Uniblitz® NS25B
25mm Bi-Stable Optical Shutter

Overview

Key Features

The Uniblitz NS25B is a 25mm-aperture bi-stable optical shutter••

25mm aperture

utilizing our patented N-CAS® technology. The NS25B’s simple••

Bi-stable operation

design provides maximum clearance around the aperture, and a••

Only two unique moving parts

machined flat surface makes for its easy integration into virtually any••

RoHS Compliantsystem. The NS25B has an overall diameter of 2.250 inches, and an••Transfer time on opening:
5.0 milliseconds

electronic synchronization is available.
••

Bi-stable shutter devices, like the NS25B, require no power to holdthe blades in either the open or closed state.

Total opening time:
8.0 milliseconds••Can be configured for theVED24, VDM1000, or ED12DSS
shutter drivers.
