Polarizers allow the transmission of only one polarization state. A linear (or plane) polarizer transmits light polarized in a single plane.
Meadowlark Optics now offers four types of linear polarizer: wire grid, calcite crystal, dielectric beamsplitting, and dichroic.
Our Polarizer Selection Chart provides an at-a-glance review of standard polarizers available from Meadowlark Optics. |

The Radial Polarization converter is a worldwide unique device that converts a conventional linearly polarized beam into a beam that has a continuous radial or azimuthal polarization distribution.
This Radial polarization converter is based on a special liquid crystal cell with variable molecular twist.The device generates a homogenous intensity at the output and induce only minimal convertion losses of about 10-30%.
Also the Polarization converter works fine for monochromatic as well as polychromatic light ranging from 400nm to 1700nm. |

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 |
