OVERVIEW
The UNIBLITZ® XRS14 shutter series is especially designed for x-ray applications. The blade design allows beam extinction >104 up to 30Kev x-ray energy. The XRS14 shutter is well suited for specific x-ray applications such as x-ray crystallography and can open within 20.0msec at a maximum rate of 10Hz. Precision control and reliability can be expected as with all UNIBLITZ® shutter products.
The shutter is programmable, and is activated by an electronic pulse generated by Vincent's patented UNIBLITZ® drive systems. The shutter will follow this pulse, which allows the user to program the exposure duration and frequency.
The XRS14 has a 14mm clear aperture and can be equipped with the solid state synchronization system. Vacuum compatibility is also available, please consult customer service for further information.

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.
Unhoused Style
The XRS14 uncased style is the basic configuration of this series and is best suited for OEM applications. Mounting can be accomplished through seven 2.5mm holes around the unit’s outer perimeter. The unit terminates to a 7-pin male in-line connector through a six-inch cable assembly.
Housed Style
The XRS14 #2 case style allows a number of mounting configruations. A ¼-20 threaded hole is provided for post mounting. The 1.625in x 40TPI external thread, rear side, and the three 2-56 threaded holes, front side, can be interfaced directly into your applications or fitted with variety of specific mounting options. See “MICROSCOPE, VIDEO and UNIVERSAL MOUNTING SYSTEMS” data sheets for additional information. The unit terminates with a 7-pin male connector.
