What is the advantage of using high power objective on a microscope?
The advantage of a high power objective lens is that it provides a higher degree of magnification, which allows you to “zoom” in closer to the object being studied and see more detail. However, a lower power lens will provide a wider field of vision. This is analogous to using a magnifying glass to examine an insect.

What is HPO and LPO in microscope?
When you change from low power to high power on a microscope, the high-power objective lens moves directly over the specimen, and the low-power objective lens rotates away from the specimen.
What does high power on a microscope mean?
High power microscopes – also called compound microscopes because of their two-stage magnification – are the ‘typical’ microscope that is seen in laboratories and on television. High power microscopes typically magnify in the range ×40 to ×1000; much greater than this will only produce fuzzy images with no more detail.
What is the role of high power objective?
A high-power objective lens magnifies 40x, with total magnification 400x if the eyepiece lens is 10x power, and it is ideal for observing very fine detail, such as nerve cells in the retina or the striations in skeletal muscle. The longest objective lens is an oil immersion objective lens, which magnifies 100x.
What are the advantages and disadvantages of using the high power objective?
The advantage of using an objective with higher magnification is an increase in detail can be viewed. The disadvantage of viewing at a higher magnification is that less of the slide can be viewed.
What is a high power objective lens?
The high-powered objective lens (also called “high dry” lens) is ideal for observing fine details within a specimen sample. The total magnification of a high-power objective lens combined with a 10x eyepiece is equal to 400x magnification, giving you a very detailed picture of the specimen in your slide.
What is the difference between low and high power microscope?
The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced. Therefore a smaller part of the specimen is in focus at higher power. The amount of light transmitted to your eye is greatest at the low power.

What is the magnification of the high power lens?
400x
| Magnification | Total Magnification | |
|---|---|---|
| Scanning | 4x | 40x |
| Low Power | 10x | 100x |
| High Power | 40x | 400x |
| Oil Immersion | 100x | 1000x |
What is low and high power objectives?
The compound microscope may contain one or two other lenses called objective lenses. If there are two objective lenses, they are called the low-power and high-power objective lenses. The low-power objective lens usually magnifies 10 . The high-power objective lens usually magnifies 40 .
What is the objective magnification of the high power lens?
What is special about the 100x objective lens?
The most powerful lens of the light microscope is the 100x oil immersion objective. Because light is refracted every time it passes through a medium with a different refractive index, (air to glass or vice versa) the quality of the image is reduced with each passage.
What can you see with a 40x microscope?
5mm
Field of view is how much of your specimen or object you will be able to see through the microscope. At 40x magnification you will be able to see 5mm.
