5. Parts of the Scope Eye piece ----------------------
Objectives
Neck
Stage
Light
Base

6. Magnification Eye piece power of X10 Objectives Red power of 4
Yellow power of 10
Blue power of 40
Total power = eye piece x objective

7. Focus Course – large inside knob - to be used first
- start with stage low
and bring up
Fine – small outside knob
- makes picture crisp
- Clear image

8. Field of view
