Thin Film Polarizers (TFPs) can split a laser beam into two parts with orthogonal polarizations. Conversely, TFPs can be used to combine two beams with orthogonal polarizations. TFPs consist of a coated plate, which is oriented at Brewster’s angle with respect to the incoming beam. The thin-film coating serves to enhance the beam’s s-polarized reflectivity, while maintaining the p-polarized component’s high transmission.

The 50% / 50% visible Cube Beamsplitter consists of two cemented right angle prisms. One prism is coated on the hypotenuse to provide a coating that will reflect and transmit the incident light. The coating shows minimum sensitivity to variations in angles of incident and polarizations as compared to plate beamsplitters. The cube beamsplitter generally enables the optical system to have greater resolution than is possible with a plate type beamsplitter since asymmetrical optical aberrations are eliminated. The Cube Beamsplitter is also available in any split between reflection and transmission on special order.

Thin Film Plate Polarizers
Wide acceptance angle and no angle tuning required
45° design separates transmitted and reflected beams by 90°
Brewster-angle design separates polarizations with < 1000:1 extinction ratio
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.
For other wavelengths throughout the visible and near-IR (including Nd:YAG and fiber-laser wavelengths), substrate sizes or angles of incidence, please contact us.

REO's thin film polarizing beamsplitters offer industry leading performance created to the highest standards of quality and verified by state of the art functional metrology. Our high energy Ion Beam Sputtering coating process along with our proprietary adhesive-free bonding process insure that our beamsplitters will exceed all Telcordia requirements for durability and reliability.With the best extinction and bandwidth specifications in the industry, REO's polarizing beamsplitters are ideal for demanding polarization diversity applications such as interleavers, switches, circulators, and isolators. REO offers these polarizers in single hypotenuse versions, with right angle deviation between s and p output beams, or double hypotenuse versions, with parallel output beams. They feature the high power handling capability necessary for pump combination applications, and can be customized to match the most demanding requirements for size and cost. REO's beamsplitters can be integrated with our etalons or prisms using our adhesive-free bonding process to make assemblies that provide a precision drop-in optical solution that reduces costly assembly and alignment time
