Paper Abstract
Precision glass compression molding is an attractive approach to manufacture small precision optics in large volume
over traditional manufacturing techniques because of its advantages such as lower cost, faster time to market and being
environment friendly. In order to study the relationship between the surface figures of molded lenses and molding
process parameters such as temperature, pressure, heating rate, cooling rate and so on, we present some glass
compression molding experiments using same low Tg (transition temperature) glass material to produce two different
kinds of aspheric lenses by different molding process parameters. Based on results from the experiments, we know the
major factors influencing surface figure of molded lenses and the changing range of these parameters. From the
knowledge we could easily catch proper molding parameters which are suitable for aspheric lenses with diameter from 10mm to 30mm.
