ABSTRACT:
A method of making a gradient index optical element includes a step in which a comonomer mixture is prepared. The comonomer mixture is then injected into a preformed forming body. The forming body containing therein the comonomer mixture is subsequently processed at a constant temperature to cause the forming body to swell. Finally, the comonomer mixture contained in the swelled forming body is polymerized.
