Polarizing Optics

Zero Phase Retarder – 0RSI/0RCU Series

Reflective Phase Retarders are used as beam bending mirrors external to the laser cavity to establish and maintain circular polarization. This requirement is particularly vital for laser material processing applications where cut or scribed edge quality, and weld  penetration, are critical to the consistency and precision of the final part. Zero degree phase retarders maintain control over the circularly polarized beam.

90° Phase Retarder – 90RSI/90RCU Series

90˚ phase retarders are used to convert linear polarization to circular polarization. Circular polarization means equal amount of s-pol and p-pol for any beam orientation. With 90˚ phase retarders used in cutting, material can be removed uniformly regardless of cutting directions.

ZnSe Thin Film Polarizer

Thin Film Polarizer (TFP) is used to split a laser beam into two parts with S and P Polarizations. Meanwhile, TFP can also be used to combine two beams with S and P polarizations. A TFP consists of a coated plate, which is oriented at Brewster’s angle with respect to the incoming beam. The thin film coating is able to enhance the reflectivity of the s-polarized component of the beam, and maintain high transmission of the p-polarized component.
