Based on the previously established hot embossing technique for optical glass, this proposal is focused on improving the existing experimental apparatus and developing a new optical glass hot embossing machine with the aims of low-cost and suitable for industrial application. Although optical glass hot embossing process can be proceeded by current experimental apparatus so far, the displacement precision and parallelism of current servo controlled compression tester cannot be satisfied for the optical component requirement. Furthermore, the forming force of hot embossing cannot be controlled precisely in vacuum, which makes forming difficult and results in high defective rate of products. On the other hand, the infrared heaters were placed in the vacuum and high temperature furnace so the life span would be reduced. In order to overcome the above disadvantages, this proposal is focused on improving the servo controlled compression tester to elevate the hot embossing precision, and tries to overcome controlling the forming force of hot embossing in vacuum by putting the load cell in the vacuum furnace. Moreover, infrared heaters are placed outside of the vacuum furnace. By the property which infrared rays can pass through quartz tube to heat the molds and the optical glass, the infrared heaters are in lower temperature environment and the life spans can be elevated. By industry-university cooperation, this proposal is based on the existing development ability of optical glass hot embossing apparatus to develop a new optical glass hot embossing machine to meet the industrial application requirement with cooperative factory. Furthermore, the key technique of optical glass hot embossing on machine will be established and transferred, so the cooperation company can obtain the territory of optoelectronic industry and the technical and competitive abilities of the whole industry can be upgraded.
