Abstract
A system includes a plurality of optical elements, a deformation unit configured to deform a deformable optical element satisfying a following conditional formula included in the plurality of optical elements by applying a force to the deformable optical element:0.75<0<0.95where EA0 represents an effective aperture of each of the plurality of optical elements and EA represents an axial light flux diameter of each of the plurality of optical elements, and a control unit configured to control the deformation unit, wherein n positions on an outer circumference of the deformable optical element are fixed, the deformation unit includes n actuators, the n actuators apply forces to n positions on the outer circumference other than the fixed n positions, and the control unit controls each of the n actuators independently.
