A Study on the Characteristics on Ultra Precision Machining of IR Camera Mirror
적외선 카메라용 반사경의 초정밀 절삭특성에 관한 연구
Abstract
This paper is described about the technique of ultra-precision machining for a infrared camera aspheric mirror. A 200 mm diameter aspheric mirror was fabricated by SPDTM. Aluminum alloy as mirror substrates is known to be easily machined, but not polishable due to its ductility. Aspheric large reflector without a polishing process, the surface roughness of 5 nm Ra, and the form error of
