GeminiSEM – Field Emission Scanning Electron Microscopes (FE-SEM)

• GeminiSEM 360 is the ideal instrument for a core facility, delivering maximum versatility for materials & life science, and industry.
• The eponymous electron optical design Gemini 1 brings you the benefit of surface sensitive, high resolution images providing excellent resolution at low voltage and great speed at high probe current.
• Gather high resolution, surface- and compositional information, even on sensitive samples by using Inlens secondary and backscatter electron imaging simultaneously.
• When aiming to image non-conducting samples under lower vacuum, so-called variable pressure, there is no need to forgo Inlens contrast: NanoVP guarantees maximum versatility enabling Inlens imaging without charging.

Unrivalled User Experience

• GeminiSEM 460 is made for your most exacting analytical tasks and enables efficient analysis and unattended workflows.
• Perform high-resolution imaging and analytics rapidly: switch seamlessly from low current-low kV work to high current-high kV work, and back again utilizing the Gemini 2 column.
• Characterize any specimen comprehensively by using multiple detectors in parallel.
• For efficient analysis exploit the versatile chamber and choose appropriate analytical detectors.
• Use the new VP mode and turn up the current to obtain EBSD maps with indexing rates of 4000 patterns/s.
• Investigate chemical composition and crystal orientation with two diametrically opposite EDS ports and a coplanar EDS/EBSD configuration. Count on high speed, shadow-free mapping.

Customized, Automated Workflows

• With such powerful analytics at hand workflow automation becomes key. Create and configure automated experiments of your own with the Python scripting API from ZEISS.
• Modify experiments and customize the outcome to your own requirements.
• Make the most of STEM tomography: combine automated tilting and rotation with feature tracking. Produce 3D tomograms with nanometer-scale resolution after all aligned images are then sent to a proprietary 3D reconstruction software.
• When you need to test materials to their engineering limits, ZEISS puts an automated in situ heating and tension experimental lab at your disposal: it lets you observe materials under heat and tension automatically while plotting stress-strain curves on the fly

Your Pathway to Even More Possibilities

• Expand your analytical capabilities across materials and life sciences with exceptionally high, tunable current density, even at low kV – based on the Gemini 2 design.
• Take advantage of being able to adapt the system with a wide variety of accessories. The versatile chamber can be configured not only with analytical equipment but also with devices for in situ experiments, cryo-imaging and nanoprobing. storage lets you manage projects centrally by connecting data from different instruments in your lab.
• This lets you benefit from the ability to accommodate many configurations and upgrades at any point during the lifetime of your instrument.
• All GeminiSEMs are plugged into the ZEISS ZEN core ecosystem giving you access to ZEN Connect, ZEN Intellesis and ZEN’s analytical modules providing reporting and GxP workflows.

• Gemini 3 enables magnetic field-free imaging with sub 1 nm resolution below 1 kV – without the need for sample biasing or monochromation. It includes the Nano-twin lens and the new electron optical engine Smart Autopilot.
• Achieve images of non-conducting matter with a new variable pressure mode and detection system: ensure fast results and preserve features by bringing vacuum-sensitive specimens into the chamber through the new Gentle Airlock in VP mode.
• Analyze delicate samples with ease by leveraging the new, large chamber with dual EDS ports. Produce fast, shadow-free mapping ensured by an optimum detector solid angle.
