The Virtual SEM for Students
These pages use JavaScript to create the
illusion of controlling a Scanning Electron Microscope (SEM). You must be
using Netscape 3.0 or higher and JavaScript must be enabled. Here are the
instructions for using the microscope:
- Choose a sample, put it in the microscope chamber.
- Activate the vacuum pump to remove air from the sample chamber and
electron beam path.
- Use the audio plug-in inserted by your browser in the box below to
hear the sound of the SEM vacuum pump. Play the sound by clicking the
play button on your plug-in (usually a triangle arrow pointing to the
right).
- While operating the microscope, you will see the SEM Control Window
- SEM Control Panel: Slide your mouse pointer over the Magnification
Controls to zoom in on the specimen.
- Image Capture: When you click a Magnification Control button,
the full-sized image will be captured to this window.
- When you are finished viewing the sample, shut down the microscope
using the Shut Down button in the SEM Control Panel window.
- The microscope is now ready to view the sample. Use the button below
to turn on the electron beam:
You are now qualified to be an Expert Microscopist. There are more samples
waiting to be studied.
Notes:
- Actual magnification values depend on the size of your computer monitor.
The values given are from the original SEM settings. They should be
used as a relative measure of magnification for the set of images (e.g.
600x is magnified twice as much as 300x).
