The Word "HPO" in Microscope stands for High Power Objective.
Most standard compound microscopes use a combination of an eye piece lens and objective lenses in order to magnify an object. In the majority of these microscopes, the eye piece lens will have a magnification factor of 10 x, or ten times the original size, and the objective lens system will consist of three lenses of varying focal lengths, described as low, medium and high power objective lenses.
The magnification factors (MF) of the three objective lenses are usually as follows:
- Low Power Objective (LPO) Lens, MF = 4 x
- Medium Power Objective (MPO) Lens, MF = 10 x
- High Power Objective (HPO) Lens, MF = 40 x
The total magnification possible with a standard compound microscope is the multiple of the magnification factor of the eye piece lens and the objective lens in use. In other words, total magnification using the LPO lens would be 40 times the original size, the MPO lens would achieve a total magnification of 100 times, while the HPO lens will achieve a total magnification of 400 times the original size of the object to be viewed.
The HPO lens is longer, and therefore closer to to the object viewed, resulting in a narrower field of vision, making it difficult to study living, fast moving organisms. It does, however, make it possible to see details which are not visible on lower magnification on non-living specimens or slow moving living organisms. The HPO lens allows users to zoom in on specific areas of an object to be viewed and identify details not visible on lower magnifications.
The function of the HPO lens on a microscope is therefore to provide maximum possible magnification in order to view and identify details which can not be discerned while viewing the object through an objective lens with a lower magnification factor.

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.
How do you know which is lpo or hpo by just looking objective?
When talking about the IPO and HPO, it is referring the magnification of a microscope. You can tell the difference of the two, because the LPO is shorter than the HPO.
How do you know which is LPO HPO of a microscope?
The LPO will be shorter than HPO lens. LPO= magnifies 10x lenses HPO= magnifies 43x lenses
Where is the light brighter at the LPO or HPO?
The light is typically brighter at the High Power Objective (HPO) compared to the Low Power Objective (LPO) in a microscope. This is because the HPO has a narrower field of view and higher magnification, allowing more light to be focused on a smaller area. However, the increased brightness at HPO may also depend on the microscope's illumination settings and the quality of the objectives used.
What does HPO in HPO axis mean?
H-P-O Axis means Hypothalamus-Pitutary-Ovarian Axis, which is the basic function for mensuration cycle in women
Which part of the microscope will you adjust if the onion cell you are observing under the HPO is not clear?
You should adjust the fine focus knob to sharpen the image when viewing the onion cell under high-power objective (HPO) on a microscope. Rotate the knob gently to focus the specimen until the image appears clear.
What does letter a looks in microscope under hpo?
Under a high-power microscope (HPO), the letter "a" would appear as a magnified image with greater detail of its structure. You may be able to see the individual fibers or pixels that make up the letter, as well as any imperfections or irregularities in the ink or paper.
What is the magnification of the specimen under lpo and hpo?
The magnification of the specimen under low power optics, lpo, is 10 times and the magnification of the specimen under high power optics, hpo, depends on the power of the microscope but is usually at least 500 times or more.
