Summary Introduction

To distinguish: The principle between light microscope and transmission electron microscope.

Introduction: A microscope is an instrument that is used to view the objects that are too small to be viewed with naked eyes. The components of the microscope are eyepiece, arm, base, illuminator, stage clips, nose piece, objective lens, and so on. There are two types of microscopes, namely, light microscope and electron microscope.

Explanation of Solution

The differences between the principle of light microscope and electron microscope are described as follows:

Light microscopeTransmission electron microscope
  • It uses light for viewing the image.
  • It uses the electrons for viewing the image.
  • It is based on the principle of light that is focused through the specimen and then through the objective and ocular lens.
  • The electrons are focused on the specimen using the magnets which then pass through the sense region of the specimen and are deflected by regions that have a greater concentration of structures.
  • The resolving power is low.
  • The resolving power is high.
