OPTOMAN’s Standard IBS-coated Non-Polarizing Beam Splitters engineered to split a laser beam into two virtually identical beams without disturbing the polarization ratio, making them a reliable choice for polarization sensitive laser applications. Optimized for operation at 1550 nm at a 45° angle of incidence, these beam splitters ensure exceptionally low losses and no polarization disturbance in Laser Communication systems.
Independently benchmarked in a gravitational-wave speed-meter context, this 5-layer beamsplitter shows a large acceptance angle, maintaining near-constant reflectivity and phase versus AOI, so polarization symmetry holds even with slight drifts in alignment.
