1. Microscopes:

2. 3 types Light Microscope SEM – Scanning Electron Microscope
TEM – Transmission Electron Microscope

4. Light Microscope Lens Magnification MULTIPLIES!!
EYE PIECE magnifies the specimen 10 times
OBJECTIVE LENS magnifies the specimen 40 times
TOTAL MAGNIFICATION = 400 times
because 10 eyepiece x objective lens =

5. S.E.M.

6. Shoots beam of e- at the object. The electrons bounce back
Shoots beam of e- at the object. The electrons bounce back. Detectors form the 3-D image.

12. T.E.M.

13. Transmission Electron Microscope T.E.M.

14. T.E.M.
Same as S.E.M . (shooting a beam of electrons at the specimen), but with T.E.M. we view a thin slice of the specimen.
We can see internally…
