Uni-Stable Shutters, Aperture 25mm
Manufacturer's part number :
The UNIBLITZ®VS25 shutter series has been designed to give accurate, repeatable exposures for a wide variety of applications. They have been successfully field tested worldwide in microscopy, video imaging, PMT protection, and photographic applications.
The VS25 shutter is offered in either cased or uncased configurations. The uncased shutter allows a high degree of flexibility when mounting the unit in applications where spatial limitations are a concern. The cased version offers the protection of a black anodized aluminum housing.
The VS25 incorporates our unique, constant force linear actuator and can be driven with our existing drive units. Recommended drivers are listed above. These include bench top and OEM types depending on your application.
Alternate blade coatings and finishes are available. To accommodate laser energy ratings up to 10W/mm2 with "Z" or "ZM" shutter blade coating options. Two standard reflective blade options are available, "Z" (AlSiO) and "ZM" (AlMgF2).
For information on typical laser damage thresholds see the Optical Shutter Comparison Chart. For further information see our Laser Application Reference Sheet.
For applications where the VS25 shutter will be used in a microscope, for example, to switch a mercury arc lamp, we strongly recommend the "R3" modification. This modification will allow the shutter to operate under the heat produced by mercury lamps. Learn more about the R3 High Temp Option.
To further enhance the flexibility of the VS25, we offer several customized mounts and mounting options for popular microscopes and video imaging applications please see mounting systems.
