In the optical component supporting structure and the optical component supporting structure which has with the production

摘要

The optical element retainer (29), the lens (28) the periodic damping board of the annular condition which covers the peripheral side part (41) with, the connected component which consists of the damping alloy which in state of non contact is locked on the framework body the lens (28) vis-a-vis the surface (42) with it has that periodic damping board. The squeeze film damper is formed the periodic damping board (41) with, that periodic damping board and the lens (28) due to with the nitrogen gas which exists inside opening C where it was formed with the surface.
