| Zusammenfassung: | The present invention relates to an automatic optical focusing apparatus and an optical apparatus including the same, wherein two light receiving units for focusing which are spaced the same distance from a focal point in opposite directions are varied according to a magnification of an objective lens. The automatic optical focusing apparatus easily adjusts a distance between a first light receiving unit and a second light receiving unit of a distance-adjusted light receiving unit from the focal point even when a focusing range increases or decreases by increase or decrease of the magnification of the objective lens. Therefore, precision and resolution of the optical apparatus can be improved while a structure is simplified.
본 발명은 초점 위치로부터 서로 반대방향으로 동일 거리 이격된 2개의 초점 조절용 수광부가 대물렌즈의 배율에 따라 가변되는 자동 광 초점 조절장치 및 이를 포함하는 광학장치에 관한 것으로, 본 발명의 자동 광 초점 조절장치는 대물렌즈의 배율이 증감하여 초점 맞춤 범위가 감소 또는 증가해도 초점 위치로부터 위치조절 수광부의 제1 수광부와 제2 수광부까지의 거리를 용이하게 조절할 수 있어서, 구조를 단순하게 하면서도 광학장치의 정밀도와 분해능을 높일 수 있다. |
