Specifications subject to change without notice.
1 Retrace Error is defined as the residual error between a no tilt fringe (null) measurement (the reference), subtracted from a measurement with maximum fringes of tilt, with only the first 36 Zemike polynomials reported
2 RMS Simple Repeatability as defined as 2X the standard deviation of the RMS for 36 sequential measurements (0 averages) of a short plano cavity
3 RMS Wavefront Repeatability is defined as the mean RMS difference between a synthetic reference (defined as the average of all 36 sequential measurements) and each measurement plus 2X the standard deviation
