Resolving power refers to the clarity with which an objective can clearly separate two points or lines lying close together. The shorter the distance between the points or lines, the greater the resolving power. Also the higher the N.A. (numerical aperture) number of the objective, the greater it’s resolving power. Resolution is the ability to distinguish two points as two points. One may need to compromise between resolving power and resolution to achieve the desired image.
