WebP-V and RMS are both calculated from the same data, such as an interferometer measurement, but the meanings are quite different. P-V Is the difference in height between the highest and lowest points on the surface. P-V is good at giving a “worst-case-scenario” for the surface. RMS is a method for describing the average deviation of the ... WebMar 10, 2006 · In the low-k 1 lithography age such as today, reducing wavefront aberrations of projection optics is of crucial importance. Whereas the NA of an exposure tool becomes close to 1.0 or more, its residual aberration has attained 10 milli-lambda or less.
