Optical profilometry of cylindrical openings for transparent objects

WebAlthough optical techniques are inherently diffraction-limited, ellipsometry exploits phase information (polarization state), and can achieve sub-nanometer resolution. In its simplest form, the technique is applicable to thin films with thickness of less than a nanometer to several micrometers. WebIn optical profilometers, the wavelength of the light determines the limit of resolution. Fine structures below a micron are hardly to detect. Using an AFM, you see structures in the nm-range. So...
