A low power objective is essential on any microscope, It allows you to quickly scan a large area of the specimen, and to locate those areas which need closer study with a high power objective. For example, a histologic section of liver might measure 20 by 40 mm. With a 4x objective you can scan the entire piece of tissue in a minute or less. If there is a 1 mm tumor somewhere in the section, you will find it during this scan, and can them zoom in on it with the high power objectives. Trying to scan the entire slide with a 40x objective would take a long time because in any given field you can see only 1/100 the surface area included in a 4x scan), and you could easily miss a 1 mm tumor entirely. but this didnt helpso hanks aot for nothing
High power objectives provide high magnification for detailed observation of small structures, while low power objectives offer a wider field of view for locating specimens and getting a general overview of the sample. Switching between high and low power objectives allows for both detailed examination and context within a specimen.
They are kind of like zooms. The higher the power the closer you can see, the lower the power the farther out you can see. There are different size powers though. Most ofter the more expensive the microscope the higher and/or more powers it has.
The lowest magnification power is x4 (Eyepiece Lens) times x10 (Objective Lens) = x40 Magnification.

When changing objectives from low power to high power what is it necessary to do?
When changing objectives from low power to high power on a microscope, it is necessary to first ensure the current objective is retracted, then rotate the nosepiece to position the desired high power objective in place. Refocusing will also be required due to the change in magnification levels.
What power of the microscope used for endoplasmic reticulum?
A high-power microscope, such as an electron microscope, is used to visualize the endoplasmic reticulum. The intricate structure of the endoplasmic reticulum requires high magnification and resolution to observe its details effectively.
What are the dangers of high power objective?
Using high power objectives can lead to decreased depth of field, making it more difficult to keep the specimen in focus. Additionally, high power objectives are more sensitive to vibrations and movements, which can result in blurry images. Finally, using high power objectives increases the risk of damaging both the objective lens and the specimen due to the close proximity between them.
How can you tell by just looking at them which is the low power objective or high power objective?
The low power objective typically has a lower magnification level (e.g., 4x or 10x) compared to the high power objective (e.g., 40x or 100x), and it usually has a wider field of view. The high power objective will provide a closer magnified view of the specimen but with a narrower field of view. You can often find the magnification level labeled on the side of the objectives.
When you change from medium to high power what part of the microscope are you not suppose to touch?
When changing from medium to high power on a microscope, you should not touch the coarse focus knob. This knob is used to adjust the focus at lower magnifications and can cause the objective lens to crash into the slide if used at high power, potentially damaging the slide or the lens.
What is high power objectives in microscope?
The high-power objective on a microscope is larger lens with higher magnifying power. (40x)
What is a high power objective in a microscope?
A high power objective in a microscope is a lens that provides high magnification of the specimen being viewed. It typically magnifies the image by 40x to 100x, allowing for detailed observation of fine structures. High power objectives are used for examining smaller details and are typically used after lower magnification objectives.
How many objectives does a microscope have?
A microscope typically has three main objectives: low-power, high-power, and oil-immersion objectives. Each objective lens magnifies the specimen at a different level, allowing for a range of magnification options.
What are low and high power objectives?
Low power objectives on a microscope typically have magnification levels of 4x or 10x and are used for locating and centering the specimen. High power objectives, on the other hand, have magnifications ranging from 40x to 100x and are used for detailed examination of the specimen.
What are the 3 microscope objective and their power?
The three main microscope objectives are scanning (4x), low power (10x), and high power (40x). These objectives provide different levels of magnification for observing samples at varying levels of detail.
How many objectives does your microscope have what are they called?
A typical microscope has two main objectives: the low-power objective and the high-power objective. The low-power objective provides a wider field of view at lower magnification, while the high-power objective allows for closer inspection at higher magnification.
Which is longer the HPO or LPO in the microscope?
The HPO (high-power objective) has a higher magnification than the LPO (low-power objective) in a microscope. This means that the HPO will show a smaller area but with more detail compared to the LPO.
Why do you think a microscope always must be stored with the low power objective in place over the stage?
Storing a microscope with the low power objective in place helps to protect the more delicate high power objectives from damage. The low power objective serves as a barrier, preventing the higher power objectives from being accidentally touched or bumped during storage, which can affect their alignment and performance.
What do low and high power objectives do?
the difference between the low power and high power objectives on a microscope are that the low power objective has a lesser magnification than the high power objective
What is the objectives of use a microscope?
The objectives are what magnify an item. They are usually 10x, 40x, and 100x. These are also known as low power, high-dry, and oil immersion. Some microscopes also have a 4x for quick scanning.

When changing objectives from low power to high power what is it necessary to do?
When changing objectives from low power to high power on a microscope, it is necessary to first ensure the current objective is retracted, then rotate the nosepiece to position the desired high power objective in place. Refocusing will also be required due to the change in magnification levels.
