Six-Lens Camera Module with Aspherical Surfaces for Aberration Correction

The patent applies parameter changes by utilizing aspherical surfaces on the fifth and sixth lenses, which have different geometric parameters compared to traditional spherical lenses. This allows for better correction of optical aberrations and improved optical performance while maintaining a compact six-lens configuration. The aspherical surfaces enable more precise control of light paths, resolving the contradiction between device complexity and optical performance.

The patent employs aspherical surfaces on the fifth and sixth lenses, which utilize non-spherical curvature to correct optical aberrations more effectively than traditional spherical lenses. This allows the compact lens system to maintain high optical performance despite the reduced length required for portable devices. The aspherical curvature enables better control of light rays across the compact optical path.

The patent applies local quality by introducing aspherical surfaces specifically on the fifth and sixth lenses, rather than making all six lenses aspherical. This targeted approach improves optical performance where it is most needed for aberration correction, while keeping the overall device complexity manageable. The local application of aspherical surfaces optimizes the balance between performance improvement and manufacturing complexity.
