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 power of a low power objective lens typically ranges from 4x to 10x. This lens is used for initial scanning and locating objects on the slide before moving to higher magnifications for more detailed observation. It provides a wider field of view compared to higher power objective lenses.
A low power objective is an essential function of a microscope, It allows a quick scan of a large area of the specimen.
the objective in between scan and high power.
you can see a pretty good range of things at a pretty good magnification
The standard simple microscope consists of 4x, 10x and x40 objective lenses.
Therefore the power of the lowest objective lens is x4.
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.
The three objective lenses on a compound microscope are typically labeled as low power (4x), medium power (10x), and high power (40x). Each lens has a specific magnification power that allows for viewing specimens at various levels of detail.
A low power objective in a microscope is a lens with a lower magnification typically ranging from 4x to 10x. It allows you to observe a larger area of the specimen at once with less detail than higher power objectives. Low power objectives are useful for locating and positioning the specimen before using higher magnification objectives.
