More Information
Summary:According to the present invention, an alignment system for a freeform optical system includes: an incident optical system where a laser forms a beam path to be incident on a freeform optical system; a focusing monitoring device for focusing and monitoring a laser reflected by the freeform optical system; and an optical system alignment stage which fixes and supports the freeform optical system and translates or rotates the freeform optical system based on the shape of an image outputted from the focusing monitoring device and aligns the freedom optical system. It is possible to increase alignment accuracy and greatly reduce alignment time. 본 발명에 따른 자유형상 광학계 정렬 시스템은 레이저가 자유형상 광학계로 입사되는 빔 경로를 형성하는 입사 광학계; 상기 자유형상 광학계에서 반사되는 레이저를 집속시켜 모니터링하는 집속 모니터링 장치; 상기 자유형상 광학계를 고정 지지하며, 상기 집속 모니터링 장치에서 출력되는 이미지의 형상을 기초로 상기 자유형상 광학계를 병진 또는 회전 이동시켜 정렬하는 광학계 정렬 스테이지;를 포함한다.
