  • Light Microscopes
    • How is the image formed?
      • 1. Light passes from a bulb through the condenser lens.
      • 2. The light travels through the specimen.
      • 3.The beam of light is focused through the objective lens
      • 4. The light is now focused through the eyepiece lens.
      • 5. A live image can be viewed.
    • Specimen must be think and transparent
      • This allows the light to travel through
    • Use a number of lenses to produce an image
      • The image can be viewed through an eyepiece
    • Have a number of objective lenses.
      • The lenses can be rotated
      • The magnification varies
        • x10
        • x4
        • x100
      • Eyepiece can provide a further magnification of x10
    • Used to view a wide range of specimens
      • Live organisms
        • Euglena and Daphnia
        • Smear and Red Blood Cells (RBC)
    • Main disadvantage
      • Low Resolution
        • Prevents Scientists from gathering detailed information about internal cell structure
