Microscope
What are the four types of microscope

- Compound
- Stereoscopic
- Electron
• Similar to a magnifying glass and has

Simple Microscope
• Lets light pass through an object and
then through two or more lenses.
Compound Microscope
• Gives a three dimensional view of an
object. (Examples: insects and leaves)
Stereoscopic Microscope
• Uses a magnetic field to bend beams of electrons instead of using
lenses to bend beams of light.
