Slit Systems
Over the last 25 years, JJ X-Ray has designed a large portfolio of slit systems used at x-ray and neutron facilities all over the world. Our top priority is to give the customer the best solution whether they need the slit system to be standard, modified or customized.

Collimators
All collimators are based on a custom design and are divided into three categories defined by the orientation of the foils.

Optics
JJ X-Ray A/S supplies high-precision refractive and reflective optics for synchrotron applications. Their refractive optics include SCD CRLs and lenses in beryllium, aluminum, and nickel for beam focusing. Reflective optics feature customizable mirror systems suitable for UHV/XHV environments, offering options like bending, cooling, and heating for enhanced stability and performance.

Monochromators
JJ X-Ray A/S provides a range of monochromators designed for precise control of X-ray wavelengths in various research and industrial applications. Monochromators are essential for selecting specific wavelengths from an X-ray beam, improving the quality and resolution of diffraction and spectroscopy measurements.

Diagnostics and Analysis
JJ X-Ray offers a range of cutting-edge products designed to enhance the precision and reliability of X-ray analysis systems. Diagnostic and analytic tools are essential for accurately measuring and analyzing X-ray beams, ensuring optimal performance across a variety of applications.

Positioning Systems
JJ X-Ray offers an extensive selection of positioning systems, designed for exact motion and endurance with a focus on scientific sector. Achieving groundbreaking results hinges on precise control, and our systems deliver reliable, repeatable motions for a variety of applications.

Custom Solutions
When working on complex or custom projects, we always work in close collaboration with the customer to make sure all requirements are met, and projects are executed in a timely manner.

Custom Air Slit
Sometimes, limited space around the beamlines or special requirements for aperture size makes it difficult for a standard size slit to fit into specific instrumentation. In that case, we can design and produce a customized solution which is developed from our standard slit systems – but with a rectangular housing.
Just as the classic IB-slit, the aperture is defined by four independently movable blades (2 blades for DEMI slit systems). The blades are, in turn, controlled by a high-precision guiding rail system and high-resolution stepping motors. In general, specifications and options often are very similar to our standard IB-slits.
The customer defines blade shape and material. If the slit system is for an x-ray facility, the typical blades are 2, 5, or 10 mm tungsten carbide blades – e.g., with 0.5 degrees knife-edge, R16 cylindrical edge or 90-degree rectangular edge. For neutron instrumentation, we usually use Boron Carbide.
If it is not possible to use a standard square system in your instrumentation (the most cost-effective solution), you can also check our already existing designs of rectangular slits systems here. Please contact us for more information on a particular slit system.
In our slit catalog, you can have a quick overview of the large variety of JJ slit systems.
