Amazing Microscope Images

Light Microscopes

• Use lenses to bend light and magnify images by a factor of roughly 100-fold
• Can be used to view living specimens in natural colour
• Chemical dyes and fluorescent labelling may be applied to resolve specific structures

Electron Microscopes

• Use electromagnets to focus electrons resulting in significantly greater magnifications and resolutions
• Can be used to view dead specimens in monochrome (although false colour rendering may be applied)
  • Transmission electron microscopes (TEM) pass electrons through specimen to generate a cross-section
  • Scanning electron microscopes (SEM) scatter electrons over a surface to differentiate depth and map in 3D
