Uniblitz® NS65B
65mm Bi-Stable Optical Shutter

Overview

Key Features

The Uniblitz NS65B is a 65mm-aperture bi-stable optical shutter••

65mm aperture

utilizing our patented N-CAS® technology. The NS65B’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 telescopes, video••

Slim, low-profile form-factor

cameras, etc. The NS65B has an overall diameter of 5.15 inches, and••RoHS Compliant

an electronic synchronization is available.

••

Transfer time on opening:
33.0 milliseconds

Bi-stable shutter devices, like the NS65B, require no power to holdthe blades in either the open or closed state.
