Compound-More than one lens-Has own light
-Light must see through the sampleTypes of MicroscopesSlide6
Stereomicroscope/Dissecting-Do not need light to pass through object
-Low magnificationTypes of MicroscopesSlide7
Electron-Very powerful
-Passes electrons through an object rather than light-Coat with gold or platinum to attract particlesTypes of MicroscopesSlide8

Magnification of a Compound Microscope
Because you are looking through multiple lenses the lenses have a “compounding” effect.
The eyepiece always magnifies 10X

Always carry with 2 hands – one on the base and the other on the arm
Do not force knobsClick Nosepiece to the lowest (shortest) setting when done – otherwise known as the park positionCover the microscope when done
Microscope CareSlide25
Place the Slide on the Microscope
Use Stage Clips Click Nosepiece to the lowest (shortest) settingLook into the EyepieceUse the Coarse Focus
Using the MicroscopeSlide26
Follow steps to focus using low powerClick the nosepiece to the medium or longest objective
