Description :

The NS shutter series are an array of patented devices that are actuated by a non-contact actuator. Only two unique parts are required for operations of these devices, the blades and the associated drive ring. These devices are best needed in applications where speed and reliability are required. Current uses for the NS shutters have been within camera applications for slow motion control, global mapping and also used within video cameras.

The UNIBLITZ ® N-CAS® NS series are clear aperture (from 25mm to 65mm) bi-stable shutter requiring no power to hold the shutter in either the open or closed state. Power is only required to change the state of the device. The NS25B is 25mm clear aperture both Uni-stable and Bi-stable shutters systems.
