Claim 16:
17. An assembly method for optical lens, comprising:
pre-positioning a first lens component and a second lens component so that at least one second lens sheet of the second lens component and at least one first lens sheet of the first lens component together form an imageable optical system, the at least one first lens sheet being mounted in a first lens barrel of the first lens component, and the at least one second lens sheet being mounted in a second lens barrel of the second lens component, and forming a first gap and a second gap between the first lens component and the second lens component, wherein the first gap is closer to an outer side of the optical lens than the second gap;
adjusting and determining a relative position of the first lens component and the second lens component based on active alignment; and
bonding the first lens component and the second lens component by an adhesive;
wherein the adhesive includes a first adhesive located in the first gap and a second adhesive located in the second gap;
wherein the second adhesive is interposed between and directly bonding a top surface of the second lens barrel and a bottom surface of the first lens sheet, or interposed between and directly bonding a bottom surface of the first lens barrel and a top surface of the second lens sheet.
