Welcome to the Cambridge Virtual Scanning Electron Microscope (VSEM) Website

Virtual SEM is a research project being carried out in the University of Cambridge Department of Engineering (CUED). Its objective is to develop web-based teaching and training solutions for novice and experienced users of the Scanning Electron Microscope.

This is a demonstration site for VSEM technologies. On this site you may browse the Encyclopaedia of SEM science and operating procedure, use the SEM Simulator to hone your skills and examine samples, or work through informative training courses and assessments covering different aspects of the SEM.

We hope you find the site useful.
