We can design an immersed polarizing beamsplitter operating in the spectral range from 400 to 700 nm for AOI of 65-75 degrees. Refractive index of the corresponding prism is 1.85.

These design specifications were taken from Li Li and J.A. Dobrowolski, "New developments in thin film polarizing beamsplitters", in Optical Interference Coatings, Vol. 9, OSA Technical Digest Series, (Optical Society of America, Washington DC, 1998), pp. 158-160.

Target specifications:

  • Ts[%] > 99.9% for wavelengths 400-700 nm at AOI from 65 to 75 degrees
  • Tp[Optical Density] > 3.0 for wavelengths 400-700 nm at AOI from 65 to 75 degrees
