- Requiring only standard power and a lab workbench, the X4 POSEIDON fits into any lab, bringing high-quality, non-destructive 3D imaging to everyone, everywhere!
A Modular, Desktop System that is Built to Evolve
The X4 POSEIDON is a modular X-ray tabletop microscope. The instrument can be upgraded according to changing needs and, as the technology evolves, new components can be easily integrated.
The X4 POSEIDON is a comprehensive micro-CT solution from the start featuring many premium features to enhance the user experience.
In its essential configuration the X4 POSEIDON includes a proven reflection X-ray source and versatile flat panel detector. With these components, the system is capable of ultra-fast scanning with exceptional field-of-view and razor-sharp contrast without compromising resolution.
Whether your lab supports multiple users in diverse research and development fields or a specific industrial process, the X4 POSEIDON offers the full power of nondestructive, qualitative and quantitative 3D analysis.

GEM Plus™: Ultimate Flexibility in Imaging
By combining Best-Scan-Geometry and Multi-Vision, the X4 POSEIDON delivers ultimate flexibility in a benchtop with Geometric Magnification Plus - GEM Plus™.
A balance of field-of-view and resolution is achieved by moving the sample closer to the source or closer to the detector. With Best-Scan-Geometry, the detector can also be moved in a continuous way, allowing ideal cone beam utilization for a given sample size while achieving the same magnification ratio, resulting in a significant scan speed improvement.
GEM Plus™ builds on Multi-Vision and Best-Scan-Geometry to strike the perfect balance between pure resolution, scan speed and field-of-view.

Multi-Vision: Dual-Detector Technology for Fast and High-Resolution 3D Imaging
The X4 POSEIDON is the only true multi-detector benchtop XRM solution. It can be equipped with a versatile flat-panel detector, a scientific-grade CMOS detector, or both!
When selecting the ideal detector for your needs, you must consider the balance between field-of-view, resolution and scan speed. If speed is of upmost importance, the flat-panel detector is ideally suited for your application. On the other hand, the sCMOS detector is the ideal choice for maximum resolution.
With the X4 POSEIDON you don't have to choose - Thanks to Multi-Vision you can have both!
The X4 POSEIDON platform allows for the on-site upgrade to Multi-Vision.

Brilliant X-Ray Power
The X4 POSEIDON supports the latest generation of microfocus X-ray sources. The platform allows on-site source exchange as your needs evolve over time.
High Energy Reflection X-Ray Source
The reflection X-ray source produces an X-ray beam with energy up to 100 kV and 20 W power. This industry-grade source is the perfect choice for your workhorse solution in a multi-user facility, service lab or screening environment. It requires no maintenance and features a low cost of ownership.
Microfocused Transmission X-Ray Source
The transmission X-ray source achieves a 2 µm spot size and is the perfect research solution to obtain high resolution data. A maximum energy of 110 kV extends the application range to higher density and larger samples.
Our 3D Resolution Guarantee
Every Bruker 3D X-ray Microscope comes with the unique 3D resolution guarantee. The 2D and 3D resolution performance is tested and documented with industry standard JIMA 2D and 3D QRM phantoms during factory calibration. After installation, on-site performance is guaranteed by repeating the 2D JIMA measurement.


Increase Productivity and Throughput
The X4 POSEIDON can be upgraded with a 15-position sample changer to maximize instrument usage and minimize operator interaction.
The compact sample changer is ergonomically positioned in front of the instrument. The status of each position is indicated by an LED allowing sample addition or replacement at any time, even during operation. The intelligent loading algorithm (patent pending) optimizes sample throughput.
Each position accommodates samples up to 50 mm diameter and 80 mm height. Small samples can be stacked vertically and bundled to increase capacity.
When not in use, the sample changer can stay installed while having full access to the instrument for loading large samples or specialty stages.

4D-CT: Flawlessly Integrated
Enhanced throughput by source power, detector speed efficiency, variable geometry and advanced scanning modes opens new possibilities for in situ 4D-CT experiments using proprietary specialty stages for compression testing, tensile testing and testing at non-ambient temperatures.
The Bruker material testing stages can perform compression and tensile experiments up to 4400 N and 440 N, respectively, while Bruker's heating and cooling stages can reach temperatures of 25 °C below ambient to 80 °C.
All stages are integrated into the software and hardware eliminating the need for cables. A cable feedthrough in the enclosure allows use of custom or third-party stages.

3D X-Ray Imaging for any Application: See What Lies Beneath

No analytical technique is as commonplace as microscopy because seeing is believing. Whether using visible light, electrons or atomically sharp cantilevers, these probes are limited to the surface.
X-ray Microscopy is a shift in paradigm, providing a nondestructive three-dimensional view into the microscopic world; giving insight into internal structure and shedding light on the mechanism of failure or confirming successful fabrication.
3D X-ray imaging adds the third dimension to microscopy.
