  1. Microscope Basics

  2. Ocular lens(Eyepiece)

  3. Ocular lens(Eyepiece) • Body Tube

  4. Ocular lens(Eyepiece) • Body Tube • Nosepiece • Holds the HIGH- and LOW- power objective LENSES; can be rotated to change MAGNIFICATION.

  5. Ocular lens(Eyepiece) • Body Tube • Nosepiece • Holds the HIGH- and LOW- power objective LENSES; can be rotated to change MAGNIFICATION. • OBJECTIVE LENSES • Magnification ranges from • 10 X to 40 X

  6. Ocular lens(Eyepiece) • Body Tube • Nosepiece • Holds the HIGH- and LOW- power objective LENSES; can be rotated to change MAGNIFICATION. • OBJECTIVE LENSES • Magnification ranges from • 10 X to 40 X • STAGE CLIPS • HOLD the slide in place

  7. Ocular lens(Eyepiece) • Body Tube • Nosepiece • Holds the HIGH- and LOW- power objective LENSES; can be rotated to change MAGNIFICATION. • OBJECTIVE LENSES • Magnification ranges from • 10 X to 40 X • STAGE CLIPS • HOLD the slide in place • DIAPHRAGM • Regulates the amount of LIGHT on the specimen

  8. Ocular lens(Eyepiece) • Body Tube • Nosepiece • Holds the HIGH- and LOW- power objective LENSES; can be rotated to change MAGNIFICATION. • OBJECTIVE LENSES • Magnification ranges from • 10 X to 40 X • STAGE CLIPS HOLD the slide in place • DIAPHRAGM Regulates the amount of LIGHT on the specimen • LIGHT SOURCE Projects light UPWARDS through the diaphragm, the SPECIMEN, and the LENSES

  9. Ocular lens(Eyepiece) • Body Tube • Nosepiece • Holds the HIGH- and LOW- power objective LENSES; can be rotated to change MAGNIFICATION. • OBJECTIVE LENSES • Magnification ranges from • 10 X to 40 X • STAGE CLIPS HOLD the slide in place • DIAPHRAGM Regulates the amount of LIGHT on the specimen • LIGHT SOURCE Projects light UPWARDS through the diaphragm, the SPECIMEN, and the LENSES • BASE • Supports the MICROSCOPE

  10. Ocular lens(Eyepiece) • Body Tube • Nosepiece • Holds the HIGH- and LOW- power objective LENSES; can be rotated to change MAGNIFICATION. • OBJECTIVE LENSES • Magnification ranges from • 10 X to 40 X • STAGE CLIPS HOLD the slide in place • DIAPHRAGM Regulates the amount of LIGHT on the specimen • FINE ADJUSTMENT KNOB • Moves the stage slightly to SHARPEN the image • LIGHT SOURCE Projects light UPWARDS through the diaphragm, the SPECIMEN, and the LENSES • BASE • Supports the MICROSCOPE

  11. Ocular lens(Eyepiece) • Body Tube • Nosepiece • Holds the HIGH- and LOW- power objective LENSES; can be rotated to change MAGNIFICATION. • OBJECTIVE LENSES • Magnification ranges from • 10 X to 40 X • STAGE CLIPS HOLD the slide in place • COARSE ADJUSTMENT KNOB • Moves the stage up and down for FOCUSING • DIAPHRAGM Regulates the amount of LIGHT on the specimen • FINE ADJUSTMENT KNOB • Moves the stage slightly to SHARPEN the image • LIGHT SOURCE Projects light UPWARDS through the diaphragm, the SPECIMEN, and the LENSES • BASE • Supports the MICROSCOPE

  12. Ocular lens(Eyepiece) • Body Tube • Nosepiece • Holds the HIGH- and LOW- power objective LENSES; can be rotated to change MAGNIFICATION. • OBJECTIVE LENSES • Magnification ranges from • 10 X to 40 X • STAGE • Supports the SLIDE being viewed • STAGE CLIPS HOLD the slide in place • COARSE ADJUSTMENT KNOB • Moves the stage up and down for FOCUSING • DIAPHRAGM Regulates the amount of LIGHT on the specimen • FINE ADJUSTMENT KNOB • Moves the stage slightly to SHARPEN the image • LIGHT SOURCE Projects light UPWARDS through the diaphragm, the SPECIMEN, and the LENSES • BASE • Supports the MICROSCOPE

  13. Ocular lens(Eyepiece) • Body Tube • Nosepiece • Holds the HIGH- and LOW- power objective LENSES; can be rotated to change MAGNIFICATION. • ARM • Used to SUPPORT the microscope when carried • OBJECTIVE LENSES • Magnification ranges from • 10 X to 40 X • STAGE • Supports the SLIDE being viewed • STAGE CLIPS HOLD the slide in place • COARSE ADJUSTMENT KNOB • Moves the stage up and down for FOCUSING • DIAPHRAGM Regulates the amount of LIGHT on the specimen • FINE ADJUSTMENT KNOB • Moves the stage slightly to SHARPEN the image • LIGHT SOURCE Projects light UPWARDS through the diaphragm, the SPECIMEN, and the LENSES • BASE • Supports the MICROSCOPE

  14. Ocular lens(Eyepiece) • Body Tube • Nosepiece • Holds the HIGH- and LOW- power objective LENSES; can be rotated to change MAGNIFICATION. • ARM • Used to SUPPORT the microscope when carried • OBJECTIVE LENSES • Magnification ranges from • 10 X to 40 X • STAGE • Supports the SLIDE being viewed • STAGE CLIPS HOLD the slide in place • COARSE ADJUSTMENT KNOB • Moves the stage up and down for FOCUSING • DIAPHRAGM Regulates the amount of LIGHT on the specimen • FINE ADJUSTMENT KNOB • Moves the stage slightly to SHARPEN the image • LIGHT SOURCE Projects light UPWARDS through the diaphragm, the SPECIMEN, and the LENSES • BASE • Supports the MICROSCOPE

  15. What happens as the power of magnification increases? Power = 10 x 10 = 100 Power = 10 x 40 = 400 Power = 10 x 4 = 40
