Introduction to Microscopy
Microscopy is the technique of using microscopes to view objects that are too small to be seen with the naked eye. Microscopes have revolutionized various fields, including biology, chemistry, medicine, and material science. A microscope is an instrument that produces magnified images of small objects.
It consists of lenses, a stage to hold the specimen, and a light source.
Types of Microscopes
There are various types of microscopes, each with its own principles, magnification range, and applications. Here is a table summarizing some common types:
| Type | Definition | Magnification Range | Applications |
|---|---|---|---|
| Light Microscope | Uses visible light to illuminate the specimen | 10x
|
Biology, medicine, microbiology |
| Electron Microscope | Uses a beam of electrons to create an image | 100,000x
|
Materials science, nanotechnology |
| Fluorescence Microscope | Uses fluorescent dyes to highlight specific structures | 100x
|
Cell biology, immunology |
| Confocal Microscope | Uses a laser to scan the specimen and create a 3D image | 100x
|
Neuroscience, developmental biology |
Matching Characteristics to Microscope Types
Different microscopy techniques have specific characteristics related to sample preparation, imaging, resolution, and accessibility. Here is a list of characteristics and their corresponding microscope types:
