Abstract

Laser and infrared optical technologies are developed quickly recently. Small aspheric lens of φ30 to 100mm which are normally used in such optical systems are largely demanded. But computer controlled polishing technology for small batch-quantity aspheric lens is a bottle-neck technology to prevent the development of laser and infrared optical technologies. In this article, the technology of computer controlled optical surfacing (CCOS) was used to solve the problems of batch-quantity aspheric lens' polishing. First, material's removing action by computer controlled small polishing tool is detailed simulated by computer. Then, According to the simulation result, polishing correction is completed after adjusting the function of tool's resident time. Finally the accuracy of 70 mm aspheric lens (Surface shape measurement value is 0.45μm, roughness measurement value is 2.687nm) is achieved under efficient polishing with our home made model computer controlled polishing machine which has three universal driving shafts. Efficiency of small aspheric lens' batch-quantity manufacturing is remarkably improved.
