What is the function of nosepiece in microscope?
Nosepiece: This circular structure is where the different objective lenses are screwed in. To change the magnification power, simply rotate the turret. Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. The most common ones are 4X (shortest lens), 10X, 40X and 100X (longest lens).

How can a microscope be used to assess human health?
– A microscope may be used to assess human health by examining a sampling of the individual’s cells to determine their condition, because after all, cell’s make up life.
What is the function of mechanical parts of microscope?
Importance, Components & Effective Use. A mechanical stage of a microscope refers to the mechanism that has been mounted on the stage for holding and moving the microscope slide. It is an important part of the microscope that enhances the function of the stage.
How do you describe the development of microscope?
In the late 16th century several Dutch lens makers designed devices that magnified objects, but in 1609 Galileo Galilei perfected the first device known as a microscope. Dutch spectacle makers Zaccharias Janssen and Hans Lipperhey are noted as the first men to develop the concept of the compound microscope.

A microscope lets the user see the tiniest parts of our world: microbes, small structures within larger objects and even the molecules that are the building blocks of all matter. The ability to see otherwise invisible things enriches our lives on many levels.
What is the importance of microscope in the field of medicine?
1 Answer. The microscope is important to medical laboratory technology for many reasons. The microscope is used in Hematology to observe different types of blood cells, so that they can be counted and categorized, and checked for abnormalities.
How do we use microscope?
Look through the eyepiece (1) and move the focus knob until the image comes into focus. Adjust the condenser (7) and light intensity for the greatest amount of light. Move the microscope slide around until the sample is in the centre of the field of view (what you see).
What are the mechanical equipment?
Mechanical equipment means equipment, devices, and accessories, the use of which relates to water supply, drainage, heating, ventilating, air conditioning, and similar purposes. Mechanical equipment means all motor or human propelled wheeled equipment used for roofing work, except wheelbarrows and mopcarts.
What are the two function of the eyepiece?
Functions of eyepiece in the microscope: To further magnify the intermediate image so that specimen details can be observed. Focuses the light rays from the primary to form a sharp image on the retina of the eye.
What are mechanical parts?
Mechanical parts means operational parts on a vehicle that wear out over time or have a finite useful life or duration typically shorter than the life of the vehicle as a whole. Mechanical parts do not include external crash parts, wheels, paint, or windshields and other glass.
What are the mechanical parts of microscope?
(A) Mechanical Parts of a Compound Microscope
- Foot or base. It is a U-shaped structure and supports the entire weight of the compound microscope.
- Pillar. It is a vertical projection.
- Arm. The entire microscope is handled by a strong and curved structure known as the arm.
- Inclination joint.
- Nose piece.
What are the parts of microscope?
The three basic, structural components of a compound microscope are the head, base and arm.
- Head/Body houses the optical parts in the upper part of the microscope.
- Base of the microscope supports the microscope and houses the illuminator.
- Arm connects to the base and supports the microscope head.
What are the two types of microscope?
The Different Types of Microscopes Exploring the Top Four and More
- The Compound Light Microscope.
- The Stereo Microscope.
- The Digital Microscope.
- The USB Computer Microscope.
- The Pocket Microscope.

- The Scanning Probe Microscope (SPM)
- The Acoustic Microscope.
What is microscope and its function?
A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is.
What is the function of body tube in microscope?
The microscope body tube separates the objective and the eyepiece and assures continuous alignment of the optics. It is a standardized length, anthropometrically related to the distance between the height of a bench or tabletop (on which the microscope stands) and the position of the seated observer’s…
What is the function of microscope condenser?
On upright microscopes, the condenser is located beneath the stage and serves to gather wavefronts from the microscope light source and concentrate them into a cone of light that illuminates the specimen with uniform intensity over the entire viewfield.
What are the 3 objective lenses on a microscope?
Most compound microscopes come with interchangeable lenses known as objective lenses. Objective lenses come in various magnification powers, with the most common being 4x, 10x, 40x, and 100x, also known as scanning, low power, high power, and (typically) oil immersion objectives, respectively.
How do you read a microscope objective?
Microscope objective lenses will often have four numbers engraved on the barrel in a 2×2 array. The upper left number is the magnification factor of the objective. For example, 4x, 10x, 40x, and 100x. The upper right number is the numerical aperture of the objective.
What are the function of each part of microscope?
Microscope Parts & Specifications
- The Functions of a Microscope.
- Eyepiece Lens: the lens at the top that you look through, usually 10x or 15x power.
- Tube: Connects the eyepiece to the objective lenses.
- Arm: Supports the tube and connects it to the base.
- Base: The bottom of the microscope, used for support.

What are objective lenses on a microscope?
An objective lens is the most important optical unit that determines the basic performance/function of an optical microscope To provide an optical performance/function optimal for various needs and applications (i.e. the most important performance/function for an optical microscope), a wide variety of objective lenses …
Where are the objective lenses located on a microscope?
The objective lens of a microscope is the one at the bottom near the sample. At its simplest, it is a very high-powered magnifying glass, with very short focal length. This is brought very close to the specimen being examined so that the light from the specimen comes to a focus inside the microscope tube.
What are the objectives of microscope?
Objectives allow microscopes to provide magnified, real images and are, perhaps, the most complex component in a microscope system because of their multi-element design. Objectives are available with magnifications ranging from 2X – 200X.
