LS2 2mm Uni-stable Shutters

OVERVIEW
The UNIBLITZ®LS series shutters are especially well suited for laser use, with applications including low level
chopping, pulse gating, selection, and modulation to 400Hz. Precision exposure control in the areas of holography and
photography are additional application that benefit from the precise, repeatable characteristics of the LS shutter series.
For information on typical laser damage thresholds see "OPTICAL" information in our "COMPARISON
SPECIFICATION" sheet. For further information see our application note "LASER APPLICATION REFERENCE" sheet
in the resource section of our web site, www.uniblitz.com.
The LS shutter series is comprised of three models. The model LS2 features a 2mm aperture, with typical rise time of
300µsec. The LS3 and LS6 models feature a 3mm and 6mm aperture, respectively. All three styles are offered
mounted in a black anodized aluminum housing, and are equipped with the electronic synchronization system. In
addition to the standard housing illustrated on the opposite side, several customized microscope and video mounts are
available as options for use with this series. Additional information can be found in the sheet entitled "MOUNTING
SYSTEMS."
