AI Technical Summary
Technical Problem
Existing zoom lenses have a slow response time and mostly use manual zoom or drive motors, which cannot meet the requirements of high definition and lightweight design.
Method used
It adopts an eight-element structure that combines seven plastic aspherical lenses with liquid lenses. By controlling the total optical length and the lens focal length ratio, it achieves automatic focusing and optimizes the optical design in combination with liquid lenses.
Benefits of technology
It achieves miniaturization of optical imaging lenses, fast focusing speed, high image clarity, meets shooting needs at different object distances, and reduces production costs.

Abstract
本发明涉及成像镜头领域，具体而言，涉及一种光学成像镜头，从物侧至像侧沿一光轴依次包括第一透镜、第二透镜、光阑、第三透镜、第四透镜、第五透镜、第六透镜和第七透镜；所述第一透镜至第七透镜各自包括一朝向物侧且使成像光线通过的物侧面以及一朝向像侧且使成像光线通过的像侧面，所述第二透镜和光阑之间设置有液态透镜，利用液态镜头对光学成像镜头进行自动调焦，相应速度较快；在无穷远的物距下，在空间频率达到125lp / mm时，中心视场的MTF均大于0.45，而在1m的物距下，在空间频率达到125lp / mm时，中心视场的MTF同样均大于0.45，调焦效果良好，满足不同物距下的拍摄需求。
