We have teamed up with award-winning electron microscopist Dr. Dennis Kunkel to produce a series of interactive tutorials that explore various aspects of virtual Scanning Electron Microscopy (vSEM). Use the tutorial below to discover how specimens appear when magnified in the virtual SEM.

When the tutorial is first loaded, the specimen is out of focus and brightness and contrast are not optimized. Use the Focus slider to achieve focus and the Contrast and Brightness sliders to optimize specimen appearance. Next, use the Magnification slider to slowly increase the magnification. Higher magnification images load in the background, so please be patient and allow some time for these images to download into your browser cache. Use the pull-down menu bar to change specimens. Each time a new specimen is loaded into the browser, the focus, brightness, and contrast controls are randomly reset to simulate the situation in a real microscope.

For questions about Scanning Electron Microscopy, email Dr. Dennis Kunkel at the University of Hawaii or visit his website: Dennis Kunkel's Microscopy for a sampling of optical and electron microscopy images.
