US 2013/0258503 A1 · OPTICAL LENS ASSEMBLY AND A LASER WELDING METHOD USED FOR THE SAME

Abstract

The present invention provides an optical lens assembly, comprising: at least an optical lens; a lens barrel within which the at least one optical lens is placed; and a retainer placed within the lens barrel; wherein the optical lens is arranged such that an optical axis thereof is aligned with a central axis of the lens barrel; and wherein the retainer is arranged such that a peripheral surface thereof is in contact with an inner wall of the lens barrel and a bottom surface thereof is pressed against one surface of the optical lens. A laser beam is used to irradiate the peripheral surface of the retainer to cause a temperature rise at an area where the retainer is in contact with the lens barrel to reach a welding temperature, thereby welding the retainer to an inner side of the lens barrel.
