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.

| NOTES! |
|
 |
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. |
|
Be sure to wear laser safety goggles when checking optical path and adjusting optical axis. |
