Abstract: A movable sunshade system includes a baffle extending along a central axis of an entrance pupil of a lens and a sunshade movably connected to the baffle. The sunshade includes a first portion shaped to cover a portion of the baffle that is spaced from the first end of the baffle and a second portion that extends from the first portion. The second portion is shaped to cover a portion of a field of view (FOV) of the entrance pupil. The movable sunshade system further includes an actuator configured to move at least one of the baffle or the sunshade to selectively cover portions of the FOV of the entrance pupil.
