Patent Images

1. a kind of optical imaging lens, sequentially included along an optical axis by an object side a to image side one first lens, one second lens,One the 3rd lens, one the 4th lens, one the 5th lens, one the 6th lens and one the 7th lens, each lens all have a direction shouldObject side and make imaging light by object side and one towards the image side and make imaging light by image side surface, the optical imageryThe lens that camera lens has refractive index only have above-mentioned seven lens,Wherein,One circumferential area of the image side surface of second lens is concave surface;

  • One circumferential area of the object side of the 3rd lens is concave surface;

    One circumferential area of the object side of the 6th lens is concave surface;

    One optical axis region of the image side surface of the 6th lens is convex surface,And the optical imaging lens meet following conditional:

    V1- (V3+V4)≤

    - 10.000,Wherein, V1 is the Abbe of first lens, and V3 is the Abbe of the 3rd lens, and V4 is the 4th lensAbbe.
