Nalux has developed a unique 3D nanometric fabrication technology in several years. Unlike conventional diamond turning machines that are restricted to symmetric components, this device is capable of cutting any free-form surface which can be specified by a xyz coordinate map. This 3D nanometric fabrication technology includes CAD/CAM, ultra-precision machining using single crystal diamond, and high precise shape evaluation. The capabilities of the technology are demonstrated in this paper. We have succeeded in fabricating two unique optical components used in an adaptive optics system at the Subaru 8.2 m Telescope of National Astronomical Observatory of Japan. The first component is a microlens array that is used in the wavefront curvature sensor. This 37- element array has the individual lens elements distributed in a nonrectangular pie pattern, with very tight tolerances on focal point, focal length, lens shape, and the radius of each lens. The second component is an atmospheric phase plate that generates the atmospheric phase aberrations. This component requires a prescribed random surface yet requires a high degree of smoothness. This component is used to test adaptive optic systems.
