Uniblitz® DSS25B
25mm Bi-Stable Optical Shutter

Overview

Key Features

The Uniblitz DSS25B is a 25mm-aperture bi-stable optical shutter•

25mm aperturethat has eliminated the external protruding actuator and contains no•

Bi-stable operation

other interfering components. This makes the DSS25B an extremely•

Only two unique moving parts

low-profile device that is capable of fitting into very tight spaces.

•Slim, low-profile form-factor

Additionally, the device's flat mounting surfaces make for its easy•

RoHS Compliant

integration into virtually any system.

•Transfer time on opening:
12.6 milliseconds

Bi-stable shutter devices, like the DSS25B, require no power to holdthe blades in either the open or closed state.
