Types Of
Microscopes
Compound light microscope


2 or more lenses
Light travels through objects


Stereomicroscope


Magnifies large items
that light cannot pass
through.
Has an eyepiece lens
for each eye


Allows 3 dimensional view
10x to 60x magnification
Scanning Electron Microscope (SEM)





Views 3 dimensional bodies
Cannot be viewed in color
Cannot view live specimens
Electrons bounce off specimen,
then picked up by computer
Up to 100 000x magnification
Examples of
SEM images
Ragweed Pollen
Ear Hairs
Ear Hairs Up Close
Red Blood Cells
White Blood Cell
Bacteria 1
Cat Flea
Cilia
Respiratory Cell Cilia
Salt Crystals
Sand Grains
Rainbow Trout Scales
Shark Scales
Yeast Budding
Tapeworm
Tapeworm Hooks
Transmission Electron Microscope (TEM)



Similar to SEM
Electrons pass through
specimen
Not 3 dimensional
