Abstract
An optical imaging lens proofed against field curvatures, in an imaging module, and the module being used in an electronic device, is, from an object side to an image side, composed of a first lens with a positive refractive power, a second lens, a third lens, a fourth lens with a negative refractive power, a fifth lens, and a sixth lens with a negative refractive power. The optical imaging lens satisfies the formula −3 mm−1<FNO/f6<−0.1 mm−1, −0.065 mm/°<f6/FOV<−0.03 mm/°, wherein FNO is a F-number of the optical imaging lens, f6 is a focal length of the sixth lens, and FOV is a maximum field of view of the optical imaging lens.
