    • The invention discloses a six-piece optical lens for capturing image and a six-piece optical system for capturing image. In order from an object side to an image side, the optical lens along the optical axis comprises a first lens with a positive refractive power having a convex object-side surface; a second lens with a refractive power; a third lens with a refractive power; a fourth lens with a refractive power; a fifth lens with a refractive power; and a sixth lens with a negative refractive power having a concave object-side surface; and at least one of the image-side surface and object-side surface of each of the sixth lens element has inflection points and both of the image-side surface and object-side surface of the sixth lens element are aspheric. The optical lens can increase aperture value and improve the imagining quality for use in compact cameras.
    • 本发明公开了一种用于拍摄图像的6片光学透镜和用于拍摄图像的6片光学系统。 按照从物体侧到像侧的顺序,沿着光轴的光学透镜包括具有凸的物体侧表面的具有正折光力的第一透镜; 具有屈光力的第二透镜; 具有屈光力的第三透镜; 具有屈光力的第四透镜; 具有屈光力的第五透镜; 以及具有凹面物侧表面的具有负屈光力的第六透镜; 并且第六透镜元件的每一个的图像侧表面和物体侧表面中的至少一个具有拐点,并且第六透镜元件的图像侧表面和物体侧表面都是非球面的。 光学透镜可以增加光圈值并提高在小型照相机中使用的想象质量。
