- the light pressure rotator 1 is formed by rotating the central axis of the light by the light condensed and irradiated from above. Because it rotates light pressure around o, it can be driven remotely. In addition, since the light pressure is rotated in a state where the light pressure is trapped in the vicinity of the focal point of the focused light, no bearing is required, and only the position of the objective lens 9 is moved, so that the light pressure rotator 1 can be moved to an arbitrary position.
