光学取像镜组、取像装置及电子装置
摘要：
本发明公开一种光学取像镜组，包括五片透镜。该五片透镜由物侧至像侧依序为第一透镜、第二透镜、第三透镜、第四透镜与第五透镜。第一透镜像侧表面于近光轴处为凹面。第二透镜具有负屈折力，其像侧表面于近光轴处为凹面。第三透镜具有正屈折力，其像侧表面于近光轴处为凸面。第四透镜具有正屈折力。第五透镜具有负屈折力。当满足特定条件时，光学取像镜组能同时满足广视角、微型化、抗环境变化及高成像质量的需求。本发明还公开具有上述光学取像镜组的取像装置及具有取像装置的电子装置。
摘要（英）：

An optical imaging lens assembly includes five lens elements which are, 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 and a fifth lens element. The first lens element has an image-side surface being concave in a paraxial region thereof. The second lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof. The third lens element with positive refractive power has an image-side surface being convex in a paraxial region thereof. The fourth lens element has positive refractive power. The fifth lens element has negative refractive power.
