Abstract
A method of producing a composite optical element such as lenses and optical filters is provided. The resulting product has a high quality precision surface with a relatively low production cost. A glass substrate is treated with a silanating agent to activate its surface. An organic polymer material can then be applied to the activated surface with a mold platen forming a desired exterior configuration. The organic polymer is then polymerized to form a relatively thin layer of cured organic material having the exterior desired surface configuration of the glass substrate. The composite optical product is then released from the mold in its final configuration in a relatively short time period.
