AI Technical Summary
How to achieve both compactness and high image quality in optical lenses, especially in the design of wide-angle lenses, is a challenge that current technologies struggle to balance excellent optical performance with compactness and high image quality.
The optical lens design includes a first lens group and a second lens group that can move along the optical axis. The optical lengths between the lens groups satisfy a specific relationship. By combining aspherical lenses and cemented lenses, and by rationally selecting the optical length and optical power balance of the lens groups, the lens achieves compactness and high image quality during focusing.
It achieves clear imaging between infinity and near-focus, reduces the tolerance sensitivity of optical lenses, improves image quality, and effectively corrects aberrations and distortions, thus realizing lens compactness and high resolution.
