The low power objective lens helps to first fine the specimen or object being viewed, and to focus the microscope. Once the lens power becomes higher it is much harder to focus the microscope and find the desired object of viewing.
The low power objective lens on a microscope is also known as the scanning lens.
The revolving nosepiece or turret rotates to change from the low power objective lens to the high power objective lens on a microscope. This component allows for easy switching between different objective lenses without the need to manually remove and insert them.
When viewing a specimen, you must always use the lower power objective lenses first. Low power lens gives the widest field of view and makes it easier to find the specimen when you look through the microscope. Finding the specimen at high power, without first centering it in the field of view at low power, is nearly impossible.

A low power objective in a microscope is a Small Lens with Low Magnifying Power. A microscope head with two eyepiece lenses, one for each eye. Generally this term is used in describing a high power (compound) microscope. With a low power microscope we say "stereo" head because, unlike the compound microscope, the stereo has a separate objective lens for each eyepiece lens, producing two independent paths of light, one for each eye. In the compound microscope with a binocular head, there are two eyepiece lenses but still only one objective lens and you will not get stereo vision. Hope this helps.

The low power objective is small lens with low magnifying power.
The low power objective lens is usually a 10x lens and it is used to orient the specimen and get it focused before switching to a higher power lens.
The low power objective lens on a microscope is also known as the scanning lens.

The eyepiece lens of a compound microscope acts essentially a low power (x10 or so) magnifier of the real image created by the objective lens.

The revolving nosepiece or turret rotates to change from the low power objective lens to the high power objective lens on a microscope. This component allows for easy switching between different objective lenses without the need to manually remove and insert them.
Total magnification with a low power objective lens is calculated by multiplying the magnification power of the objective lens by the magnification of the eyepiece (ocular lens). Typically, a low power objective lens has a magnification of 10x or 4x, and when combined with a standard 10x eyepiece, the total magnification would be 100x or 40x, respectively. Therefore, total magnification for low power objectives usually ranges from 40x to 100x.
Storing a microscope with the low power objective lens in place helps protect the lens and prevents accidental damage or contamination during storage. The low power lens is less delicate compared to other high-power lenses, making it a safer option for storage to ensure the microscope remains in good condition for future use.
The nosepiece of a microscope holds multiple objective lenses, each with different magnification levels that range from high to low power. Rotating the nosepiece allows you to switch between these objective lenses to adjust the magnification of your specimen.
