ABSTRACT:
A small size and lightweight light beam scanning device for scanning a laser beam to perform an operation under an operating microscope. A movable mirror is provided which occupies only a small central portion of the objective lens of the microscope. Horizontal rotary shafts are provided on an annular pivot frame outside the field of vision of the objective lens. Rotational movement around the horizontal axis is transmitted vertically downwardly from the center of the movable mirror by a lever mechanism. A vertical bearing mechanism permits the movable mirror to turn around the vertical axis together with the lever mechanism. Rotational movement around the vertical and horizontal axes is transmitted through a universal joint to a gimbal system operating lever by a single lever.
