Across
  1. 7. The portion of the hair that is above the bulb but still below the skin
  2. 11. Produced as a result of two mirrors located inside of a CLM. As a result, the view of the specimen will appear upside down and backwards
  3. 14. A cuticle pattern in which it appears like several spikes at each level
  4. 16. Magnifying lens on a CLM: high, medium, and low power
  5. 18. A handle located between the eyepiece and the stage on a CLM
  6. 20. The microscope used to view larger bulkier items. This microscope has a maximum magnification of 125X
  7. 21. A medulla pattern that has consistent breaks
  8. 22. The objective lens that has the same magnification power as the eyepiece
  9. 24. The microscope that provides the greatest magnification power of all microscopes at 500,000X. This microscope requires a vacuum system and does not provide the real color of the specimen
  10. 26. The objective lens that has a magnification power of 40X
  11. 27. The innermost layer of hair that has unique patterns. This layer is the thickest layer in animal hair and is used to determine if it is animal or human hair by dividing the thickness of this layer by the thickness of the entire hair
  12. 28. A medulla pattern that has no breaks
Down

  2. 2. The microscope that is used to analyze/compare the colors of various specimens: paint, ink, etc..
  3. 3. A cuticle pattern appears as single scales at each level
  4. 4. The multiplication of the magnification power of the eyepiece and the magnification of the objective lens
  5. 5. The removal of the all air inside of a chamber where the specimen with be placed
  6. 6. A round part on a CLM where the objective lens are connected to the microscope. This part is rotated to change the magnification power.
  7. 8. The thickest layer of hair in human hair. This is the layer that contains the color pigments in hair

  14. 19. The smaller adjustment knob that moves the stage up and down
  15. 23. Also known as the Eyepiece. Also acts as a magnifying lens with a 10X power
  16. 24. The flat platform/surface in which the glass slide/specimen sits on top of
  17. 25. The objective lens that usually has red colored writing on it
  18. 28. The knob used to adjust the clarity of the image. The larger knob that moves the stage up and down the most. This lens is not used during high power objective lens.
