光学成像系统
摘要：
提供一种光学成像系统，其包括：第一透镜，具有负屈光力、呈凸面的物方表面以及呈凹面的像方表面；第二透镜，具有正屈光力；第三透镜，具有负屈光力；第四透镜，具有正屈光力；第五透镜，具有负屈光力；以及第六透镜，具有正屈光力。第六透镜的像方表面具有拐点。从物方朝向成像面顺序地设置第一透镜至第六透镜。
摘要（英）：

An optical imaging system includes a first lens having a negative refractive power, a convex object-side surface and a concave image-side surface; a second lens having a positive refractive power; a third lens having a negative refractive power; a fourth lens having a positive refractive power; a fifth lens having a negative refractive power; and a sixth lens having a positive refractive power. An image-side surface of the sixth lens has an inflection point. The first through sixth lenses are disposed sequentially from an object-side toward an imaging plane.
