VS35 35mm Uni-stable Shutters

OVERVIEW
The UNIBLITZ® VS35 shutter series electro-programmable shutter is one of the largest aperture shutters currently
offered in the UNIBLITZ® line. Like its smaller counterpart, VS25 series, the VS35 series shutters are offered in both
an uncased version and a black anodized aluminum housing. The uncased version allows a great deal of flexibility for
mounting the shutter in a limited area. This is especially important when design space is at a premium. The cased
version is very popular due to its rugged design and the protection it offers the shutter mechanism in systems where
the shutter is mounted in an exposed environment. The VS35 series has proven to be well suited to video applications
where a larger aperture is required. Further enhancement of the VS35 cased version can be achieved utilizing one of
the custom mounting systems available.
When the shutter is used in applications switching laser or high energy non-coherent light sources. Alternate reflective
blade coating 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"
enhancement. This modification will allow the shutter to operate under the intense heat produced by mercury lamps.
For additional information, please review the information found in "MOUNTING SYSTEMS".
