  1. Summerland Secondary School Science 10 Microscopes

  2. The Northwest Microscope

  3. The Ocular Lens

  4. The Ocular Lens OcularMagnification = ___ X

  5. The Ocular Lens OcularMagnification = 10 X

  6. The Low Power Objective Lens Magnification = 4 x

  7. Ocular magnification x Objective magnification = Total Magnification Eg. For the low power objective: 4 Ocular magnification x Objective magnification Total Magnification= 10 x 4 =

  8. Ocular magnification x Objective magnification = Total Magnification Eg. For the low power objective: 4 Ocular magnification x Objective magnification Total Magnification= 10 x 4 = 40x

  9. The Medium Power Objective Lens

  10. Objective Magnification = 10 x The Medium Power Objective Lens

  11. Total Magnification = Ocular magnification x Objective magnification 10 x 10 = 100 x

  12. The High Power Objective Lens Magnification = 40 x

  13. The High Power Objective Lens Magnification = 40 x Total Magnification = 10 x 40 = 400 x

  38. This is the Cover !

  39. Put the cover over the microscope before you leave!!

  40. Steps in Viewing a Prepared Slide

  41. Steps in Viewing a Prepared Slide • Click LOW power objective on top of the center of the stage.

  42. Steps in Viewing a Prepared Slide • Click LOW power objective on top of the center of the stage. • Clip Slide under clips

  43. Steps in Viewing a Prepared Slide • Click LOW power objective on top of the center of the stage. • Clip Slide under clips • 3. Align so object being viewed is right in the very center.

  44. Steps in Viewing a Prepared Slide • Click LOW power objective on top of the center of the stage. • Clip Slide under clips • 3. Align so object being viewed is right in the very center. • 4. Adjust focus with course and then fine adjustment. Make sure the object is in the very center before you switch to a higher magnification.

  45. Steps in Viewing a Prepared Slide 6. Click Medium (10 x ) objective lens Into place above the slide.

  46. Steps in Viewing a Prepared Slide 6. Click Medium (10 x ) objective lens Into place above the slide.7. Focus with fine adjustment knob. (You may have to move the slide a bit to keep the object in the center)

  47. Steps in Viewing a Prepared Slide 6. Click Medium (10 x ) objective lens Into place above the slide.7. Focus with fine adjustment knob. (You may have to move the slide a bit to keep the object in the center)8. If you require, switch to HIGH power objective. Do NOT use the course adjustment knob!!! MAKE SURE THE LENS DOES NOT TOUCH THE SLIDE !!!!
