Polarizing Beamsplitters

Excelitas provides two high-performance polarization cube technologies for a wide range of applications. Our Thin Film Polarizer Cubes use advanced dielectric coatings to achieve broad spectral bandwidth, high transmittance, and extinction ratios greater than 10,000:1. These qualities make them well-suited for demanding laser, imaging, and analytical systems.

For applications that require precise separation of transmitted and reflected polarization states within defined wavelength bands, our Polarizing Beamsplitter (PBS) Cubes with optimized TSWP coatings deliver exceptional performance, achieving transmission extinction ratios exceeding 1,000:1 for specific single wavelengths.
