Steps to reproduce

Transmissivity of TPH and KBr windows were collected by doing spectroscopy for different thicknesses of TPH. Absorption coefficient was calculated from measured transmissivity and applying the derived equation and linear regression method. Absorptive index was calculated from absorption coefficient by their relation. Refractive index was extracted using measured refractive index of TPH at wavelength of 0.589 microns and applying Kramers-Kronig transform.
