Paper Abstract

Microstructure optical components in the form of Fresnel, TIR, microgroove, micro lens array provide a lot design freedom for high compact optical systems. It is a key factor which enables the cutting edge technology for telecommunication, surveillance and high-definition display system. Therefore, the demand of manufacturing such element is rapidly increasing. These elements usually contain high precision, tiny structure and complex form, which have posed many new challenges for tooling, programming as well as ultra-precision machining. To cope with the fast development of the technology and meet the increasing demand of the market, we have developed our own manufacturing process to fabricate microstructure optical components by way of Diamond tuning, Shaping, Raster cutting, Slow Slide Servo (SSS), Diamond milling and Post polishing. This paper is to focus on how we employed these methods to produce complex prototype of microstructure optical components and precision mold inserts which either contains aspheric lens array or freeform V grooves. The high quality finish of these surfaces meets application requirements. Measurement results are presented. Advantages and disadvantages of these methods are compared and discussed in the paper.
