Zeiss Gemini Technology 30th Anniversary Special | Dialogue with Professor Gong Ming from the University of Science and Technology of China

Zeiss Gemini Electronic Optics Technology（The following refers to Zeiss Gemini technology）Since its inception, it has continuously helped users easily achieve sub nanometer resolution imaging and analysis work.

On the occasion of the 30th anniversary of the birth of Zeiss Gemini technology, follow Zeiss to visit Professor Gong Ming andZeiss Field Emission Scanning Electron Microscope GeminiSEM SeriesThe research journey.

What assistance has Zeiss field emission scanning electron microscopy provided in your work and research?

Our Zeiss field emission scanning electron microscope GeminiSEM 500 has been installed and used for over 6 years, providing over 2000 hours of service to teachers and students both inside and outside the school every year. We have completed a lot of work on this device, not only providing service support for multiple research groups in the school, including academician research groups, but also sharing machine time to support industrial customers in need.This includes providing service support from the academician research group and sharing machine time to support industrial customers in need.

In addition, Zeiss is equipped withLocalized Application and Service EngineerWith such technological and service support, we are among the top universities in the countryOffering training courses on scanning electron microscopy experiments for graduate studentsTo enable students to align with international standards, cultivate their hands-on skills and ability to independently operate large equipment to solve scientific research problems. Students who complete the course can not only earn corresponding credits, but also obtain certification qualifications. After arriving at various research institutes of the Chinese Academy of Sciences, they can directly obtain the qualification to operate scanning electron microscopes in the institutes with this certificate, which makes our courses very popular.

What are your favorite features of Zeiss field emission scanning electron microscopy?

I think Zeiss Gemini technology is a revolution in electron microscopy technology. The electron beam in traditional scanning electron mirrors needs to undergo multiple convergences in the tube and then be focused onto the surface of the sample for scanning imaging, while the parallel electron beam technology of Gemini tube can be used forEnsure beam current while also having excellent resolutionAfter the launch of Gemini technology, as customers, we have gone from feeling novel to cognitive recognition, and now we have become deeply rooted in the hearts of Zeissplace.
In addition to the advantages of Gemini tube, it also has a sufficiently large sample chamber and corresponding multiple flange interfaces, which allows us toVery flexible to install some third-party accessories in the electron microscopeFor example, the Zeiss field emission scanning electron microscope GeminiSEM 500 has energy spectra and EBSD, as well as our ownIn situ stretching heating table developedWaiting, conducting in-situ mechanics and in-situ EBSD experiments is very convenient and safe, providing customers with many options for later functional expansion and development.
