Polarization Beam Splitter (PBS) Non-Epoxy Bonding

SKU: PBS

The Polarization Beam Splitter (PBS) is a cube-format optical component designed to separate an incoming light beam into two orthogonally polarized output beams. Unlike conventional PBS cubes that rely on epoxy or cement bonding, Agiltron PBS devices are fabricated using a proprietary direct optical surface bonding process that joins two precision-coated right-angle prisms without the use of organic adhesives. The elimination of epoxy and cement layers significantly improves long-term reliability, environmental stability, optical power handling, and resistance to thermal aging. Each PBS cube incorporates high-performance dielectric polarization coatings and precision-polished optical surfaces to achieve excellent transmission, reflection efficiency, extinction ratio, and wavefront quality. Agiltron PBS cubes are ideally suited for demanding applications in fiber-optic communications, coherent optical systems, laser instrumentation, sensing, aerospace, defense, and quantum photonics where high optical performance and long-term stability are critical.
