UPBS: UV Laser Line Polarizing Cube Polarizers
UPBS: UV Laser Line Polarizing Cube Polarizers
High efficiency, high extinction ratio separation of s- and p-polarization at UV laser wavelengths. These high efficiency cube beamsplitters achieve an extinction ratio of > 100:1 for transmitted p-polarized light while reflecting > 99% of s-polarized light at a single UV wavelength. They are available in standard wavelengths from 355 to 405 nm for use at power < 10 mJ/cm2. Other wavelengths are available upon request.
