ACS Nano—, This behavior can be understood intuitively. Driven by the rapid advancement of technology in the last few years, fiber coupled THz TDS systems have gained in robustness, flexibility and reliability to suit the demands of an industrial environment. The custom-built TDS system at Oxford is well-suited for determining the dielectric function at different temperatures as the cryostat and THz optics are enclosed in the same vacuum space, avoiding the need for cryostat windows. In the offline measurements we have confirmed the general idea of higher absorption coefficient and refractive index for harder rubber and quantified the results for various samples provided by ContiTech AG. An X-ray study of the temperature dependence of the quartz structure.

    Knowledge of the complex refractive index of quartz is required for analysis of time-domain terahertz spectroscopy and optical pump terahertz probe spectroscopy for samples on a quartz substrate. In conclusion, our offline THz—TDS measurements show that it is possible to distinguish rubber with different hardness by their refractive index and by their absorption coefficient.
