Parts of Microscope and Its Function and Labelled Diagram

To understand parts of microscope and its function, first learn about the history of the microscope. The microscope is a device that allows us to see small objects or details that are not visible to the naked eye. The first known microscope was invented in the early 17th century by Dutch scientist Antonie van Leeuwenhoek. Van Leeuwenhoek was a skilled craftsman who made his own microscopes using a single lens, which he mounted in a tiny metal frame. 

What are Microscopes?

The microscope is a scientific equipment used to examine samples too small to be seen with the human eye. They are commonly employed in research facilities for the purpose of examining microscopic creatures, cells, and other small samples. The focal power of the lens used in a microscope determines how much of an increase in size to expect while seeing the specimen. The level of magnification achieved depends on the type of lens used, as there are many different lenses with differing magnification capabilities.

14 Parts of a Microscope

i) Structural Parts

Base: The base parts of microscope is the bottom part of the instrument and serves as a support for the rest of the microscope. It typically has a sturdy, heavy construction to help keep the microscope stable when in use.

Arm: The arm of the microscope is the long, curved structure that connects the base to the rest of the microscope. It provides support and stability to the microscope, as well as allowing the user to easily move the microscope around.

Head: The head of the microscope is the part that contains the eyepieces and objective lenses. It is typically mounted on the arm of the microscope, and allows the user to adjust the focus and magnification of the microscope.

ii) Optical Parts

Eyepieces: The eyepieces parts of microscope are the lenses that the user looks through to view the specimen. They are typically located on the head of the microscope and can be adjusted to achieve the desired magnification.

Eyepiece Tube: The eyepiece tube parts of microscope is the part of the microscope that holds the eyepieces. It is typically located on the head of the microscope and is the part of the microscope that the user looks through to view the specimen. The eyepiece tube is usually a tube-like structure that is mounted on the head of the microscope and contains one or more eyepieces.

Objective lenses: The objective lenses of the microscope are the lenses located below the stage that are used to magnify the image of the specimen. There are usually several objective lenses available, with different magnifications that can be switched out to achieve the desired level of magnification.

The nosepiece: The nosepiece, also known as the turret or revolving nosepiece, is a rotatable part of a microscope that holds the objective lenses. It is typically located below the stage and allows the user to easily switch between different objective lenses to achieve the desired magnification.

Coarse focus knob: The coarse focus knob is used to make large adjustments to the focus of the microscope. It is typically located on the base of the microscope and is used to bring the image of the specimen into rough focus.

Fine focus knob: The fine focus knob is used to make small adjustments to the focus of the microscope. It is typically located on the base of the microscope near the coarse focus knob and is used to fine-tune the focus of the specimen.

The Stage: The stage parts of microscope is a flat platform located below the head of the microscope. It is used to hold the specimen being viewed and can be moved horizontally or vertically to adjust the focus and positioning of the specimen.

Stage clips: The stage clips are used to hold the specimen in place on the stage of the microscope. They are typically located on the sides of the stage and can be adjusted to hold the specimen securely in place.

Stage controls: The stage controls are used to move the stage of the microscope horizontally or vertically. They are typically located on the base of the microscope and allow the user to position the specimen in the field of view.

Condenser: The condenser is a lens system located below the stage that is used to focus light onto the specimen. It is typically adjusted using a knob or lever and is used to fine-tune the lighting of the specimen.

An Aperture: An aperture in a microscope is a small opening that controls the amount of light that passes through the microscope. There are several apertures on a microscope, including: Diaphragm, Iris diaphragm, Field diaphragm.

Illuminator: The illuminator is a light source used to illuminate the specimen being viewed in a microscope. It is typically located below the stage and is an essential part of the microscope as it provides the necessary lighting for the microscope to function properly. There are several types of illuminators used in microscopes, including: Incandescent bulb, Fluorescent bulb, LED, Halogen.

The condenser: The condenser is a lens system located below the stage of a microscope that is used to focus light onto the specimen being viewed. It is an important part of the microscope as it helps to provide the proper lighting of the specimen, which is essential for achieving a clear and detailed image.

Diaphragm: The diaphragm is a small, adjustable aperture located below the stage that is used to control the amount of light that reaches the specimen. It is typically adjusted using a knob or lever and is used to fine-tune the lighting of the specimen.

Condenser focus: The condenser focus knob is a knob located on the base of a microscope that is used to adjust the focus of the condenser. The condenser focus knob is an important part of the microscope and is used to fine-tune the lighting of the specimen.

Abbe condenser: The Abbe condenser is a type of condenser that is used in microscopes to focus light onto the specimen being viewed. Some microscopes may have an adjustable diaphragm located in the light path of the Abbe condenser, which allows the user to control the amount of light that reaches the specimen.

Functions of Microscope

Magnification: The primary function of a microscope is to magnify the image of a specimen so that it can be viewed more clearly. Microscopes use lenses to magnify the image and can achieve very high levels of magnification, allowing the user to see details that are not visible to the naked eye.

Illumination: The microscope also includes a light source, known as an illuminator, which is used to illuminate the specimen being viewed. The illuminator is an essential part of the microscope as it provides the necessary lighting for the microscope to function properly.

Focus: The microscope allows the user to adjust the focus of the image by moving the objective lenses and eyepieces. This allows the user to bring the image of the specimen into focus and see it more clearly.

Observation: The microscope allows the user to observe and study the specimen in detail. It can be used for a wide range of applications, including scientific research, medical diagnosis, and industrial inspection.

Analysis: The microscope can also be used to analyze the specimen, such as by measuring its size or identifying its structure and composition. This can be done using specialized techniques, such as staining or fluorescence microscopy.
