Where to Buy Thin-film Polarizers

Optogama standard high contrast Brewster-type and 45° thin-film polarizers provide high extinction ratio T_p:T_s > 1000:1 thanks to the ion beam sputtered (IBS) thin-film coatings. Moreover, these polarizers are ideal for high-power levels and in the UV.

Optogama designs and manufactures standard and custom Brewster-type high contrast polarizers for the wavelength range between 230 nm and 2000 nm with face dimensions up to 160 mm.

Shanghai Optics can provide all types of anti-reflective, high reflective, and partial reflective coatings. We produce a wide variety of coatings from a single layer of anti-reflective coating to complex multilayer dielectric stacks. Types of dielectric coatings are BBAR, V-coatings, dual wavelength coatings, and sharp cut-on and cut-off filters.

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.

Avantier is capable of delivering a broad range of coatings, including anti-reflective, high reflective, and partial reflective coatings. Our coating offerings vary from simple anti-reflective coatings to intricate multilayer dielectric stacks. Examples of dielectric coatings include BBAR, V-coatings, dual wavelength coatings, and filters with sharp cut-on and cut-off wavelengths.

Artifex Engineering offers custom dielectric thin-film polarizers with a high damage threshold. Our thin film polarizers are commonly used for Q-Switching and other high power applications. These components are dielectric coated glass substrates designed for use at the Brewster angle. Visit our product page for more information. We look forward to your inquiry.

EKSMA Optics has a wide range of BK7 and UV fused silica thin film laser polarizers for quick delivery. Thin film polarizers feature high laser damage thresholds and are designed for the most demanding applications with Nd host lasers operating in the 1040–1070 nm range and with femtosecond Ti:sapphire or Yb:KGW/KYW lasers.

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).

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.
