Description
ZEISS GeminiSEM is a family of field emission scanning electron microscopes (FE-SEM) designed for the highest demands in sub-nanometer imaging, analytics, and flexible sample handling. The system combines ultra-high resolution, efficient signal detection, and broad configuration capabilities for complex scientific and applied tasks.
GeminiSEM is intended for users who require not only high-quality electron imaging but also comprehensive sample characterization — from surface topography to material contrast, elemental composition, crystallography, and nanoscale structural features. Thanks to ZEISS Gemini electron optics, in-column Inlens detection, advanced analytical configuration, and support for complex, sensitive, and non-conductive samples, the system delivers consistently high performance across a wide range of applications.
