Magnification |
Enlarges objects invisible to the naked eye, revealing details and structures. |
Resolution |
Defines the level of detail visible – higher resolution allows for clearer distinction of fine structures. |
Illumination |
Uses light sources and lenses to illuminate and magnify the sample. |
Types of Microscopes |
- Light Microscope (Optical Microscope): Uses visible light for magnification, most common type in laboratories and classrooms.
- Electron Microscope: Utilizes beams of electrons for much higher magnifications and resolution, ideal for viewing structures at the atomic level.
- Scanning Electron Microscope (SEM): Creates detailed images of a sample’s surface by scanning it with an electron beam.
- Transmission Electron Microscope (TEM): Allows viewing very thin samples by transmitting electrons through them.
- Dissecting Microscope (Stereomicroscope): Provides a 3D view of a sample at lower magnification, suitable for examining larger objects.

Applications |
- Cell biology: Studying cell structure and organelles.
- Microbiology: Examining bacteria, viruses, and other microorganisms.
- Material science: Analyzing the microstructure of materials.
- Forensics: Examining evidence for trace materials and fingerprints.
- Medical diagnosis: Analyzing tissue samples for pathology.
