Product Family Description

  • Multi-Layer Dielectric Coating
  • Several Beamsplitting Ratios Available
  • Multiple Sizes Available

Constructed by cementing two right angle prisms together, TECHSPEC® Standard Cube Beamsplitters offer a range of reflection/transmission ratios. An interference coating has been applied to the hypotenuse surface of one of the prisms to provide the designated reflection/transmission ratio. Absorption loss to the coating is minimal.

Note:  Output is partially polarized, making TECHSPEC Standard Cube Beamsplitters suitable for illumination and other applications where polarization is not a concern. If polarization sensitivity is critical to your application, we recommend using TECHSPEC® Polarizing Beamsplitters or TECHSPEC® Non-Polarizing Beamsplitters.
