I know--you clicked on a picture of a stereomicroscope--not a scanning electron microscope. That's one piece of science equipment we don't have in the clubhouse. At least, not yet!
This site will take you behind the scenes and show you how a scanning electron microscope works. Don't miss the "Image Gallery," where you can see remarkable pictures of a weevil, a house fly foot, velcro, and a black widow claw.
These pictures will give you a whole new appreciation for fleas!
Here's a book with more great electron microscope views:

Journeys with an Electron Microscope,
