curved surface and a planar surface;
- a deformable element comprising a plurality of pogo pins;
- and
- an arrangement of actuators configured to apply a force to the curved surface of the lens assembly using the deformable element to thereby adhere the planar surface of the lens assembly to a surface of the functional stack, wherein an amount of force applied by each pogo pin in the plurality of pogo pins is individually controlled by the arrangement of actuators.
