Collimators for X-Ray Techniques
Press Release
23.11.2011
piezosystem jena is pleased to announce a new piezo based collimator system for
X-Ray techniques.
Current techniques in X-Ray microscopy, crystallography and small angle x-ray scattering require extremely well-collimated beams.
In order to achieve the best signal to noise ratio in an x-ray system, the aperture size should be as closely matched as possible
to the sample size.
Most X-ray systems use a pinhole aperture that has been drilled or laser ablated from a tungsten or tantalum disk of material.
In practice this means that for every new sample size, the pinhole should be removed and a new size inserted.
A solution was developed in cooperation with Lawrence Berkeley National Lab.
Based on two piezo driven slit systems of the series
PZS 4 (part number: O-101-xx),
a collimator for X-Ray techniques was made. The PZS stages are mounted of 90° in respect to each other.
Because of the high resolution piezo element, the slit edges can be adjusted precisely to the required size.
With a resolution of <8 nm the system is the most accurate variable aperture system commercially available.
The open architecture of the PZS slit system design allows for easy integration into a variety of X-Ray systems.
A V-clamp holder allows
the customer to add his own or our accessories. The entire system can be made vacuum compatible.
