In 1965, the first commercial Stereoscan SEM was built by Cambridge Instrument Company, a UK based predecessor company of Carl Zeiss Microscopy Ltd.
To mark the anniversary of this very first SEM sale 50 years ago, and celebrate the contributions to scientific research across so many fields and industries made possible through scanning electron microscopy, ZEISS hosted a celebratory event in Cambridge yesterday.
During a morning of talks, lunch, and a museum tour, customers and specialists from many disciplines had the chance to meet scientists who worked on the development of the first commercial SEMs.
With 50 years of continuous growth and development, the SEM has become ever more versatile, and is now firmly established as an indispensable tool for advanced research across many scientific disciplines. With new industrial applications emerging every year, the SEM is also a vital part of research & development, and quality control & analysis across an extensive range of industries around the globe.
From its early home in materials science, the SEM established itself in the disciplines of electronics, forensics and archaeology. Over the years it has evolved into a key tool for food technologists, biologists, geologists and petrologists in the natural resources industries, adapting subtly to fulfil the discrete requirements of these individual applications.
Use of SEMs for process control and failure analysis is now widespread, with routine analysis on SEMs an integral part of the semiconductor and automotive industries, and manufacture more broadly.
Development still goes on: A direct descendant of the first microscopes produced in Cambridge in 1965 is the ZEISS EVO family. First launched in 2004, and widely accepted as the industry leading analytical platform, there are some developments soon to be unveiled for EVO offering more flexibility, ease of use, and further development of detectors.
The new ZEISS GeminiSEM family comes with a novel optical design. The Nano-twin lens delivers images with high contrast and sub-nanometer resolution. NanoVP allows the use of in-lens detection at pressures of up to 150 Pa. Even charging samples can now be imaged with high quality.
At the same time, NanoVP improves lateral resolution of EDS data, providing higher spatial resolution on chemical specimen composition, thus gaining more information from the sample.
