AI Technical Summary

Technical Problem

Existing AR optical solutions struggle to achieve an effective balance between thinness, wide field of view, high imaging quality, and mass production costs, resulting in bulky and heavy lenses with insufficient aberration correction capabilities, which affects imaging uniformity and viewing experience.

Method used

It employs a five-element alternating positive-positive-negative-positive-negative optical power lens combination, combined with aspherical lenses and glass-plastic hybrid structure, and optimizes light incidence through aperture to synergistically correct aberrations such as spherical aberration, field curvature, and distortion, thereby achieving a large field of view and high resolution imaging effect.

Benefits of technology

It achieves large field of view, low distortion, and high resolution imaging within a compact optical structure, reduces lens size and weight, improves imaging uniformity and clarity, meets the lightweight requirements of head-mounted AR devices, and reduces production costs.
