Abstract
A shutter assembly including first and second flexible layers and first and second coupling rings. Both the first and second flexible layers have a plurality of slits. When the shutter assembly is in a closed position, the first and second flexible layers are substantially planar, the second flexible layer is located adjacent to the first flexible layer, a longitudinal axis perpendicularly passes through the first flexible layer, the first flexible layer's slits meet at a first location, and the second flexible layer's slits meet at a second location, laterally spaced from the first location. Both the first and second flexible layers are located between the first and second coupling rings, which support the flexible layers with a sealed space located behind the flexible layers. Both the first and second flexible layers form a seal with a optical device when the shutter assembly is in an open position.
