In addition, we offer polarization rotators and depolarizers. As with all our products, we offer customization for our polarizers. Visit our product page for more detailed information for each polarizer. We look forward to your inquiry.

Home of high power optics and coatings

LASEROPTIK offers various types of polarizers, including thin-film (TFP) devices, cube polarizers (CP) and broadband polarizers (BBPOL). We can work in different wavelength ranges from the mid-IR (2.1 μm) to the UV (157 nm).

Precision Optics & Coatings for High Energy Laser Applications

Perkins Precision Developments (PPD) manufactures Brewster’s angle polarizers as well as 45 degree plate polarizers for high performance with easy alignment. Because we utilize Ion Beam Sputtering (IBS) coating technology, our dielectric thin film plate polarizers are environmentally stable, thus there is no spectral shift caused by either time, moisture or temperature. The predictability and repeatability of IBS thin film coatings allow us to guarantee high transmission at a specific angle of incidence, eliminating the need to angle tune the optical component in order to achieve optimal performance.

As with all of our custom laser optics and polarizers, PPD's IBS coated polarizing beam splitters exhibit low absorption, high extinction (T_p/T_s) and high damage thresholds, making them ideal for use with high energy Nd:YAG and fibers lasers as well as other high-power pulsed and CW laser systems throughout the visible and near-infrared.

Avantier produces high-quality dichroic polarizers with steep edges and flat reflection and transmission bands. Our polarizers provide almost complete transmission and reflection, resulting in high contrast images and good signal to noise ratios. They feature a UV grade fused silica, JGS1, or JGS2 substrate, and have a higher damage threshold than plastic polarizers. Our coatings meet MIL-STD-810F and MIL-C-484971 requirements, and we offer various options.

Edmund Optics offers a wide range of dichroic, crystalline, and wire grid polarizers which can also be used for polarization beam combining.

Your Custom Optics Expert

At Shanghai Optics we produce some of the highest quality dichroic polarizers. Our dichroic plate beamsplitters are manufactured with a special design and proprietary manufacturing approach, allowing us to attain steep edges and flat, high reflection and transmission bands.

The almost complete transmission and reflection provided by our dichroic polarizers means that very little stray light gets through the imaging system. This results in high contrast image and a very good signal to noise ratio, as compared to other polarizers.

Our dichroic polarizers feature a UV grade fused silica, JGS1, or JGS2 substrate, coated with a hard dielectric coating. These glass polarizers have a much higher damage threshold than their plastic counterparts, and are suitable for precision applications. Our coatings fully meet MIL-STD-810F and MIL-C-484971 requirements, and we have a variety of different options available.

Hangzhou Shalom EO offers a full portfolio of off-the-shelf and custom polarizers, comprising: Glan laser polarizers, Glan–Taylor polarizers, Glan–Thompson polarizers, Wollaston prisms, Rochon prisms, polarization plane rotators, and achromatic depolarizers.

Shalom EO utilizes various birefringent crystals including Calcite, Alpha-BBO, YVO₄, MgF₂, and quartz, with their transmission spectrum spanning from UV, VIS, to IR to fabricate our non-cubic polarizers. Anti-reflection coatings (single layer MgF₂ coating, broadband AR coating, and laser line wavelength V coating) and protective coatings are available both as standard and custom versions. Unique designs of the construction of the polarization optics are accessible, including air-gap, cement, black glass, and escape ports.

In addition, Shalom EO also supplies polarizing beamsplitter cubes (PBS cubes) with a maximum extinction ratio of T_p / T_s = 10000:1, high laser damage threshold, and minimized scattering loss.

A set of waveplates and retarders are available as well, such as super achromatic/achromatic waveplates, zero order waveplates, liquid crystal polymer waveplates.

Bringing quality into focus

At Knight Optical, we stock a vast range of polarisers suitable for a variety of applications, including linear and circular sheet polarisers, achromatic waveplates, zero and low order quartz retarders, and calomel infrared polarisers. We also offer custom polarisation optics including crystal polarisers, as well as Lyot depolarisers.

Your reliable partner for photonics innovations!

EKSMA Optics offers a complete range of polarization optics: thin-film polarizers, Brewster windows, cube polarizing beamsplitters, Glan laser polarizing prisms, Rochon and Wollaston prisms.

Your sidekick for laser optics development

OPTOMAN offers thin film polarizers, that are the optimal choice for polarizing high energy laser light. Thin film polarizers accomplish this task with a high efficiency level due to negligible absorption within the coating, transmittance (T_p) higher than 99%, and reflectance (R_s) as high as 99.99%.

OPTOMAN will provide an optimal solution in terms of extinction ratio (10'000:1 is possible), angle of incidence (various choices depending on application), and damage threshold (>49.4 J/cm² @ 1064 nm, 10 ns, 100 Hz can be achieved in some configurations). Broadband configurations for femtosecond applications are also feasible.

Standard in-stock IBS coated polarizers can be found in OPTOSHOP.

Lasers, Optics, Electronics. Made in Germany.

Most types for crystal polarizers like Glan–Taylor, Rochon, crystal wedge etc. covering the spectral range from 170 nm to 6 µm are available from stock. Thin-film polarizers used at Brewster or 45° angle of incidence feature high damage threshold and can be used for demanding applications. ALPHALAS also offers customer-specific polarizers.
