All series of primary mirrors for RC are processed at least 1/18 PTV -1/60 RMS. So we get a value of the entire focal plane of at least 1/5-1/6 lambda 1/40 RMS.
Each optic is supplied with test report.
Each secondary mirror is tested by interferometric test at 660nm
and finally in autocollimation with a flat reference.
