열 영상 광부품의 초정밀가공기술 개발

Diamond turning machines have, been used for the processing of surface like a rumor with the control scheme of minimizing shape error Ultra-precision diamond turning 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 3472 ㎚ Ra, power 2 fringe(at 632 8 ㎚) and irregularity 1 fringe(at 6328 ㎚) for form waviness of thermal-imaged Al flat mirror are very satisfied to the required specification in industry
