Abstract
An optical adjusting device includes: a rotating unit that includes and rotates about a through-hole through which light passes; at least one moving unit that is movably disposed relative to the rotating unit and is linearly movable between an advance position corresponding to the through-hole and a retreat position outside the through-hole; a transmitting unit that is disposed between the rotating unit and the moving unit and transmits a rotational force of the rotating unit to the moving unit; and an optical unit that is disposed on the moving unit and blocks at least part of light passing through the through-hole.
