[QUOTE="AaronBurr, post: 4992280, member: 540730"] [B]Thank you all for any help or advice you can give. 1. Homework Statement [/B] What is the fabrication Wavefront error (WFE) of a mirror with a PV surface error of 1 um? Express your answer in terms of RMS waves at lambda = 0.633 um [h2]Homework Equations[/h2] WFE=2*SFE [h2]The Attempt at a Solution[/h2] I know to start by calculating the WFE. I know the SFE=1um WFE=2*1um WFE=2um PV I don't know how to convert PV into RMS. Everything I've read says there is no set ratio between PV and RMS measurements. But that values from 3-5 are commonly used depending on the surface error. So I'm a little confused. Thank you again for any help you can offer. [/QUOTE]
