Where to Buy Polarizers

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, angle of incidence, and damage threshold. Ion-Beam Sputtering (IBS) technology enables us to manufacture polarizers with an extinction ratio higher than 10000:1 at a 45° angle of incidence while maintaining a >18.7 J/cm² damage threshold (1064 nm, 10 ns, 100 Hz).

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

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.

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.

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).

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.

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.

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.

Artifex Engineering offers a wide range of polarizers including crystal polarizers (Glan-Taylor, Glan-Thompson, …), dielectric polarizers, dichroic polymer polarizer sheets and wire grid polarizers. 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.

Shalom EO offers a full portfolio of polarizers and waveplates: Glan Laser polarizers or prisms, Glan Taylor polarizers or prisms, Glan Thompson polarizers or prisms, Wollaston polarizers, Rochon polarizers, high power laser line PBS, polarizing cube beamsplitters, non-polarizing beamsplitter cubes, polarizing plane rotators and achromatic depolarizers are also provided.

For non-cubic polarizers, used birefringent crystal materials include alpha-BBO, YVO₄, quartz and MgF₂. Modules including custom shapes and rectangular or round mount options are available. Please visit our website for more information.

Shalom EO offers optical prisms of multiple types which are ideal for applications of ray deviation and adjusting orientation of an image, including: right angle prisms, corner cube retroreflectors, wedge prisms, Brewster angle prisms and equilateral prisms, in addition to penta prisms, Dove prisms and roof prisms and Porro prisms. A large list of materials can be used: BK7, N-BK7, UV-grade fused silica, N-SF11, CaF₂, Ge, ZnSe.

Anti-reflection(AR) coating options are single layer MgF₂ coating, broadband AR coating and laser line wavelength V-type coating. Reflective aluminium coating is also provided.

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.
