Uniblitz® VS2525mm Uni-Stable Optical Shutter

Overview

Key Features

The Uniblitz VS25 has been designed to provide accurate, repeatable••

25mm aperture

exposures for a wide variety of applications. The VS series shutters••

Uni-stable operation

have been successfully field tested in microscopy, video imaging,••Slim, small form-factor

PMT protection, and photographic applications worldwide. The••

RoHS Compliant

VS25 is available in a housed or un-housed configuration for OEM••

applications (or simply where spatial limitations are a consideration).
••Uni-stable shutter devices, like the VS25, require power to hold theblades in the open state.

incorporates an infrared emitting diode, an infrared sensitive detecting
transistor, and an interrupting vane. The vane is attached to the shutter soas to block the light path between the emitter and detector in the closedposition. When the shutter transfers to the 80% open position, the vaneis removed from the infrared light path, allowing the emitter to switch theGND
