OVERVIEW
One of the newest shutters in Vincent's UNIBLITZ® line, the XRS6 series is especially designed for x-ray applications. The innovative blade design allows beam extinction >104 up to 30Kev x-ray energy. The XRS6 shutter is well suited for specific x-ray applications such as x-ray crystallography and can gate within 3ms. ata maximum rate of 50 exposures per second. Precision control and reliability can be expected as with all UNIBLITZ® products.
This 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 XRS6 has a 6mm clear aperture and is equipped with the solid state synchronization system. Additional aperture sizes and vacuum compatibility may be available, please consult customer service for further information.
FEATURES
- 6mm diameter aperture.

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 NOCIRCUMSTANCES SHOULD ANY TYPE OF LUBRICANT BE APPLIED TO THE SHUTTER
BLADE AREA.
Unhoused Style
The XRS6 uncased style is the basic configuration of this series and is best suited for OEM applications. Mounting can be accomplished through one 2.5mm slot and one 2.5mm hole below the aperture. The unit terminates to a 7-pin male in-line connector through a six-inch cable assembly.
Housed Style
The XRS6#2 housing style allows a number of mounting configurations. A ¼-20threaded hole is provided for post mounting. The 1.625 inch x 40TPIexternal thread located on the rear side, and the six 2-56 threadedholes located on the front side (see Figure #2 and Figure #3) can beinterfaced directly into your application or fitted with a variety ofspecific mounting options. See “MICROSCOPE, VIDEO and UNIVERSALMOUNTING SYSTEMS” data sheets for additional information. The unitterminates with a 7-pin male connector.
