Fixed Ratio Cube Beamsplitters

  • Two right angle prisms cemented together with a partially reflecting surface on the internal (protected) face
  • Reflectance/Transmittance is 50 / 50 % with tolerance of +/-5% at designed wavelengths

All dielectric coatings of fixed ratio laser beamsplitters are optimized to be insensitive to split only s- or only p-polarization or only unpolarized light (R = (RS+RP)/2 and T = (TS+TP)/2) at designed wavelengths.
