light microscope
Definition
- Noun:
- An optical instrument that uses visible light and a system of lenses to magnify the image of a small object: A light microscope is a device that allows users to see details of tiny structures that are not visible to the naked eye by illuminating them with light and enlarging their image through lenses.
Usage
- The term "light microscope" is used to distinguish this common type of microscope from other types, such as electron microscopes. It is typically used in scientific, educational, and medical contexts.
- It functions as a countable noun (e.g., a light microscope, several light microscopes).
Examples
- Noun:
- The biology students examined plant cells using a standard light microscope.
- Before the invention of more powerful instruments, the light microscope was the primary tool for microbiological discovery.
Advanced Usage
- "Compound light microscope": A more specific term for the most common type of light microscope, which uses multiple lenses to compound (multiply) the magnification.
- A compound light microscope can magnify a specimen up to 1000 times.
Variants and Related Words
- Microscope (n): The general term for any instrument used to see small objects. A light microscope is a specific type of microscope.
