OPTICAL IMAGING LENS ASSEMBLY, IMAGE CAPTURING UNIT AND ELECTRONIC DEVICE

The invention discloses an optical imaging lens assembly. The optical imaging 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 second lens element has positive refractive power. The third lens element has negative refractive power. The fifth lens element has positive refractive power. The sixth lens element has negative refractive power. At least one surface among object-side surfaces and image-side surfaces of the six lens elementsof the optical imaging lens assembly has at least one critical point in an off-axial region thereof and is aspheric. 本发明公开种光学影像撷取镜组，包含六片透镜，其由物侧至像侧依序为第透镜、第二透镜、第三透镜、第四透镜、第五透镜与第六透镜。第二透镜具有正屈折力。第三透镜具有负屈折力。第五透镜具有正屈折力。第六透镜具有负屈折力。第透镜、第二透镜、第三透镜、第四透镜、第五透镜与第六透镜的所有物侧表面及所有像侧表面中至少表面为非球面且于离轴处具有至少临界点。当满足特定条件时，光学影像撷取镜组能同时满足大光圈、广视角及微型化的需求。本发明还公开具有上述光学影像撷取镜组的取像装置及具有取像装置的电子装置。
