Thin film laser optical polarizer
Precision Photonics
* Wide acceptance angle and no angle tuning required
* 45° design separates s and p by 90°; optional side 2 coating for R < 0.1%
* Extinction ratios greater than 1000:1 ; no AR coating necessary
* RoHs Compliant
These thin-film plate polarizers utilize our advanced ion-beam-sputtered (IBS) coating technology to achieve high-power performance and guaranteed transmission at a specific angle of incidence, with no angle tuning required. By combining durable dielectric coatings with fused silica substrates, we produce robust optical components that are stable, easy to align and exhibit high laser damage thresholds in both reflection and transmission.
High energy plate polarizers separate s and p polarizations with an extinction ratio (Tp/Ts) of greater than 750 to 1000:1 in the transmitted beam. Thus, they are ideal for intracavity or extracavity high-power applications where fluences are greater than 500 mJ/cm2 and calcite or cemented cube polarizers cannot be used. 45 degree and/or Brewster-angle plate polarizers are available for wavelengths from 355 nm to 3000 nm.
