The high power objective on a microscope is used anytime you need to achieve greater detail and magnification, and is often used when identifying cells.
The high power objective is generally not used in teaching/learning labs as it is usually an oil immersion lens. Using oil means greater cleaning & care is required.
You do not use the coarse focus knob on high power because it can damage the slide and the objective lens of the microscope. Use only the fine focus knob to bring the specimen into sharp focus on high power.
The course-adjustment knob moves the stage up and down quickly, and using it with a high-power objective can potentially damage the objective or slide due to a rapid change in focus. It is best to use the fine-adjustment knob when using a high-power lens for precise focusing.
Using the coarse-adjustment knob with the high-power objective can result in the objective lens getting too close to the slide, potentially damaging the lens or slide. This can also lead to the objective lens hitting the slide, causing a loss of focus and potential damage to both the lens and the slide.
You can estimate the size of the object by comparing the field diameters observed under the low power objective lens (4x) and high power objective lens (40x). Calculate the ratio of the field diameters (40x/4x = 10), and use this ratio to estimate the size of the object viewed under the high power objective lens. Simply multiply the size of the object viewed under the low power objective lens by the ratio (field diameter at 4x) to get an estimation.
Using the course adjustment knob on high power can cause the microscope to move too quickly, potentially damaging the specimen or the objective lens. It is better to use the fine adjustment knob on high power for precise focusing.
The high-power objective magnifies the image 4x.
The high power objective on a compound microscope typically has a magnifying power of 40x or 50x.
The high power objective increases the magnification of the specimen (it contributes to a further magnification). It magnify specimens at greater resolutions, which allows you to see fine details.

The longest objective that is usually used the least. The opposite of a low power objective.

So you do not crack the high power objective lens - this lens is very fragile and expensive.

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.
