XRD Optics

X-rays generated by the source are shaped by optics into a useful X-ray beam, optimized for the size and shape of the sample and the application. Bruker AXS’ comprehensive portfolio includes single-crystal type optics such as Johansson and channel-cut monochromators, polycapillary lenses, and in particular multi-layer optics.
Alignment- and tool-free optics change


DAVINCI.SNAP-LOCK is our unique, high-precision mechanism, which enables all the optics to be exchanged within just a few seconds, without tools and without requiring adjustment. All optics return to perfect alignment every time. In addition, the DAVINCI.MODE registers every optics on the system with its specific characteristics and configures it automatically. Each component, replacement and status change is instantly recognized and visualized on the virtual goniometer of the DIFFRAC.DAVINCI software plugin, which also reports any configuration conflicts.
Changing configurations has never been so easy, fast and reliable.

For ultimate ease-of-use we have gone even a step further and developed the TWIN/TWIN, TRIO and PATHFINDER optics, all incorporating multiple beam path modules available at the touch of a button.  

Push-button switch of instrument geometries


With the pioneering TWIN/TWIN design switching between four different instrument geometries is done with the push of a button, reliably and without user intervention. Experience effortless change from classic powder diffraction applications to amorphous and polycrystalline thin-film analysis.

  • The primary TWIN optic features a motorized divergence slit for Bragg-Brentano geometry and a Göbel mirror for the parallel beam geometry.
  • The secondary TWIN optic implements both the appropriate motorized anti-scatter slit for Bragg-Brentano, and an equatorial Soller slit for parallel beam geometry.


Maximum flexibility meets unparalleled ease-of-use


The patented TRIO optics uniquely enables pushbutton, automated switching between up to six different beam geometries when combined with the secondary TWIN optics. Switch between the three most commonly used primary beam geometries without user intervention:

  • Motorized slits for a focused beam geometry used for conventional Bragg-Brentano powder diffraction
  • Göbel Mirror for high intensity Cu-Kα parallel beam for capillary experiments, height insensitive measurements, surface sensitive grazing incidence geometry, coating thickness determination and micro-diffraction
  • Göbel Mirror + 2-Bounce Ge Channelcut monochromator for highly parallel Cu-Kα1 beam for high-resolution diffraction (HRXRD) of epitaxial thin films and pure Kα1 diffraction patterns of powder samples


The PATHFINDERPlus optics allows switching between double-axis and triple-axis geometries with a simple mouse-click. Designed with an extra large aperture, the PATHFINDERPlus optics uses the entire field of view of the LYNXEYE detector family. The PATHFINDERPlus optics offers unprecedented flexibility and seamless measurements - including fully automated sample alignment – over the full range of samples in thin film analysis and research:

  • Motorized slit for high flux measurements: XRR and HRXRD investigations on samples with low mosaicity or samples with strongly tilted layers.
  • 2-bounce analyzer crystal for applications that require high resolution and low background, like XRR, HRXRD and RSM investigations.

In addition, the PATHFINDERPlus includes an automated absorber to ensure linearity of the measured intensities.  

Perfect Powder Data - Automatically

Dynamic Beam Optimization™ (DBO)

Bruker's unique Dynamic Beam Optimization (DBO) feature sets a significant new benchmark in terms of data quality for X-ray diffraction. The automatic synchronization of motorized divergence slits, a motorized anti-scatter screen, and the variable field-of-view active detector window provides unparalleled data quality, specifically at low angles 2Ɵ. DBO is supported by all members of the LYNXEYE detector family: SSD160-2, LYNXEYE-2, and LYNXEYE XE-T, and also by the EIGER2 R 500K detector.
