Abstract

The invention relates to a seven-piece type large-aperture high-pixel optical imaging lens. The seven-piece type large-aperture high-pixel optical imaging lens sequentially comprises a diaphragm, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens from an object side to an image side; the optical imaging lens satisfies the following relational expressions: f1 / |f2|<0.5, 1<(R1+R2) / (R3+R4)<2.5, and R10 / f<3; and f1 is the focal length of the first lens, f2 is the focal length of the second lens, R1 is the curvature radius of the object side surface of the first lens, R2 is the curvature radius of the image side surface of the first lens, R3 is the curvature radius of the object side surface of the second lens, R4 is the curvature radius of the image side surface of the second lens, R10 is the curvature radius of the object side surface of the fifth lens, and f is the focal length of the optical imaging lens. According to the seven-piece type large-aperture high-pixel optical imaging lens, the high imaging quality can be maintained under the conditions of effectively shortening the system length and improving the pixel.
