1. The Microscope

2. Compound Microscope Robert Hooke – 1665 Piece of cork
Observation – cells are filled with juices

3. Anton Van Leeuwenhoek 1670 – pond water Discovered animalcules
Now called microorganisms

4. Two Types of Microscopes
Light
Glass lens and light rays
Electron
Electrons instead of light

5. Parts Arm Base Oculars Objectives Stage Coarse Adjustment
Fine Adjustment
Light Source

7. Procedures for Transport
Two hands!!!!
Arm
Base

8. Using the Microscope Start on 4x scanning objective!
Use Coarse Adjustment
After focus you can move up in magnification to 10X
Use Fine adjustment

9. Storing Microscopes Turn off light source
Wrap cord around bottom of arm
Lower stage
4X objective
Cover

10. Magnification
To determine your magnification…you just multiply the ocular lens by the objective lens
Ocular 10x Objective 40x:10 x 40 = 400
So the object is 400 times “larger”
Objective Lens have
their magnification
written on them.
Ocular lenses usually magnifies by 10x
