Diaphragm 12. Light Source 13. Base Microscopes are used to magnify specimens that are too small to see with the unaided eye.

3. Functions: 1. Light Source – (D) provides light for viewing specimen 2. Stage – (B) Supports the slide 3. Stage Clips – (I) Hold slide in place 4. Coarse Adjustment Knob – (F) brings image into initial focus 5. Fine Adjustment Knob – (A) sharpens focus 6. Diaphragm – (C) Controls the amount of light passing through the stage 7. High Power Objective Lens – (H) 40X or 43X magnification 8. Low Power Objective Lens – (G) 10X magnification 9. Revolving Nosepiece – (E) Holds the objectives and can be rotated to change magnification.

4. Microscope Information Carry a microscope with one hand under the base and one hand on the arm. ARM BASE

5. Microscope Information Clean microscope lenses with lens paper only. LENSES

6. Total Magnification: Eyepiece (10X) x Low Power Objective (10X) = 100 X Eyepiece (10X) x High Power Objective (43X) = 430X Field of View: Area within the circle of light

7. How to Focus A Microscope: 1.Lower Stage using C.A.K. 2.“Click” low power obj. in place 3.Put slide on stage; secure w/ stage clips 4.Raise stage using C.A.K. until it can no longer move 5.Look through eyepiece & slowly roll the C.A.K. down until specimen appears. 6.Use F.A.K. to sharpen image To View Under High Power: 1.Use rev. nosepiece to switch to high power obj. lens 2.Adjust slide on stage until specimen is in field of view 3.ONLY use F.A.K. to focus image
