Webb20 jan. 2011 · Posted 30 May 2024 - 06:08 PM. Zygo makes fast transmission spheres. You need an f/1 test beam to test at ROC if it is indeed f/0.5. If you don't have access to that, about all you can do is test it in sections. I'd have to do the same - the fastest diverger that I creates an f/1.7 test beam, which would cover just over half of that mirror. WebbAt the very beginning, Maksutov hoped Pan to get some useful findings from evaluating the Hindle test with a lot of calculations. After reading the publications of Maksutov, Pan found that Maksutov's compensation method for the control of primary mirrors of large telescopes was also suitable for the test of the secondary mirror, and this kind of method was …
