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.
