Uniblitz® NS35B
35mm Bi-Stable Optical Shutter

Overview

Key Features

The Uniblitz NS35B is a 35mm-aperture bi-stable optical shutter••

35mm aperture

utilizing our patented N-CAS® technology. The NS35B’s simple design••

Bi-stable operation

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

Only two unique moving parts

flat surface makes for its easy integration into virtually any system.

••RoHS Compliant

The NS35B has an overall diameter of 3.18 inches, and an electronic••

Transfer time on opening:12.0 milliseconds

synchronization is available.
••

Bi-stable shutter devices, like the NS35B, require no power to holdthe blades in either the open or closed state.

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