Optical imaging lens assembly

Abstract

An optical imaging lens assembly includes, sequentially along an optical axis from an object side to an image side: a first lens, having a negative refractive power, an image-side surface of the first lens being a concave surface; a second lens, having a positive refractive power, an object-side surface of the second lens being a convex surface; and a third lens, having a refractive power, an object-side surface of the third lens being a convex surface. A Half of a diagonal length ImgH of an effective pixel area on an image plane of the optical imaging lens assembly, an effective focal length f of the optical imaging lens assembly and an entrance pupil diameter EPD of the optical imaging lens assembly satisfy: 3 mm<ImgH×f/EPD<4 mm. A maximal field-of-view FOV of the optical imaging lens assembly and the effective focal length f of the optical imaging lens assembly satisfy: 1 mm<tan(FOV/2)×f<2 mm.
