Microscopy: A Brief Overview

Microscopy is the scientific study of small objects using a microscope. It allows us to observe and analyze things that are too small to be seen with the naked eye.  

History of Microscopy

• First Compound Microscope: Developed by Zacharias Janssen in 1595 in Holland.
• Magnification: Initially ranged from 3X to 9X.

Key Terms in Microscopy

• Magnification: The making of an object seem larger than it is.
• Resolving Power (Resolution): The ability of a microscope to distinguish between two closely spaced objects.
• Human eye can differentiate between two points at least 0.1 mm apart.

 

Understanding Magnification and Resolution

• Magnification: Increases the size of an object, making it easier to see.  
• Resolution: Determines the clarity of the image. A higher resolution provides greater clarity and precision.
• Limitations: Even with high magnification, if the resolution is poor, the image will be blurry.

Note: To achieve both high magnification and high resolution, advanced microscopy techniques and equipment are often used, such as electron microscopes and confocal microscopes.
