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".

The question regarding enhancement of shutter speed with the application of user supplied lubricants has been repeatedly asked. It is our experience that lubricating the shutter blades will actually slow the shutter down and eventually render the shutter inoperable. UNDER NO CIRCUMSTANCES SHOULD ANY TYPE OF LUBRICANT BE APPLIED TO THE SHUTTER
BLADE AREA
Unhoused Style
The VS35 uncased style is the basic configuration of this series and is best suited for OEM applications. Mounting can be accomplished through seven 2.5mm holes around the unit’s outer perimeter. The unit terminates to a 7-pin male in-line connector through a six-inch cable assembly.
Housed Style
The VS35 #2 case style allows a number of mounting configurations. A 1/4-20 threaded hole is provided for post mounting. The 1.625in x 40TPI external thread, rear side, the three 2-56 threaded holes and the three 4-40 threaded holes, front side (Figure 3), can be interfaced directly into your application or fitted with a variety of specific mounting options. See "MICROSCOPE & VIDEO MOUNTING SYSTEMS" data sheets for additional information. The unit terminates with a 7-pin male connector.
