Current Lead Time: 6 – 7 weeks
Current Lead Time: 6 – 7 weeks
The Uniblitz XRS25 has been designed specifically for x-ray switching applications. The innovative platinum-iridium (PtIr) blade design allows beam extinction of 90% up to 30 keV x-ray energy (based upon the tenth value extinction of PtIr). The XRS25 is well suited for applications such as x-ray crystallography, medical x-ray imaging, etc.
Uni-stable shutter devices, like the XRS25, require power to hold the blades in the open state. Note: This device requires two drive channels. The indicated driver will determine the included cable (910C-D7 or 910C-D5).
As of May 1, 2019, the 7-pin Female Mating connector is no longer included with purchase. Purchase 7-pin Female Mating Connector.

Electronic Synchronization System
[columns] [span7]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. For the XRS25, this system uses a similar activation flag attached to the mechanism, which triggers a reflective emitter/detector device. 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.
