摘要: Apparatus for inspecting the surface of a sample includes a wide scanning interferometer, which is used to locate defects, or anomalies in the surface, and a narrow scanning interferometer, which is used to develop profiles of individual defects found by the narrow scanning interferometer. The sample may be driven in rotation about an axis, while the interferometers are independently moved radially to the axis.
