The microscope is a tool used to make things look bigger. People often use it in labs to study small things. Last time, we talked about different kinds of microscopes. Now, let’s dive into the compound microscope and learn more about it.
What is a Compound Microscope?
A compound microscope is a type of microscope that has two sets of lenses, allowing it to produce a detailed image of the sample in two dimensions.
The term “compound” indicates that it uses multiple lenses. There are two main types of microscopes: compound and simple. The key difference between them is that a simple microscope has just one lens, while a compound microscope has multiple lenses.

Parts of Compound Microscope
The compound microscope is mainly used for studying tiny details of cells, tissues, or parts of organs. It has two main parts:
Non-optical parts:
- Base: The bottom part that holds the whole microscope.
- Pillar: The part connecting the base and the arm.
- Arm: A metal handle supporting the stage and body tube.
- Inclination Joint: Allows tilting the microscope for comfortable viewing.
- Stage: A platform where slides with samples are placed.
- Body Tube: Holds the lenses.
- Draw Tube: Holds the eyepiece.
- Rack and Pinion: Adjusts focus.
- Adjustment Screws: Fine-tune focus.
- Automatic Stop: Prevents damage to the lenses.
Optical parts:
- Diaphragm: Controls light.
- Condenser: Focuses light.
- Reflector: Directs light onto the sample.
- Objective Lenses: Magnify the sample.
- Ocular Lens: Eyepiece for viewing.
There are different types of objective lenses for various levels of magnification and ocular lenses for different magnification strengths. Binocular head makes viewing easier with two eyepieces and special mirrors and prisms.
