High Extinction Broadband Polarizing Cube Beamsplitter (BPB)
- Broadband visible use
- Low power applications
These polarizing cube beamsplitters provide a high degree of polarization over a broad visible spectral range. They are made by cementing the prisms together making them unsuitable for high power use. They use SF2 prisms and provide a high extinction ratio of at least 500:1.
