Zusammenfassung: | According to an embodiment of the present invention, a total pitch measuring apparatus of an optical film is applied to a passive type display, has an L pattern and an R pattern which have different optical axis, and comprises: a stage on which an optical film is mounted; a photographing unit photographing total pitch of the optical film mounted on the stage, and mounted on the stage to be moved in a vertical direction of the L pattern and the R pattern of the optical film; and a filter unit arranged between the stage and the photographing unit, having at least two filters having a predetermined polarizing axis. According to the present invention, provided is the total pitch measuring apparatus of an optical film, which can reduce measurement errors when measuring a total pitch of an optical film.
본 발명의 일 실시예에 따른 패시브 방식의 디스플레이에 적용되며 서로 다른 광축을 갖는 L 패턴과 R 패턴을 구비하는 광학 필름의 총 피치 측정장치는, 광학 필름이 안착되는 스테이지, 스테이지에 안착된 광학 필름의 총 피치를 촬영하며, 광학 필름의 L 패턴과 R 패턴의 수직 방향으로 이동 가능하게 스테이지에 장착되는 촬영 유닛 및 스테이지와 촬영 유닛 사이에 배치되며, 소정의 편광축을 갖는 적어도 둘 이상의 필터를 구비하는 필터 유닛을 포함하는 것을 특징으로 한다. |
