What iis the advantage of lpo and hpo disanvantage?

The advantage of LPO (Low Power Objective) is that it provides increased magnification and resolution for viewing smaller details on a specimen. The disadvantage is that it has a smaller field of view and less depth of field compared to lower magnification objectives.

The advantage of HPO (High Power Objective) is that it offers even higher magnification for detailed examination of specimens. The disadvantage is that it has a very narrow depth of field, making it challenging to focus on thicker specimens or to view multiple layers simultaneously.
