Magnification is the process of visually enlarging an object, but not physically. In many instances, it’s confused with “resolution,” which describes an imaging system’s ability to come up with a detailed display of the object that’s being imaged.

On the other hand, the distance between two distinguishable radiating points determines resolution. A microscopic imaging system may consist of numerous individual components, such as a lens, recording, and display components. Each of these factors, including the environment where the imaging is conducted, contributes to the system’s optical resolution. Optical systems are complex, and practical constraints often increase the distance between visible point sources.

While high magnification without high resolution may enable observers to view tiny microbes, it won’t allow them to identify between microbes or their sub-cellular sections. Therefore, it’s safe to say that microbiologists rely more on resolution because they want to distinguish between microbes and their subsections. However, to differentiate between two objects under a microscope, they must first magnify up to a point wherein resolution becomes relevant.

So, which of the two is more important? Magnification and resolution are two entirely different things. Although this is the case, they have an interdependent relationship.
Magnification is usually critical in scientific research, but only if the resolution is sufficient enough to see all of the fine detail in question.

Therefore, scientists need both magnification and resolution. Having the best resolution and precise magnification is always ideal for capturing the most incredible images possible.
