A magnifying glass is a simple microscope that uses one lens for magnifying small objects like small alphabets.
Simple microscopes have real-life applications in the Biology lab, where we employ this device for observing the internal structure of plants, animals, and microorganisms.
If we talk about the compound microscope, the purpose of this microscope is the same as that of the simple microscope; however, it uses multiple lenses to magnify real-world objects that are invisible to the naked eye.
Here, we will learn to distinguish between a simple microscope and a compound microscope.
The difference between simple and compound microscope lies here under:

From the above image, we can observe that there are two lenses in a compound microscope.
Let’s say, you are doing a simple eye exercise by focusing on the tip of your finger and bringing it close to your eyes slowly. On bringing near to your eyes, i.e., before the least distinct vision (25 cm), the image becomes blurred. To get a magnified view of the same, we use a microscope.
Microscopes have wide real-life applications, let’s discuss the applications of the simple and compound microscope one-by-one:
It is used by watchmakers to obtain a magnified view of small parts of the watch.
It is used by jewelers to get a magnified view of the fine parts of jewelry.
A simple microscope is called the hand lens or the reading lens to obtain an enlarged view of hard-to-read small alphabets.
It is used by a dermatologist (a skin specialist) to examine various skin diseases.
It is used in studying soil particles (Pedology).
Compound microscopes are used to obtain a magnified view of objects at 40x to 1000x resolution, which is formed by the combination of the objective lens and the eyepiece.
The real-life applications of these microscopes are as follows:
Forensic labs: Crime cases are solved by drawing human cells and examining them under the compound microscope.
Compound microscopes are used in Pathology labs to detect diseases.
Around the year 1670, Antony van Leeuwenhoek invented the single-lens simple microscope that magnified up to 200x and achieved twice the resolution of the objects at those times because he crafted good quality lenses.
1. What is the Working Principle of the Compound Microscope?
Answer: A compound microscope is considered a light microscope.
The idea behind the working of the compound microscope is that a small object can be viewed by placing it beyond the focal length of the objective lens. A virtual, erect, and highly magnified image of the object is formed at the least distinct of vision, i.e., at 25 cm distance from the eye.
2. List the Types of Microscopes.
Answer: Microscopes are of various types with varying applications. Let’s discuss their types one-by-one:
Brightfield Transmitted Microscope (Mostly used microscope)
Phase Contrast Microscope (PCM)
Differential Interference Microscope (DIM)
Reflected Light Metallurgical (RLM)
3. How Does a Microscope Work?
Answer: Microscopes are the arrangement of tubes packed with lenses, curved pieces of glass that refracts light rays passing through them. A lens above the object or the objective lens and another lens near your eye is the eyepiece or ocular lens.
4. Why Do We Study a Microscope?
Answer: A microscope enables scientists to ascertain in-depth contact between the structures and functions at varying levels of resolution.
Microscopes have continued to be modified since they were first invented and used by the early scientist named Anthony Leeuwenhoek to observe microorganisms like bacteria, yeast, and blood cells.
