  3. Dissecting Microscope magnification knob arm eyepiece head objective light focus knob base

  4. Compound Microscope • higher magnification • 40 to 1000 times larger than life • used to view fine detail on small, thin objects • light is transmitted through the object from underneath • usually use a slide to hold object

  5. Compound Microscope eyepiece objectives coarse focus knob stage fine focus knob light base

  6. Using the Microscope • do not move the microscopes • use only the fine focus knobs on the compound microscopes • focus SLOWLY • use both eyes (do not close one)
