Compound Light Microscope Series of lenses that use light to magnify images (usually 1000x) Can study dead or live organisms, no smaller than 2um. Used in conjunction with chemical stains & fluorescent dyes to enhance images Prologue: Packet #3

Electron Microscopes Use beams of electrons to produce images Up to 1000x more detailed than light microscopes Two main types:  SEM: scanning electron microscope Electrons bounce off of outside of object Produces 3-D image  TEM: transmission electron microscope Electrons pass through an object Produces 2-D image Prologue: Packet #3

Conditions Needed For Electron Microscope Use 1. Specimen must be looked at within a vacuum 2. Nothing alive can be placed in an electron microscope 3. Specimen must be covered in a fine film of metal
