🔍 Advantages and Limitations
💡 Light Microscope
✅ Advantages:
- Can observe living specimens
- Color images possible
- Relatively inexpensive
- Easy to use and maintain
- Portable
- Simple specimen preparation
- Can view specimens in real-time
❌ Limitations:
- Limited magnification (×1500 max)
- Limited resolution (200 nm)
- Cannot see internal organelle detail
- Dependent on light wavelength
- Specimens must be thin enough for light
⚡ Electron Microscope
✅ Advantages:
- Very high magnification (×2M)
- Excellent resolution (0.05 nm)
- Can see internal organelle structure
- Reveals fine details of cell ultrastructure
- SEM gives 3D surface images
❌ Limitations:
- Cannot view living specimens
- Black and white images only
- Very expensive to buy and maintain
- Requires special training
- Complex specimen preparation
- Requires vacuum chamber
- Large and non-portable
- Specimens must be completely dehydrated
