Title:
LIGHT ADJUSTMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/175904
Kind Code:
A1
Abstract:
Provided is a light adjustment device capable of suppressing an increase in the size of the entire device even if the movable region of a diaphragm blade increases.
A light adjustment device comprises: a first substrate (101) and a second substrate (121) in which optical apertures (102, 122) are formed, respectively; at least one light adjustment means (130); a spacer (141) which is disposed between the first substrate and the second substrate and forms a space in which the light adjustment means is operable; and a drive means (132, 150) which operates the light adjustment means disposed on the first substrate, and by operating the light adjustment means by the drive means, rotates the light adjustment means between a first stationary position withdrawing from the optical aperture and a second stationary position overlapping with the optical aperture to adjust incident light passing through the optical aperture. The light adjustment means is protrudable outward from the first substrate and the second substrate when being in the first stationary position.
