Abstract

A method of manufacturing a composite optical element, in which method a lens material of plastic is formed on a lens. The lens has a first optical surface and a second optical surface, and a lateral edge tilted at an angle relative to the perpendicular center line of the lens. The lens material is formed into a lens medium which covers only the first optical surface and a portion of the lateral edge of the lens. A tight binding is then established between the lens and the lens medium, which is formed of the lens material.
