Study of Simple and Compound Microscope

In this study of simple and compound microscope post we have briefly explained about difference between simple microscope and compound microscope.

What makes a difference between compound microscope and simple microscope? The number of lenses on each of these two microscopes, as well as the magnification level, can be used to determine the difference. Cost and portability are two more distinguishing elements.

Study of Simple and Compound Microscope

A compound microscope is a magnifying instrument that uses two types of lenses to magnify an object with multiple zoom levels of magnification. The objective lens, which provides a resolved image, and the eyepiece lens, which magnifies the object, makes up the scope. 

A simple microscope is a magnifying instrument with only one lens to magnify objects. Jewelry eyepieces, reading glasses, and pocket magnifiers are examples of basic microscopes. The following eleven points are the differences between a Compound Microscope and Simple Microscope:

Characteristics

Simple Microscope

Compound Microscope

Invented by

Around 1670, Antony van Leeuwenhoek invented the first simple microscope.

Hans and Zacharias Janssen invented the first compound microscope in 1950.

Number of lenses

A single lens can be used to view objects.

The term “compound” refers to the use of numerous (3 to 5) lenses in a microscope.

Condenser lens

A condenser lens is not present in simple microscopes.

A condenser lens is included in the compound microscope.

Light source

In basic microscopes, the light source is natural.

When tiny objects need to be seen, an illuminator is used as a light source.

Mirror type

A concave mirror is used in a basic microscope.

On one side of a compound microscope, a plane mirror is used, while on the other, a concave mirror is used.

Level of magnification

The simple microscope’s entire magnification is restricted to one lens.

The total magnification of a compound microscope is the combination of the objective lens and eyepiece magnifications.

Magnifying power           

The simple microscope’s entire magnification is restricted to one lens. Up to 300X magnification.

The total magnification of a compound microscope is the sum of the objective lens and eyepiece magnifications. Up to 2000X magnification.

Adjusting Magnification

It just has one adjustment screw that allows you to move the limb up and down to focus on the object.

Coarse Adjustment: This is used to focus on an object quickly.

Fine Adjustment: It is used to focus on objects in a fine and crisp manner.

Structure

The microscope is held by a small stand that is hollow cylindrical and connects to the base.

The microscope is held in place by a curved arm.

Training

Simple microscope is used at a basic level, where there is no rigorous requirement of research.

Due to an added lens to a compound one, professionals use this for research purposes.

Used

Only useful for minor tasks like magnifying small letters while reading.

Has a wide range of applications, including analysing the structure of various objects, such as cells in live organisms.

Summary

A simple microscope has only one biconvex lens, which usually has a low focus length. An ordinary microscope is used to magnify an item that fits inside its focus length. A compound microscope, on the other hand, has two sets of lenses: an ocular or eyepiece lens and objective lenses.

A simple microscope has only one magnification level, which is not adjustable and is equal to the lens being used. 

The compound microscope has a much higher magnification level and may be adjusted. It has a rotating nosepiece that stores two to four objective lenses and enables for easy selection of the various objective lenses. 

Unlike a simple microscope, this implies that there are two to four distinct zoom settings to pick from. 

Its overall magnification is calculated by multiplying the eyepiece lens by the objective lens used. A total magnification of 400X can be obtained by combining a 10x eyepiece lens with a 40x objective lens.

A compound microscope can be used to see items in greater detail, such as the features of cells in living organisms, because it has a higher magnification capability. 

On the other hand, a simple microscope can only be used to expand objects, such as when reading small characters.
