Axial symmetric molding glass lens, mold assembly for an axial symmetric molding glass lens, method for manufacturing a mold assembly for an axial symmetric molding glass lens and method for manufacturing an axial symmetric molding glass lens

摘要

An axial symmetric molding glass lens has a central longitudinal axis, a lens surface, an annular intermediate area and a mounting flange area. The lens surface is axial symmetric around the central longitudinal axis and is curved. The annular intermediate area is curved and axial symmetric, is formed around the lens surface and has a radius of curvature having a continuously vary modulus that decreases as the radius of curvature approaches the annular intermediate area. The mounting flange area is formed around and connects smoothly to the annular intermediate area. The axial symmetric molding glass lens has fine precision, a high production rate and a low cost.
