Types of MicroscopesTypes of Microscopes

The models found in most schools, use compound lenses to magnify objects. The lenses bend or refract light to make the object beneath them appear closer.

Stereoscope Stereoscope

This microscope allows for binocular (two eyes) viewing of larger specimens.

Usually magnifies 10x to 20x

Can be used for thicker specimens

Creates a 3D view of specimen

Allows scientists to view a universe too small to be seen with a light microscope. SEMs do not use light waves; they use electrons (negatively charged electrical particles) to magnify objects up to two million times.

SEM creates a 3D view of specimen, but cannot view living specimens (process kills them)

SEM = “surface”

also uses electrons, but instead of

scanning the surface (as with SEMs)

electrons are passed through very thin

specimens.

TEM = "thin"
