Abstract: An eyepiece for a head wearable display includes a first lens body having a first interface side in which a first recess is disposed and a second lens body having a second interface side in which a second recess is disposed. The first and second lens bodies are mated together along the first and second interface sides and the first and second recesses are aligned to form a cavity. A lightguide insert is provided that has a shape and a size to fit within the cavity defined by the first and second recesses. The lightguide insert includes an in-coupling region to receive display light into the lightguide insert and an out-coupling region to direct the display light out of the lightguide insert through the first lens body.

Abstract: An eyepiece includes a first lens body having a first interface side and a second lens body having a second interface side. At least one of the first and second interface sides includes a recess. The first and second lens bodies are mated together along the first and second interface sides to form a cavity at the recess. A lightguide insert is provided that has a shape and a size to fit within the cavity. The lightguide insert includes an in-coupling region to receive display light into the lightguide insert and an out-coupling region to direct the display light out of the lightguide insert through the first lens body.

Abstract: The present disclosure provides methods and systems for bonding multiple wafers. An example system may include a sealable chamber with a first and second substantially vertical post positioned inside of the sealable chamber. The system may also include a first latch connected to the first post via a first pin, wherein the first pin allows the first latch to rotate about the first pin. The system may also include a second latch similarly configured to the first latch. The system may also include a base plate positioned between the first and second posts. The base plate is arranged such that when a first wafer rests on the base plate and a second wafer rests on the first and second latches, moving the base plate from a first position to a second position causes a top surface of the first wafer to contact a bottom surface of the second wafer.
