ABSTRACT:
A lens is manufactured by hardening soft material filled inside a molding tool by cooling. The lens includes a convex lens portion having an optical axis, and a marking portion located outside of an effective diameter of the lens portion. The shape or the position of the marking portion is set to prevent deformation of the marking portion by contact with the molding tool due to shrinkage of the material during cooling.
