Meadowlark Optics’ Beam Separators are designed for laser line applications and consist of a true zero-order quarter-wave retarder aligned with its fast axis at 45° to the transmission axis of a Laser Line Beamsplitting Polarizer. The transmitted beam is circularly polarized, regardless of the input beam polarization state. Our true zero-order Precision Retarders are quarter-wave within ± λ/350 and aligning the fast axis to within 1° ensures greater than 99.8% source isolation from specular back reflections.
