AI Technical Summary

Technical Problem

Existing technologies struggle to provide wide-angle camera lenses with excellent optical performance while meeting the demands for miniaturization and high pixel count, particularly in terms of ultra-thinness and image quality.

Method used

An eight-lens camera optical lens was designed. By optimizing parameters such as focal length, radius of curvature, on-axis distance, and thickness of each lens, specific relationships were satisfied to achieve the design requirements of wide-angle and ultra-thin design. Furthermore, the imaging quality was improved through reasonable allocation of optical power and selection of lens materials.

Benefits of technology

It achieves wide-angle and ultra-thin camera lenses with excellent optical performance, suitable for high-pixel camera elements, especially mobile phone camera lenses and web camera lenses, with good image quality and low sensitivity.
