In order to accommodate applications where the X-ray flux is too high for both the detector and the electronics that process the X-ray spectrum, Amptek has developed a "Collimator Kit" to collimate the primary X-ray beam. This system is comprised of the standard XR100 1.5 in box which slides inside the EXVC Collimator Housing.
The EXVC Collimator Housing can accommodate up to two Tungsten (W) collimator disks that are placed inside a bayonet holder in front of the detector. By selecting the appropriate Tungsten collimator disks, the user can reduce the incoming X-ray flux and allow the detector and electronics to process the X-ray spectrum. Seven different Tungsten collimator disks are provided with different size holes in order to allow for a wide range of applications.
The EXVC Collimator Housing is made of stainless steel and can also be used inside a vacuum chamber.

All dimensions are in inches except as noted.

All Tungsten disks are made of alloy HD17 (90% W, 6% Ni, 4% Cu).
All Tungsten disks and spacers have a diameter of 0.625 inches.
Optional: EXVC-W-SPACER
This Tungsten (W) Spacer /Collimator is 36 mm thick with a 300 µm hole. It is designed to stop and collimate x-rays greater than 100 keV produced from high energy tubes.
