摘要:
An optical element holding apparatus includes an annular vibration attenuation plate, which covers a peripheral portion of a lens, and a connection member, which is formed of a damping alloy and which fixes the vibration attenuation plate to a frame body in a state of non-contact with the surface of the lens. The vibration attenuation plate and nitrogen gas in a clearance between the vibration attenuation plate and the surface of the lens form a squeeze film damper.
