In the present paper, a new inversion method of optical constants of semitransparent materials was introduced based on transmittance spectrograms of double slabs of semitransparent materials, and validation of the new inversion method was investigated.
Conclusions (1) The new inversion method based on transmittances of double slabs in this paper combined with experiment can acquire the optical constants of solid materials
