Angstrom Sun Technologies Inc is glad to introduce education version TFProbe eSE for Universities, start-ups and R&D users. It is affordable and true spectroscopic tool. It comes with advanced TFProbe 3.3 software for system configuration, data acquisition, simulation and regression. Different user log-in level allows Scientists/Engineers to play complicated layer stacks, isotropic/anisotropic, super-lattice, inhomogeneous with various index profile builder, while operator mode provides one-button click to have results, plus lifetime software upgrade without cost and professional application support....
