Certain configurations of this device are available on Amazon:
The UNIBLITZ® LS6 series shutters are designed for high speed operation and are well suited for laser use. The LS6 features a 6mm aperture and a typical rise time of 700µsec.Applications include fiber optic switching, low level chopping, pulse gating, selection, and modulation to 150Hz. In addition, the LS6 is well-suited to precision exposure control in the areas of holography and laser switching, where the precise, repeatable characteristics of the shutter are a requirement.
The LS6 shutter is offered in either housed or un-housed configurations. The un-housed shutter allows a high degree of flexibility when mounting the unit into applications where spatial limitations are a concern. The housed version offers the installation of the shutter device in a small black anodized aluminum housing. This allows for use of available mounting options and protection of the shutter device within the application's environment.
The LS6 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 5W/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 Optical Shutter Comparison Chart . For further information please see our Laser Application Reference Sheet .
The LS6 can also be configured with the R3 high temperature option for high ambient environments.
To further enhance the flexibility of the LS6, we offer the Electronic Synchronization System. Also available are customized mounting systems and numerous standard mounting systems option for popular microscopes and video imaging applications.

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

The question regarding enhancement of shutter speed with the application of user supplied lubricants has been repeatedly asked. It is our experience that lubricating the shutter blades will actually slow the shutter down and eventually render the shutter inoperable. UNDER NO CIRCUMSTANCES SHOULD ANY TYPE OF LUBRICANT BE APPLIED TO THE SHUTTER BLADE AREA.

The LS #2 case style allows a number of mounting configurations. A 1/4-20 threaded hole is provided for post mounting. The 1.625 in. x 40 TPI external thread, rear side, and the six 2-65 threaded holes, front side, can be interfaced directly into your application or fitted with a variety of specific mounting options. For additional information about applicable mounting systems click here. The unit terminates with a 7-pin make connector. Drawings of the device in its normally open and un-housed configuration are available under the Download tab.
