A microscope is a scientific instrument that allows us to magnify and observe objects that are too small to be seen with the naked eye. It has several parts that work together to create an image of the sample being viewed.

The first part of a microscope is the objective lens, which is the lens closest to the sample. There are usually several objective lenses of different magnification levels, ranging from low to high. The objective lens is responsible for gathering light and forming an image of the sample.

The next part is the stage, which is a flat platform where the sample is placed. The stage is usually adjustable, allowing the user to move the sample in different directions to get a better view.

Above the stage is the condenser, which is a lens that focuses light onto the sample. The condenser helps to brighten the image and increase contrast.

The eyepiece, also known as the ocular lens, is located at the top of the microscope and is used to view the image. The eyepiece typically has a magnification of 10x.

The diaphragm, located below the stage, is an adjustable aperture that controls the amount of light that passes through the sample. By adjusting the diaphragm, the user can fine-tune the lighting conditions to get the best image possible.

Finally, there is the base, which is the bottom part of the microscope and provides stability and support. The base also houses the illumination source, which is typically a light bulb or LED.

In addition to these main parts, there are also various other components that may be present on a microscope, depending on the model and its intended use. These can include a mechanical stage for precise movement of the sample, a pointer for indicating specific areas on the sample, and filters for adjusting the color of the light.

Overall, the various parts of a microscope work together to allow us to view and study objects that are too small to be seen with the naked eye, providing a crucial tool for scientific research and discovery.

A microscope stand composed of a base with a single vertical pole or post. Magnification power is the product of eyepiece lens power and objective lens power. As an example, human body parts such as organs and other tissues are made of cells that can only be seen or studied using a microscope. Essentially, Barlow lenses are auxiliary lenses that can be used to increase or decrease the total magnification by a given factor. The base will have a stand and may have a clamp for securing a microscope to a desk.

The upper part of the microscope also called the Body that includes the eyepiece tubes and prisms. From how to use them, to how to maintain and choose one for your intended purpose. Fine Focus A knob used to fine tune the focus of a specimen in conjunction with the coarse focus. Pole Stand : A microscope stand composed of a base with a single vertical pole or post. Its found at the top of the microscope.

Once the unit has been turned on, then the next step involves turning or switching on the incident or transmitted illumination or both depending on the specimen. This is particularly used to view cell structures, like a nucleus, which are otherwise invisible in bright field microscopy. Ans:Compound microscope also called student microscope is the most common microscope used in laboratories. Compared to a compound microscope where the objectives attached to the nosepiece can be seen and identified individually based on color bands and their respective labels , the objectives of a dissecting microscope are located in a cylindrical cone and are therefore not directly seen. The light transmitted from the specimen enters the objective lens.

Arm Arm is a structural part of the microscope that connects the head tube with the base of the microscope. Microscopy is the use of microscopes to examine things that are too tiny to see with the naked eye. A focusing system with both the coarse and fine focusing knobs mounted on the same axis. An alternative description for a nosepiece. This allows the slide to be easily inserted or removed from the microscope.

They play a major role in ensuring clear sharp images are produced with a high magnification of 400X and above. Auxiliary lens Source: Amazon: In addition to the objective lenses, some dissecting microscopes can accept accessories like Barlow lenses. One knob moves the slide left and right, the other moves it forward and backward. Fine Adjustment Knob Fine Adjustment Knob is used for fine adjustment. A standard adapter for mounting 35mm cameras to microscopes.

It also carries microscopic illuminators. Stage : The flat platform that supports the slides. They truly are a remarkable feat of human engineering and scientific discovery and yet there is so much more to know! There are different types of microscopes like a light microscope, dark-field microscope, phase contrast microscope, electron microscope, fluorescent microscope, etc. The glass plate is usually held in place by a tight screw located at the central, front part of the base. Also, focus slowly to avoid contact between the objective and the specimen. Subcellular structures are also explored using various types of microscopes.

Doublet Lens : A lens with two different lenses "welded" together. A microscope is typically composed of a head or body and a base. This feature is particularly common at the front part of a rigid arm. Polarizer — Used with an analyser to produce a polarized image. At AmScope , we pride ourselves on providing the best instruments at the lowest prices without sacrificing customer service. Light passing through such a specimen is absorbed. This part is where doctors or scientists put the microscope slide with samples for analysis; it normally has clips that prevents a slide from moving while it is being viewed by the user from the eyepiece part; the slide can be moved manually while it is being viewed or it can be moved mechanically if you are using a microscope with a mechanical platform; this is done by rotating the knobs which can either move the slide sideways or upward and downward.

It is used from observing simple unicellular organisms, various biological tissues to very high-resolution subcellular structures. A typical microscope contains the following parts; 1. Course Focusing Knob We use it to adjust the position of objective lenses. Aperture is the hole in the stage through which the base transmitted light reaches the stage. It is located below the stage, just above the illuminator. The part of the microscope that connects the eyepiece tube to the base.
