PBSH: Visible and Near-IR Broadband Polarizing Cube Polarizers
PBSH: Visible and Near-IR Broadband Polarizing Cube Polarizers
Broadband, high efficiency, high extinction ratio separation of s- and p-polarization for visible and near-IR. These broadband, high efficiency cube beamsplitters separate polarizations with an extinction ratio of > 500:1 for transmitted p-polarized light while reflecting > 99.5% of s-polarized light. They are available from stock for wavelength bands from 450 - 2000 nm for use at moderate power. Other wavelengths are and dimensions are available upon request.
