The UNIBLITZ® LS3 series is a 3mm clear aperture especially well
suited for laser use.
Designed for low level chopping, pulse gating, selection, and modulation to 200Hz.
Precision exposure control in the areas of holography and laser switching are additional applications that benefit from the precise, repeatablecharacteristics of the LS shutter series.
Three aperture sizes available: 2mm, 3mm, and 6mm.
Laser energy ratings up to 5W/mm2 with "Z" or "ZM" shutter blade coating options.
Exposure repetition rates from DC - 200Hz.
Electronic Synchronization System available.
Available in a normally-open configuration.
Available in an un-housed configuration through special order.

held in the open position.
The Electronic Synchronization System provides a feedback signal (through the driver utilized) after the shutter
transfers to the open state. The system incorporates aninfrared emitting diode, an infrared sensitive detecting
transistor, and an interrupting vane. The vane is attachedto the shutter so as to block the light path between theemitter and detector in the closed position. When theshutter transfers to the 80% open position, the vane isremoved from the infrared light path, allowing the emitterto switch the detector to the active state. No connection
to the designated synchronization pins when no electronic sync. is selected.
