|
What are the 2 types of electron microscopes |
Transmission and scanning |
|
|
|
Difference between scanning and transmission microscope |
Transmission- specimen has to be dehydrated and stained, 2D black & white image Scanning- electrons bounce off specimen and focused on screen, 3D black and white image, false colour can be added |
