Application: 3d print microstructures for ar waveguide packaging and protection (Patent ID: US20240142694A1)
The patent filed by Meta Platforms Inc. describes techniques and systems for stacked optical assemblies using micro spacers positioned between optical substrates to maintain a specific gap height. These micro spacers can be fixedly attached to one or both substrates and may create a vacuum or be filled with a material of a certain refractive index. The patent also details the arrangement of micro spacers in non-uniform patterns, their fabrication using 3D printing processes, and specific dimensions such as layer thickness and diameter.
Furthermore, the patent outlines various embodiments of the stacked optical assembly, including different shapes of micro spacers, the use of specific materials like UV curable resin, and the optical properties of the spacers. The disclosed assembly can be applied to optical waveguides, dimming layers, eye tracking layers, and other optical components. Additionally, the patent discusses the transmission rate of the materials used, the height variations of the micro spacers to prevent collisions, and the specific refractive indices of the materials involved.
