The optical glass lens has been a key component in electronic-optical products. In contrast to traditional grinding technology, hot embossing forming technology of glass lens has shorten the manufacturing time and become one of the most important process to meet the demand of optical glass lens in mass-production market. This research had been divided into two steps on the research of hot embossing forming of optical glass lens. In the first step, two kinds of preforms prepared by lapping and polishing process were tested to obtain preliminary hot embossing parameters. In the second step, commercially available glass beads (optical grade) were used and optimal hot embossing parameters were sought to obtain glass lens. Two different materials for mold inserts and several coatings for the die surface were tested during hot embossing process. The geometrical accuracy and surface roughness of final products were examined and glass lens with optical grade requirement was met.
