resolving power

 
the ability of the eye or of a lens to make small objects that are close together separately visible, thus revealing the structure of an object.

re·solv·ing pow·'er

1. definition of a lens; in a microscope objective lens it is calculated by dividing the wavelength of the light used by twice the numeric aperture of the objective.
See also: definition.
2. analogies to other modalities, for example, two-point discrimination in neurologic examination. Commonly misinterpreted as random error, although it has none of its properties.
3. Synonym(s): resolution (2)

[rizol′ving]
1 the ability to separate closely migrating substances, as in electrophoresis.
2 the ability to distinguish closely positioned objects as distinct entities.

resolving power

In mass spectrometry, the ability of a spectrometer to distinguish between ions that differ only slightly in their m/z ratios.
