Polarizing cube beamsplitters separate the s- and p-polarized components of an incident beam into two highly polarized output beams separated by a 90-degree angle. A 50/50 split in laser energy is achieved for unpolarized incident light.
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 prisms.

Notes |
| |
»| Custom size is available upon requested and please contact us for OEM pricing. |
| |
»| The hybrid coating is a composite coating consisting of a dielectric multilayer film and a metallic film, which results in less light absorption than chrome and less dependency on light polarization than dielectric multilayer films. |
| |
»| The transmittance curve is a graph based on actual measurements and may vary from production lot to production lot. |
| |
»| The surface flatness is the reflected wavefront distortion of the surface before coating. |
| |
»| Plate-type nonpolarizing beam splitters are also provided upon request. |
