The Uniblitz DSS20B is a 20mm bi-stable optical shutter that features an extremely low-profile construction. The device’s lack of an external protruding actuator makes it very slim and flexible for system integration. The inherent reliability of the DSS20B comes from the fact that it contains only two moving parts: the drive ring and the blades. It is guaranteed to operate for 2,000,000 operations.

Bi-stable shutter devices, like the DSS20B, require no power to hold the blades in either the open or closed state.
