Metallurgists use this method to examine the microstructure of polished metal alloys, revealing grain boundaries, inclusions, and phase distributions that determine material strength. By bridging this gap optically, the oil prevents the loss of photons through reflection and allows a much larger cone of light to enter the objective, which is the physical definition of numerical aperture.

The high resolution provided by the oil ensures that minute imperfections which could lead to product failure are detected before the components proceed to assembly. The ability to see subtle variations in cell shape, arrangement, and internal structures directly impacts the speed and accuracy of identifying infectious agents.
The oil objective is then lowered into the oil drop, ensuring contact without crashing into the slide. After observation, the oil must be meticulously cleaned using a laboratory wipe followed by a pure solvent like ethanol to prevent residue from hardening on the lens surface.

4 times, allowing the viewer to distinguish details as small as 0. Furthermore, the depth of field is extremely shallow at these high magnifications, meaning that only a very thin plane of the specimen remains in focus at any given time.
