WebOptical filters will often include specifications for any or all of flatness, transmitted wavefront distortion or error (TWD/TWE), and reflected wavefront distortion or error (RWD/RWE), defined over the clear aperture of the filter or per unit of lateral dimension (e.g. per inch). In practice, specifying TWD and/or RWD should suffice. WebZernike fit, the underlying, low order, optical surface figure is captured. This represents the bulk of the surface amplitude. The table shows the relationship of detector resolution to PV and PVr for a 300 mm flat optic. It shows the effect of reducing pixel resolution computationally on PV and PVr.

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 ...
