Uniblitz® FS35
35mm Uni-Stable Optical Shutter

Overview

Key Features

The Uniblitz FS series shutters are designed and optimized to•35mm aperture

operate directly from +5VDC and do not require a separate driver.

•Default closed operation, +5VDC
opens the shutter, 0VDC closes

Removing the +5VDC (0VDC) closes these shutters. A simple control
circuit can be used to operate these shutter devices from a TTL
trigger pulse. This control can be also accomplished with our new
VLM1 TTL control interface (available soon).
