Product Family Description

  • Low Polarization Dependence: |Ts-Tp|<6%
  • Constructed from High Tolerance Right Angle Prisms
  • BBAR Coated Faces for Maximum Efficiency
  • C-Mounted Visible and NIR Cube Beamsplitters Also Available

TECHSPEC® Broadband Non-Polarizing Cube Beamsplitters consist of a pair of precision high tolerance right angle prisms cemented together with a metallic dielectric coating on the hypotenuse of one of the prisms. The low polarization dependence of the metallic dielectric hybrid coating allows the transmission and reflection of S- and P-polarization states to be within 6% of each other. These beamsplitters are spectrally flat across their specified wavelength ranges, reducing effects caused by changes in the angle of incidence or converging/diverging beams.
