Patent attributes
The application discloses an optical imaging lens assembly including, sequentially from an object side to an image side, a first lens having a positive refractive power with a convex object side surface and a concave image side surface; a second lens having a negative refractive power with a convex object side surface and a concave image side surface; a third lens having a refractive power; a fourth lens having a refractive power with a concave image side surface; a fifth lens having a refractive power; a sixth lens having a negative refractive power with a convex object side surface and a concave image side surface. An effective focal length f, an entrance pupil diameter EPD, half of a maximum field of view HFOV and a curvature radius R8 of the image side surface of the fourth lens satisfy f/EPD<2.0, 3.8 mm<f*TAN(HFOV)<5 mm, and R8≥500 mm.
