| Research Abstract |
A new ultra-precision profiler has been developed in order to measure such as asymmetric and aspheric profiles. In the present study, the normal vectors at each points on the surface are determined by the reflected light beam goes back exactly on the same path as the incident beam. The surface gradients at each point are calculated from the normal vector and the surface profile is obtained by integrating the gradient. The measuring instrument was designed according to the above principle of the measuring method. In the design, four ultra-precision goniometers were applied to the adjustment of the light axis for the normal vector measurement. The angle positioning resolution and accuracy of each goniometer are respectively 0.018μrad and 0.2μrad. In the measuring instrument, the most important item is the measuring accuracy of the normal vectors by the goniometers. Therefore, the rotating angle positioning errors were measured and calibrated. A SiC flat mirror 25.4mm in diameter and an elliptical profile mirror for nanometer hard X-ray focusing were measured. and compared to the measured profile using a Zygo Mark IVxp phase-measuring interferometer. The absolute measurement accuracy of approximately 5 nm (peak-to-valley) was achieved. Then the measurement of a spherical shape and 460mm, 1m long plane mirrors were demonstrated.
