Abstract

The invention discloses an optical imaging lens. The optical imaging lens sequentially comprises at least one lens and an optical annular element from an object side to an image side along an optical axis, the optical annular element is located on the side, facing the image side, of the lens closest to the image side and provided with an object side bearing face facing the object side and making contact with the lens closest to the object side. The object-side bearing surface has an object-side outer peripheral edge and an object-side inner peripheral edge, and the object-side inner peripheral edge is located between the optical axis and the object-side outer peripheral edge. The object side bearing surface is provided with at least one groove, and the at least one groove extends to the object side inner periphery along the radial direction. According to the optical imaging lens, the problem of adhesive splashing can be solved through exhaust, meanwhile, good optical imaging quality is maintained, and the optical imaging lens is technically feasible.

Description

technical field [0001] The invention relates to the field of optical devices, in particular to an optical imaging lens. Background technique [0002] In recent years, the optical imaging lens has been continuously evolving. In addition to requiring the lens to be light and thin, the imaging quality of the lens is also important. In addition to the parameters such as the surface shape of the lens or the air gap between the lenses that will affect the optical imaging quality, the lens and the optical ring element are assembled. Whether the dispensing procedure is smooth or not is also a major factor affecting the quality of optical imaging. [0003] When the conventional optical imaging lens is assembled, the lens and the supporting surface of the optical ring element are in full surface contact, that is, there is no gap between them. In the process of dispensing glue, the lens or optical ring element is bonded to the lens barrel through the adhesive, but the adhesive is easy...
