PURPOSE:To eliminate the change of an optical characteristic according to curing of an adhesive agent by providing jig fitting parts for a centering operation of a lens cooperatively with a jig for the centering operation of the lens and for holding and curing the adhesive agent to the lens and lens frame. CONSTITUTION:The jig 11 for the centering operation of the lens 8 in the stage of adhering and fixing the lens 8 to the lens frame 9 is provided. The lens 8 is fitted in a lens containing part 12 provided to the frame 9 and is so constituted that the lens is positioned in the optical axis direction by contacting with a lens supporting part 13 provided to the part 12 to intersect orthogonally with the optical axis l direction. The bore size of the part 12 is made slightly larger than the outside diameter size of the lens 8. The lens 8 is adhered and fixed to the lens frame via the thick-layered adhesive agent 10. The fitting faces 15, 16 to be fitted to the operating part 14 in the jig 11 are provided to the inside circumferential surface of the part 12. The lens 8 is centered by fitting said faces and the operating part 14 of the jig 11 and pressing the jig 11. The adhesive agent 10 is then allowed to cure. |
