VS14 14mm Uni-stable Shutters

OVERVIEW
The UNIBLITZ® VS14 and VS25 shutter series have been designed to give accurate, repeatable exposures for a wide
variety of applications. They have been successfully field tested in microscopy. video imaging. PMT protection, and
photographic applications worldwide.
Available with either 14mm or 25mm apertures, these shutters are offered in either cased or uncased configurations.
The uncased shutter allows a high degree of flexibility when mounting the unit in situations inaccessible to most
shutters due to spatial limitations. The cased version of this series is very popular due to the protection the black
anodized aluminum housing provides the precision shutter mechanism.
To further enhance the adaptability of this series, we offer several customized mounts and mounting systems for
popular microscopes and video imaging applications.
Further enhancement to the shutter is when it is used with laser or high energy non-coherent light sources. Alternate
reflective blade coatings and finishes are available. 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.
For those applications where the shutter will be used to switch a mercury arc lamp, we strongly recommend the "R1"
modification. This modification will allow the shutter to operate under the intense heat produced by mercury lamps.
Additional information can be found in the specific sheet entitled "MOUNTING SYSTEMS".
