    摘要： A method comprising: adhering a first lens (24) to a second lens (22) such as to form a combined lens (20) having a given optical design, the adhering comprising: placing the first lens (24) and the second lens (22) in respective first and second pressure chambers (71, 72), with an adhesive layer (73) disposed between the first lens (24) and the second lens (22), pressure within each of the first and second pressure chambers (71,72) being independently controllable; bringing a convex surface of the first lens (24) into contact with the adhesive layer (73), such that a central region (76) of the convex surface of the first lens (24) initially contacts the adhesive layer (73), and contact between the convex surface of the first lens (24) and the adhesive layer (73) subsequently radiates outwardly from the central region (76) of the convex surface of the first lens (24), until the convex surface of the first lens becomes covered by the adhesive layer (73); and bringing a concave surface of the second lens (22) into contact with the adhesive layer (73), such that a central region (77) of the concave surface of the second lens (22) initially contacts the adhesive layer (73), and contact between the concave surface of the second lens (22) and the adhesive layer (73) subsequently radiates outwardly from the central region (77) of the concave surface of the second lens (22), until the concave surface of the second lens (22) becomes covered by the adhesive layer (73).
