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
REO has the proven high volume capacity for manufacturing polarizing beamsplitter products using processes that are engineered and controlled to be high quality, high yield, and cost effective. Our established ISO 9001 certified quality system guarantees results that meet every specification, every time. |

| ur standard 50/50 beamsplitters use BK7 optical glass with dielectric coating on the hypotenuse surface. The outside surfaces have MgF2 with 60-40 scratch-dig. The surface flatness is 1 wave NR inch. Angle tolerance is ±5 arc minutes. |

PPC beamsplitter cubes are derived from a unique combination of IBS coatings, ultraprecise fabrication capabilities and our epoxy-free bonding technology--Chemically Activated Direct Bonding (CADB) which results in zero-bondline thicknesses. In addition to the standard sizes and wavelengths shown, we can produce high-energy cube beamsplitters from 1x1 mm2 in size, and in a wide variety of materials including fused silica, BK7, YAG and other optical glasses and industrial crystals.
Whether you need 10 or 10,000 pieces, our precision wafer-based processes result in high yields and competitive costs, especially at higher volumes. These high-precision assemblies have been widely used in telecommunications, semi-conductor and biomedical applications where transmission efficiency, extinction ratio and wavefront quality are all critical specifications.
Call us for more information on high-energy narrowband and broadband polarizing beamsplitter cubes for other wavelengths from 266nm to 2200nm, or to discuss your requirements for custom waveplates, polarizers and micro-optic assemblies. |

Thin Professional film Plate Polarizers and Dichroic Beamsplitters
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 professional 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.
Among the many diverse custom optical components that PPC offers are diode-pumped Nd:YAG resonator mirrors, 50/50 non-polarizing beamsplitters and thin-film plate polarizing beamsplitters. For all the optical components we provide, we use only ion-beam-sputtered (IBS) coatings. The IBS coating process is both accurate and repeatable, resulting in precision coatings that are easy to clean, chemically resistant and insensitive to moisture and other environmental factors. |

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 industrial crystal, dielectric beamsplitting, and dichroic.

A retarder, or retarder, is an optical device that resolves a light wave into two orthogonal linear polarization components and produces a phase shift between them. The resulting light wave generally is of a different polarization form. Ideally, retarders do not polarize, nor do they induce an intensity change in the light beam. They simply change its polarization form. Retarders are used in applications where control or analysis of polarization states is required.
Our retarder products include innovative polymer and liquid industrial crystal materials. Upon request, crystalline materials, such as quartz, magnesium fluoride, and sapphire, also are available.

PPC uses laser-grade industrial crystal quartz to produce multiple-order,
true zero-order and compound zero-order waveplates with retardations
of quarter-wave, half-wave or anything in-between.
Multiple-order retarders are ideal for narrow- or single-wavelength
applications at a specific operating temperature. For increased
bandwidth and thermal stability, zero-order waveplates
are recommended.
For compound zero-order waveplates and multi-element waveplate
assemblies, we use durable IBS coatings and our proprietary
epoxy-free bonding technology—Chemically Activated Direct
Bonding™ (CADB). This unique combination of processes results in
precise, high-energy components that exhibit environmental stability
and improved transmitted wavefront characteristics.
Waveplates are available as standalone
components, or as part of
a more complex optical assembly.
PPC manufactures custom
multi-element polarization assemblies
with and without
epoxy in sizes from 1 mm
to 1" for R&D, biomedical
and aerospace
applications. |
