Abstract

The invention discloses an optical imaging lens group, the optical imaging lens group comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens in sequence from an object side to an image side along an optical axis, the object side surface of the second lens is a convex surface; the fourth lens has negative focal power, and the object side surface of the fourth lens is a convex surface; the object side surface and the image side surface of the fifth lens are convex surfaces; the sixth lens has negative focal power; the distance TTL from the object side surface of the first lens to the imaging surface of the optical imaging lens group on the optical axis, the effective focal length f of the optical imaging lens group and the entrance pupil diameter EPD of the optical imaging lens group meet (TTL / f) * EPDlt, 2.06 mm in thickness; and the maximum half field angle Se -FOV of the optical imaging lens group satisfies Se -FOVgt; the temperature is 50 DEG C;

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to an optical imaging lens group. Background technique [0002] Nowadays, smart phones are not only a communication device, but also a facility for people's entertainment, especially the camera capabilities of mobile phones are the focus of attention. Although the ordinary standard lens can image clearly in most cases, when shooting tall buildings or mountains and other vast scenes, the standard lens can only capture a part of the scene, and cannot show the grandeur and majesty of the scene. The wide-angle lens has a large viewing angle and a long depth of field, which can not only image the complete scene on the image surface, but also exaggerate the foreground, express the sense of distance and distance of the scene, and increase the spatial depth of the photographic picture and the appeal of the picture. In order to better meet the application requirements of wide-angl...
