Abstract

In this paper, the new method on testing and evaluating of optical surface microprofile using Atomic Force Microscope (AFM), which has both good vertical and lateral resolution. The nanometer-grade microprofile of super-smooth optical surface can be obtained using AFM method, but can't by classical interferometer, as the latter has a poor lateral resolution. Some tested examples of optical surface are shown in the paper. The microprofile images are viewed in monitor and printed in microcomputer.
