Problems solved by technology

At present, the superposition of optical waveguide lenses is mainly bonded by a pressure-sensitive adhesive, such as PSA (pressure sensitive adhesive, pressure-sensitive adhesive), but PSA has the problem of uneven film thickness control, which affects the lamination. The surface parallelism of the combined optical waveguide lens will lead to poor performance of the restored contrast (Modulation Transfer Function, MTF) of the optical waveguide lens

Abstract

The invention discloses an optical waveguide lens overlapping structure and a manufacturing method thereof, wherein the optical waveguide lens overlapping structure comprises a first lens and a second lens which are overlapped, and an ultraviolet light curing adhesive layer is clamped between the first lens and the second lens; and the ultraviolet light curing adhesive layer comprises a base adhesive and particles filled in the base adhesive, and the ultraviolet light curing adhesive layer is used for bonding the first lens and the second lens. According to the technical scheme, the surface parallelism of the optical waveguide lens overlapping structure is good, and the reduction contrast performance is good.

Description

technical field [0001] The invention relates to the technical field of preparation of optical waveguide lenses, in particular to a superimposed structure of optical waveguide lenses and a manufacturing method thereof. Background technique [0002] AR (Augmented Reality, Augmented Reality) technology is to generate virtual objects that do not exist in the physical world through computer graphics technology and visualization technology, and is used to enrich the user's perception. Among them, the optical waveguide lens with transparency effect and imaging / light guiding effect is the most critical component for the implementation of AR hardware. At present, the superposition of optical waveguide lenses is mainly bonded by a pressure-sensitive adhesive, such as PSA (pressure sensitive adhesive, pressure-sensitive adhesive), but PSA has the problem of uneven film thickness control, which affects the lamination. The surface parallelism of the combined optical waveguide lens will ...
