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.

AT-F7-HV
The AT-F7-HV slit is an enhanced version of the original ESRF slit (AT-F7-AIR), which was designed for application in air or inside a larger vacuum chamber. We extended the ESRF design to also allow for connectors via vacuum flanges.
The characteristics of this system are the same as for the AT-F7-AIR slit: The compact size, the blade control (where one motor defines the aperture size and another determines the position of the aperture) and the sub-micron resolution. The slit is operated with in-vacuum motors.
A distinctive feature of the AT-F7-HV and AT-F7-AIR slit systems are the flexible positioning of their 7 mm x 7 mm aperture due to a total translation travel range of 14 mm.
