Uniblitz® LS3
3mm Uni-Stable Laser Shutter

Overview

Key Features

The Uniblitz LS3 is a high-performance laser shutter, ideal for•

3mm aperture, Uni-Stable

precision exposure control, laser switching, and other applications•

Laser Energy Rating:
5 W/mm2 (with "ZM" blades)that benefit from the precise, repeatable characteristics of the LS
shutter series. These include low level laser chopping, and pulse•

RoHS Compliant

gating, selection, and modulation to 200Hz.

•Transfer time on opening:
0.5 milliseconds

Uni-stable shutter devices, like the LS3, require power to holdthe blades in the open state (though the device can be customconfigured for "normally open" operation).
