PBS: Visible and Near-IR Laser line Polarizing Cube Polarizers
PBS: Visible and Near-IR Laser line Polarizing Cube Polarizers
High efficiency, high extinction ratio separation of s- and p-polarization at visible and near-IR laser wavelengths. These high efficiency cube beamsplitters achieve an extinction ratio of > 1000:1 for transmitted p-polarized light while reflecting > 99.9% of s-polarized light at a single visible or near-IR wavelength. They are available in standard wavelengths from 532 to 1550 nm for use at power < 10 mJ/cm2. Other wavelengths are available upon request.
