Labelled Microscope Parts

A high-power microscope called a compound microscope has magnification capabilities that are higher than those of a low-power or dissection microscope. It is used to look at minute specimens like cell structures that are not visible at lower magnification levels. Both structural and optical elements are present in a compound microscope. The head, arm, and base are the three structural parts of a compound microscope.

Structural Components

1. Head: The optical components found in the upper portion of the microscope are found in the body or head.
2. Arm: The function is connecting and supporting the microscope’s base and head. The microscope is also transported using the arm.
3. Base: The base of the microscope holds the illuminator and serves as a support for the instrument.

Optical Components

1. Eyepiece: The upper part of the microscope contains the ocular, often known as the eyepiece, through which the observer views.
2. Eyepiece Tube: The eyepieces are held in place by the eyepiece tube, which is placed above the objective lens.
3. Objective Lenses: The primary optical lenses are the objective lenses. They have different magnifications ranging from 4x to 100x, and a single microscope often has 3 to 5 lenses.
4. Nosepiece: The objective lenses are kept in the nosepiece.
5. Adjustment Knobs: The adjustment knobs that are frequently used to focus the microscope are the fine and coarse focus knobs. The knobs are coaxial. This indicates that both the fine focus and coarse focus focusing systems are placed on the same axis. In order to adjust the lighting, there is also a condenser focus knob that raises or lowers the condenser.
6. Stage: The specimen that will be placed or presented is put up on the stage. When working on a specimen under increased magnification, a mechanical stage is frequently utilized. At this point, the specimen needs to be moved carefully.
7. Stage Clips: Slide placement is controlled by stage clips. The observer must manually move the slide in order to view various portions of the specimen. The mechanical stage has a separate knob that can be used to manipulate the slide.
8. Aperture: The aperture is a small opening in the stage through which transmitted light enters.
9. Illuminator: The light source, an illuminator, is usually found at the base of the microscope. The majority of light microscopes use low-voltage halogen lights and have base-mounted controls for both continuous and varied lighting.
10. Condenser: The light from the illuminator is normally collected and focused onto the specimen using a condenser. It is located below the stage and is frequently seen alongside an iris or a diaphragm.
11. Iris: The amount of light that reaches the specimen is controlled by either the iris or diaphragm. It can be found below the stage section but above the condenser.

A Microscope is an apparatus that enhances the views of tiny substances. It gives the viewer a remarkably close-up picture of minuscule structures at a scale suitable for scrutiny and study. Invisible to the human sight microscopic items are magnified using the microscope. Additionally, a microscope allows us to see a variety of species, such as a cell, the structure of dust particles, etc. It comes from the Greek words “mikros,” which means small, and “skopein,” which means to see.
