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 microsc...
