Optical Application of Diamond Turning Process
광학 응용을 위한 다이아몬드 터닝 가공
Abstract
Diamond turning machines have, been used for the processing of surface like a mirror with the control scheme of minimizing shape error, Ultra-precision diamond fuming is applied to produce highly precision optical components required not only a high machining accuracy but also a good surface roughness. Al-6061 is widely used as optical parts such as laser reflector's mirror or multimedia instrument. In this study, thermal-imaged Al flat mirrors are fabricated by SPDT. The surface roughness 3.472 nm Ra, power 2 fringe(at 632.8 nm) and irregularity 1 fringe(at 632.8 nm) for form waviness of thermal-imaged Al flat mirror are very satisfied to the required specification in industry.
