Simple microscope and compound microscope are two types of light microscopes that mainly differ based on their lens and magnification system. A simple microscope uses a single lens and compound microscope uses two or more lenses to produce more magnification and clear visibility of the specimen.
In this article, we will discuss what is a simple microscope and compound microscope, and the difference between a simple and compound microscope.
A simple microscope is a basic optical instrument which uses a single convex lens with a short focal length to produce a magnified image of a small object. Simple microscopes use a biconvex lens to magnify the image of a specimen. Most common simple microscopes have a 10x magnification power.
A compound microscope is a high power (microscope with higher magnification) microscope that uses more than the lens in the microscope. Typically a compound microscope has objective lenses (usually 4X, 10X, 40X and 100X) and these are further enhanced by eyepiece lens (usually 10X).
A compound microscope uses objective lenses and eyepiece lenses to create a higher magnification - 40X, 100X, 400X and 1000X. A compound microscope is widely considered as one of the standard microscopes that can be used for several general purposes.

What is a Simple Microscope?
A simple microscope is a basic optical instrument which uses a single convex lens with a short focal length to produce a magnified image of a small object. Simple microscopes use a biconvex lens to magnify the image of a specimen. Most common simple microscopes have a 10x magnification power.
What is Compound Microscope?
A compound microscope is a high power (microscope with higher magnification) microscope that uses more than the lens in the microscope. Typically a compound microscope has objective lenses (usually 4X, 10X, 40X and 100X) and these are further enhanced by eyepiece lens (usually 10X).
A compound microscope uses objective lenses and eyepiece lenses to create a higher magnification - 40X, 100X, 400X and 1000X. A compound microscope is widely considered as one of the standard microscopes that can be used for several general purposes.
Difference Between Simple and Compound Microscope
| Simple Microscope | Compound Microscope |
| Meaning | |
| An optical instrument that uses a single convex lens to produce a magnified image. | An optical instrument that uses two or more lenses to produce a highly magnified image. |
| Lens System | |
| Uses a single convex lens with a short focal length. | Uses an objective lens system and an eyepiece lens. |
| Objective Lens | |
| Does not have a separate objective lens. Single lens performs the magnifying function. | Has one or more objective lenses, commonly 4×, 10×, 40×, and 100×. |
| Eyepiece | |
| The single convex lens is used for viewing and magnification. | Uses an eyepiece lens, commonly 10×, to further magnify the image formed by the objective lens. |
| Magnification | |
| Provides lower magnification compared with a compound microscope. | Provides higher magnification, commonly 40×, 100×, 400×, and 1000×. |
| Illumination | |
| Usually uses natural or external light to illuminate the specimen. | Usually uses a built-in light source to illuminate the specimen. |
| Specimen Preparation | |
| Can be used with relatively simple specimens and may require little preparation. | Usually requires a prepared specimen mounted on a glass slide. |
| Applications | |
| Used for basic observation and magnification of small plant parts, seeds, fibers, insects, and other specimens. | Used to observe plant cells, tissues, microorganisms, and other microscopic structures. |
| Complexity | |
| Has a simple optical design with a single magnifying lens. | Has a more complex optical system with multiple objective lenses, an eyepiece, and other optical components. |
