What is a microscope?
A microscope is an optical instrument used to observe small objects. It uses magnification technology to allow us to see details that are indistinguishable to the naked eye. Microscopes play an important role in scientific research, medical diagnosis, education and other fields. This article will combine the hot topics and hot content in the past 10 days to introduce in detail the definition, classification, uses and latest technological progress of microscopes.
1. Definition and classification of microscopes
A microscope is an instrument that uses optical or electronic technology to magnify tiny objects. According to working principles and uses, microscopes can be divided into the following categories:
| Type | Working principle | Main purpose |
|---|---|---|
| optical microscope | Magnifying objects using visible light and lens systems | Biology, Medicine, Materials Science |
| electron microscope | Using electron beams instead of light provides higher resolution | Nanotechnology, Materials Science |
| Fluorescence microscope | Use fluorescent markers to visualize specific structures | cell biology, immunology |
| confocal microscopy | Obtaining 3D images through laser scanning | Neuroscience, medical research |
