Abstract

Off-axis conic aspheric mirrors are crucial components in some optical systems, such as three-mirror-anastigmatic telescopes (TMA). However, because of the swing limitation of lathe, off-axis aspheric mirrors are not easy to fabricate using a general-purpose diamond turning machine. This research demonstrates slow tool servo diamond turning process which allows fabricating off-axis conic aspheric mirrors on-axis. The figure error caused by tool centering error was studied on. An off-axis parabolic mirror was fabricated and actual machining data are discussed. The result proved that proposed approach is capable of fabricating copper off-axis parabolic mirror of 46mm diameter to a form accuracy of 0.736μm in PV error value.
