摄影光学镜头及取像装置
摘要：
本发明公开一种摄影光学镜头及取像装置，摄影光学镜头包含六片透镜，由物侧至像侧依序为第一透镜、第二透镜、第三透镜、第四透镜、第五透镜与第六透镜。第一透镜具有负屈折力，其像侧表面近光轴处为凹面。第二透镜像侧表面近光轴处为凸面。第四透镜材质为塑胶。第五透镜具有负屈折力，第五透镜像侧表面离轴处具有至少一反曲点。第六透镜物侧表面近光轴处为凸面，其像侧表面近光轴处为凹面，其像侧表面离轴处具有至少一反曲点，其物侧表面与像侧表面皆为非球面。第一透镜至第六透镜中间无其他内插透镜，并满足特定条件，如此，利于缩短后焦距与提高解像力。本发明还公开具有上述摄影光学镜头的取像装置。
摘要（英）：

An image capturing lens assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, and a sixth lens element. The first lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof. The second and third lens elements have refractive power. The fourth lens element has positive refractive power. The fifth lens element with negative refractive power has an object-side surface being concave in a paraxial region thereof. The sixth lens element with refractive power has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof. The image capturing lens assembly has a total of six lens elements with refractive power.
