Abstract
An imaging lens assembly of an optical verification system with a FOV greater than 120 degrees, and includes optical lenses from an object side to an image side. The one of the optical lens being the closest to the object side includes: an object side surface and an image side surface of an optical zone; an object side surface of a non-optical-zone surrounding the object side surface of the optical zone; an image side surface of a non-optical zone surrounding the image side surface of the optical zone; and a first connection portion disposed between the image side surface of the optical-zone and the image side surface of the non-optical zone, wherein a first angle between a tangential direction of a surface of the first connection portion and the radial direction is in a range of 15 to 50 degrees.
