Unique Optical Reverse Engineering to determine materials optical properties

  • Uniquely determined unknown film properties among the film stack from the ellipsometry (SE) + transmittance ( Ta ) +  film side reflectance (Ra)  +glass side reflectance (BRa) 

  • Uniquely accurate to predict the optical film stack performance (The spectra meet with the simulations very well)​​
