X-Ray Soller

The soller collimator is a collimator with parallel, rectangular foils. The small x-ray soller version is typically used to limit radiation in x-ray diffractometers, either in highly customized laboratory settings or in synchrotron facilities.

The collimators are based on the JJ X-Ray standard gadolinium oxide coated stretch-foil technique.

For further details, please see examples in our collimator catalog.
