Parts of a Microscope

Today's Learning Goals: To identify, name and describe the function of all parts on a compound light microscope

*Mini-test on this next class!






Parts of a Microscope

1. Eyepiece/Ocular Lens – The lens into which the user looks to see the specimen.
2. Diopter Adjustment – Used to alter focus between eyepieces to
3. Arm – A supporting piece of the optical microscope mounted upon the base.
4. Nose  Piece – A rotating turret for switching between objective lenses.
5. Objective Lenses – Lenses with various magnification strengths.
6. Slide Holder – Clips to keep the slide in place.
7. Stage – The platform holding the specimen slide.
8. Coarse Focus – Brings specimen into general focus.
9. Fine Focus – Fine tunes the focus of the specimen.
10. Condenser – Focuses light from the light source onto the specimen.
11. Iris Diaphragm – An opaque iris composed of blades made to pass light through an aperture.
12. Base – The supporting block of the light microscope.
13. Light Source –  A light or a daylight directed via a mirror.
14. On/Off Switch – You probably understand what this does:)

Additional Questions:

1. Explain briefly where the name compound light microscope comes from.
2. What is the total magnification of a compound light microscope if the eyepiece/ocular has a magnification of 5x and the objective lens has a magnification of 250x? Show your calculations.
