Experts in advanced X-Ray microscopy

We use X-Ray microscopy to research biological structures, biomaterials and bio-inspired engineering materials


The Zeiss Global Centre (ZGC) is a collaboration between the School of Mechanical and Design Engineering at the University of Portsmouth and Carl Zeiss Ltd. It is an important part of the HEFCE-funded Future Technology Centre.

At the Zeiss Global Centre, we research the competence of biological structures, biomaterials, and bio-inspired engineering materials using advanced X-Ray microscopy.

We support the work of the Advanced Materials and Manufacturing Research Group at the University of Portsmouth, and also provide excellent training and consultancy opportunities for academic and industrial collaborators.

Research

Our work within the Zeiss Global Centre covers the following areas of expertise – find out more below.

Facilities

The Zeiss Global Centre is equipped with the latest x-ray imaging and in-situ mechanical testing technology, and high-performance computing facilities.

In addition to licensed software for accurate post-processing and analysis of images, the Zeiss Centre makes use of the following equipment and experiments.

Equipment and experiments

Versa 510 (Zeiss)

The Zeiss Xradia 510 Versa 3D X-ray microscope allows sub-micron resolution for samples from millimetres to centimetres, achievable via a unique RaaD (resolution at a distance) capability. The instruments powerful combination of world-leading resolution and contrast with flexible working distances provides outstanding non-destructive imaging performance.

Versa 520 (Zeiss)

The Zeiss Xradia 520 Versa 3D X-ray microscope unlocks new degrees of flexibility for scientific discovery and expands the boundaries of non-destructive imaging with innovative contrast and acquisition techniques. Xradia 520 Versa achieves a minimum voxel size of 70nm.

CT5000 (DEBEN)

The CT5000 5kN in-situ tensile stage for µXCT applications is a modular tensile and compression testing system with a maximum extension of 10mm and a 5kN load cell with an accuracy of 1% (of full-scale range). The actuator speed ranges 0.1mm/min to 1.0mm/min. The stage is equipped with an environmental chamber and Peltier heated and cooled jaws with temperature range from -20°C to +160°C. Size: 117mm diameter, 285mm to the bottom of the tube, tube length to suit X-Ray source. Stage weight: ~6.5kg.

CT500 (DEBEN)

The CT500 500N in-situ tensile stage for µXCT applications is a modular tensile and compression testing system with a maximum extension of 10mm and a 500N load cell with an accuracy of 1% (of full-scale range). The actuator speed ranges from 0.1mm/min to 1.0mm/min. The stage is equipped with an environmental chamber. Size: 87mm diameter, 86mm to the bottom of the tube, tube length to suit X-Ray source. Stage weight: ~1.0kg.

FT-RS1002 Microrobotic system (FEMTOTOOLS)

The FT-RS1002 Microrobotic System is a versatile and reconfigurable micromechanical testing and robotic handling system for the investigation of microscopic samples in multiple directions (horizontal, vertical, angles), with force measurement ranging from 5 nN to 100 mN. The system can move 26 mm in x-y-z direction with nanometer resolution and has a displacement sensing ranging from 5 nm to 26 mm.

LSM 880 with Airyscan (Zeiss)

The LSM 880 with Airyscan combines fast super-resolution and sensitive confocal image acquisition. Its novel detector design results in four-to-eight times improvement in signal-to-noise ratio (SNR), while simultaneously achieving a 1.7x increase in resolution at increased acquisition speeds of 27fps (at 480 x 480 pixels).

EVO MA10 (Zeiss)

The Zeiss EVO MA10 is a Scanning Electron Microscope (SEM) with a LaB6 electron source for micro-to-nano-scale imaging of a wide range of materials; chemical analysis by energy dispersive X-ray spectroscopy; and mineralogical and structural analysis by electron backscatter diffraction. A second SEM with W-filament electron source provides routine imaging of micro-materials.
