PF4 X-Ray Filter

The PF4 X-Ray Filter provides a flexible solution which can be used in a variety of applications. Four O-ring sealed, individually driven pneumatic cylinders allow the remote controlled insertion of filter foils or absorber blades, depending upon need.


The PF4 X-Ray Filter has applications in a variety of areas. This includes surface reflection studies, matching sample scattering strength to a detectors linear range, the adjustment of x-ray exposure in experiments requiring a particular x-ray dose or acting as a beam stopper to minimise sample damage.

The filter unit can be evacuated or He filled according to the scientists’ experimental requirement.

Flange adapter kits are also available, thus enhancing the adaptability of the product.
