TECHSPEC® Broadband Polarizing Cube Beamsplitters

  • Designed for VIS and NIR Wavelength Ranges
  • 500:1 Extinction Ratio
  • AR Coated for R<0.5% per Surface

Polarizing cube beamsplitters split randomly polarized beams into two orthogonal, linearly polarized components: S-polarized light is reflected at a 90° angle while P-polarized transmitted. Each beamsplitter consists of a pair of precision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse of one of the prisms. An antireflective coating has been applied to each face of the beamsplitter for reflection <0.5% per surface. Designed for broadband applications, these beamsplitters offer a transmission of >90% for P-polarized light and a reflection for S-Polarized light across entire design wavelength range. Design wavelength range is 420-680nm for VIS beamsplitters and 700-1100nm for NIR beamsplitters.
