A compound microscope is defined as. A microscope with a high resolution and uses two sets of lenses providing a 2-dimensional image of the sample. The term compound refers to the usage of more than one lens in the microscope. Also, the compound microscope is one of the types of optical microscopes. The other type of optical microscope is a ...

The high power lens should be very close to your slide when in proper focus. If you turn the coarse adjustment knob while on high power, the objective could easily break your slide.
Which activity might lead to damage of a microscope and specimen? using the course adjustment to focus the specimen under high power.
Answer: The objective lens is the second of the two lenses doing the actual magnifying in a compound microscope, so if it is not snapped into proper position, you won't see the proper image. ... The magnification of an objective lens will always be a whole number.Feb 28, 2021
COARSE ADJUSTMENT KNOB — A rapid control which allows for quick focusing by moving the objective lens or stage up and down. It is used for initial focusing.
The main reason you stain a specimen before putting it under the microscope is to get a better look at it, but staining does much more than simply highlight the outlines of cells. Some stains can penetrate cell walls and highlight cell components, and this can help scientists visualize metabolic processes.Apr 26, 2018

Iris Diaphragm controls the amount of light reaching the specimen. It is located above the condenser and below the stage. Most high quality microscopes include an Abbe condenser with an iris diaphragm.
Illuminator. is the light source for a microscope, typically located in the base of the microscope.Dec 20, 2021
Lenses - form the image objective lens - gathers light from the specimen eyepiece - transmits and magnifies the image from the objective lens to your eye nosepiece - rotating mount that holds many objective lenses tube - holds the eyepiece at the proper distance from the objective lens and blocks out stray light.
Diaphragm or Iris: The diaphragm or iris is located under the stage and is an apparatus that can be adjusted to vary the intensity, and size, of the cone of light that is projected through the slide.
Parts of the Microscope Coarse adjustment knob- Focuses the image under low power (usually the bigger knob) Fine adjustment knob-Sharpens the image under all powers (usually the smaller knob) Arm- supports the body tube and is used to carry the microscope.
The part of a light microscope that focuses light onto the specimen through the lens is called the condenser.

The depth of field of a microscope is defined as how deep the focus area is for the given values of magnification.

All of the parts of a microscope work together - The light from the illuminator passes through the aperture, through the slide, and through the objective lens, where the image of the specimen is magnified . The then magnified image continues up through the body tube of the microscope to the eyepiece, which further magnifies the image ...
On/off switch: This switch on the base of the microscope turns the illuminator off and on. Illumination: The light source for a microscope. Older microscopes used mirrors to reflect light from an external source up through the bottom of the stage; however, most microscopes now use a low-voltage bulb.
A standard microscope has three, four, or five objective lenses that range in power from 4X to 100X. When focusing the microscope, be careful that the objective lens doesn’t touch the slide, as it could break the slide and destroy the specimen. Specimen or slide: The specimen is the object being examined.
Nosepiece: A rotating turret that houses the objective lenses. The viewer spins the nosepiece to select different objective lenses. Objective lenses: One of the most important parts of a compound microscope, as they are the lenses closest to the specimen. A standard microscope has three, four, or five objective lenses that range in power ...
Diopter Adjustment: Useful as a means to change focus on one eyepiece so as to correct for any difference in vision between your two eyes. Body tube (Head): The body tube connects the eyepiece to the objective lenses. Arm: The arm connects the body tube to the base of the microscope.
Iris diaphragm: Adjusts the amount of light that reaches the specimen. Condenser: Gathers and focuses light from the illuminator onto the specimen being viewed. Base: The base supports the microscope and it’s where illuminator is located.
First, the purpose of a microscope is to magnify a small object or to magnify the fine details of a larger object in order to examine minute specimens ...
The ocular lens is also known as the eyepiece. The image of microscopic objects can be viewed through these lenses. There are four types of magnification that can take place in the ocular lens:
A magnified image of the object is obtained by the objective lens. This image is known as the real image. The eyepiece or the ocular lens then magnifies the real image more and is viewed as the virtual image. The compound microscope is also known as the bright-field microscope because the light passes directly through the light source to ...
There are two types of lenses that are used in the compound microscope: The objective lens is placed close to the object that needs to be examined. The eyepiece allows the image to be viewed. The eyepiece is also known as the ocular lens. The light is made to pass through the thin transparent object. A magnified image of the object is obtained by ...
Working Principle of Compound Microscope. A compound microscope is considered to be one of the standard microscopes that can be used for general purposes. The arrangement of the lens is such that it magnifies the objects from the complex system. There are two types of lenses that are used in the compound microscope: ...
The difference between simple and compound microscope is that a simple microscope uses only one lens while the compound microscope uses more than one lens.
This also means that the sample must be translucent enough so that the light passes through it and every eyepiece contains the same image. Whereas in a stereo microscope there are two objective lenses that are used for magnification.
Body Tube. The main purpose of the body tube is to hold the objective and ocular lenses at the two ends. The end where the ocular lens is present is known as the head while the end where the objective lens is placed is known as the nose piece. For the passage of light rays through the body tube, there is a pathway.
The primary principle used here is the principle of compounding or magnification. The magnification factor of the eyepiece multiplied with that of the objective lens. This principle produces a magnified image. First, the specimen must be focused under the low-resolution objective lens by coarse adjustment.
A compound microscope is a type of microscope that uses two sets of lenses to magnify the image under the microscope. It has an objective lens that has a resolution of 4x,10x, 40x, 100x, and an eyepiece of resolution of 10x. The usage of both lenses, compounds or magnifies the image of the object below the objective lens to achieve a resolution ...
This structure is called the nose piece. Body tube: It is the hollow tube at the upper arm, which has one end of the eyepiece lens, and another term has an objective lens. The body tube is altered using the adjustment knobs. Fine adjustment knob: It is a tiny knob that is used for focusing on the slide accurately.
Optical Parts: Eyepiece: It is the lens used on the upper part of the body tube. It usually has a resolution of 10x but can be of 5x or 15x. It is the lens through which the person views the specimens. Objective lens: It is the lens used on the lower part of the body tube. It is attached to the nose piece.
The dust on the lenses, mirror, and stage is cleaned so that a clear image of the specimen can be seen. The slide that is to be examined should be placed on the stage, and clips are put so that the slide does not move. The nose piece is adjusted below the object to be focused.
It is a U-shaped structure. Pillar: It is the stand that lies on the stage and is a perpendicular projection. Arm: The whole microscope is managed or carried by the curve-shaped structure called the arm. Stage: It is the rectangular structure that has a hole in the center that allows the light to pass through it.
Objective lens: It is the lens used on the lower part of the body tube. It is attached to the nose piece. Usually, three or four nose pieces are available, which contains the objective lens of different resolutions like 10x, 40x, 100x.
