Light control apparatus and optical apparatus
摘要:
There is provided a light control apparatus that maintains the overall apparatus size small, increases the number of stop stages, and is suitable for both the shutter and stop actions. A light control apparatus includes a first actuator, a second actuator, a first light shielding member driven by the first actuator, and a second light shielding member driven by the second actuator, wherein in a stop adjusting action, the first and second actuators drive the first and second light shielding members and adjust an aperture formed by the first and second light shielding members, and wherein in a shutter action, the second actuator drives the second light-shielding member for a light shielding action.
