KAPPA Goniometers

Multi-Axis Rotation for Uncompromised Precision and Enhanced Data Collection

Take your single-crystal X-ray diffraction experiments to the highest level with our unique four-circle goniometer technology.

Four-circle goniometers precisely orient both the crystal and detector for systematic access to the reciprocal space, delivering complete and redundant datasets and highly accurate intensity measurements. The result? Optimized data collection, even for challenging samples such as small crystals or those with strong absorption.

KAPPA Goniometer: Increase the Accuracy of Your Diffraction Experiments

In our KAPPA goniometers we use an all-rotational approach to single-crystal X-ray diffraction to achieve the highest in-house measurement accuracy and data quality. 

The unique KAPPA goniometer, invented by Bruker, is now the benchmark for advanced goniometry in single-crystal XRD. The goniometer's compact rotational mechanism minimizes mechanical obstructions and supports precise, reproducible positioning.

The greater orientational freedom provided by KAPPA goniometers keeps the sample accurately in the beam center at all orientations, delivering improved data quality and high redundancy datasets. The geometry easily enables orientated scans, inverse beam measurements and delivers the highly-redundant data required for, for example, challenging experiments on strongly absorbing samples.    

Why is KAPPA Geometry Superior?

KAPPA goniometers use rotational axes only to ensure the highest reproducible positioning. This compact, rotation-only geometry minimizes the sphere of confusion and increases long-term stability. 

< 7 µm Sphere of Confusion

Keeps even the smallest of crystals centered during multi-axis motion.

Four-Axis Flexibility

Enables tailored crystal orientations and advanced scan strategies.

High Precision Encoders

Ensure accurate and reproducible angular positioning.

Smart Motion: Intelligent Path Planning for High-Throughput Analysis

KAPPA Goniometers are protected by Smart Motion technology which ensures collision-free operation of the insutrment without, for example, crash plates and potential errors related to these.

Advanced path planning algorithms calculate efficient, collison-free trajectories and positional changes in the goniometer axes throughout the measurement process. Complex movements become automatic and predictable, with no user input required.

  • Higher throughput: Optimized measurement pathways make data collection faster.
  • Superior Instrument Protection: Advanced path planning eliminates the risk of collisions.
  • Simpler workflows: Automatic management of sophisticated multi-axis movement.
  • Runs automatically: Users can focus the data instead.

Built for Demanding Crystallography

While beneficial for every crystallography experiment, KAPPA goniometers particularly excel in demanding applications. Expanded orientational freedom and intelligent automation enable advanced data-collection strategies to tackle even the most challenging samples.
