The amazing Scanning Electron Microscope

Most of the fantastic images in the Talking Electron Microscope were created with a Scanning

Electron Microscope.

Conventional microscopes use glass lenses to bend light to create a magnied image. The

Scanning Electron Microscope bombards the image with electrons instead of light waves.

The resulting images are super-detailed 3-dimensional images that are at much higher

magnications than can be accomplished with a light microscope.

The images in the Talking Electron Microscope reveal the amazing detail and complexity of

living things and tiny structures in the world all around us.
