　　Precision glass molding(PGM)technology is a cost-effective manufacturing process for high precision optical elements with complex surfaces.With this processing technology,one or more pieces of lenses may be produced through one-step molding.Due to the high efficiency of the replicative process,PGM has found wide applications in high volume optical elements production.At present,it has been well developed and widely used in mass industry production in Japan and South Korea,but in China PGM technology research is still in the elementary stage.
