| Popis | In this paper an imaging spectroscopic reflectometer with enhanced spatial resolution is presented. Main features of its design, experimental data acquisition, i.e. maps of thin film spectral dependencies of local reflectance and the local thickness map determination are described. The ability of this instrument to characterize thin film thickness non-uniformity with high gradients is demonstrated on measurements of thin film edges. A comparison with an older device is also presented. |
