| Research Abstract |
An MgF_2 aspheric corrector for a VUV Schmidt camera was manufactured using high-accuracy grinding. The quality of the finished surfaces was evaluated by optical interferometry, and it was confirmed that a surface accuracy ofλ/3 PV(peak-to-valley)@ 135.6 nm was achieved. A surface accuracy of? E/4 can be expected by combination of the high-accuracy grinding and magneto-rheological finishing. The surface roughness ofλ/100 obtained for this test piece is good enough for practical application.
