Abstract

본 발명은 광디스크 드라이브의 픽엎(Pick-Up)광학계를 조립시 광축의 편이를 검사 및 측정하는 오토콜리메이터(Autocollimator)에 관한 것으로, 자동 오토콜리메이터의 기준 레티클을 대물렌즈의 촛점위치와 화이트 램프(White Lamp)의 발광을 접속하는 위치와 상호 일치하는 곳에 하나의 레티클을 설치함으로써, 램프 발광빛이 레티클에서 일부 반사되어 온 상을 기준 레티클로 설정하여 동작시 시각적으로 항상 기준 레티클이 시야에 있음을 알 수 있도록 하고, 일부 투과되는 광은 피사체(평면 거울등)에서 다시 반사되어 레티클에 맺는 상을 비교하여 상호 벗어남을 측정 및 검사하도록 하고 있다.The present invention relates to an autocollimator for inspecting and measuring the deviation of an optical axis when assembling a pick-up optical system of an optical disc drive. By installing one reticle at the same position as the position where the light emission of lamp is connected, it sets the image where the lamp light is partially reflected from the reticle as the reference reticle. Some transmitted light is reflected back from the subject (plane mirror, etc.) and compared to the image on the reticle to measure and inspect the mutual deviation.
