- 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)
- Live organisms
- Main disadvantage
- Low Resolution
- Prevents Scientists from gathering detailed information about internal cell structure
- Low Resolution
