WebPeak-to-Valley (PV) and Root-Mean-Square (RMS) are two common parameters used to measure the difference between an ideal optic surface to the actual optic surface. Historically the PV is used more often than RMS but RMS is a much better method for measuring the feat of an optic. WebAberration function, as the term implies, describes the size of aberration as a function of its determining factors. Since aberrations result from the interaction of light with optical surface, these determining factors belong to these three main groups: (1) properties of light falling onto optical surface, (2) properties of the surface, and.

The peak to valley ratio is another way to assess the effective separation; that is, how far does the valley go below the smaller peak. A larger ratio implies a better separation.
