Buying Thin-film Polarizers

thin-film polarizers

Top-level product category: icon optical components and devices

More general product categories: polarizers

Thin-film polarizers are designed for various operation wavelengths and can handle very high optical powers. These structures are used in plate polarizers and polarizing cubes, essential for controlling polarization in high-power optical systems.

Making Good Purchase Decisions

As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.

NEW: Structured Decision Process

Purchasing involves a lot of responsibility. We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.

Our article on best practices for purchasing and another one explaining this tool give you valuable insights.

1. Understand the technical background

It is important to sufficiently understand the technology before buying.

Use the comprehensive learning resources of RP Photonics:

If you need personal help, contact RP Photonics to get technical consultancy.

2. Define your requirements

It is essential to fully understand and clearly define your requirements before you buy.

We recommend that you develop a list of clear specifications according to your specific needs, against which you can later check the suitability of found product offers:

To help you, we have already listed some aspects we recommend you consider when buying thin-film polarizers. Of course, there may be other aspects that are relevant to your specific case.

This list is for your own preparation, and can later (possibly in modified form) be used for quotation requests to suppliers.

Otherwise, you will need to talk to your technical colleagues.

If you cannot sufficiently clarify your requirements, you may want to get technical consultancy from RP Photonics.

You find these buttons in the supplier list below or under "3. Find suitable suppliers".

3. Find suitable suppliers

We suggest three steps:

  • Below, you can find our list of suppliers for thin-film polarizers. Use the checkboxes to mark possibly suitable suppliers.
  • The selected suppliers will appear below this list, along with your list of specifications. You can then indicate which specifications they meet according to your research. (You should finalize your specifications before doing this.)
  • Based on the results, you can finally choose a supplier that is hopefully a good enough fit.

thin-film polarizers

Perkins Precision Developments (PPD) offers high-performance Brewster’s angle polarizers and 45-degree plate polarizers featuring easy alignment. Utilizing advanced Ion Beam Sputtering (IBS) coating technology, our dielectric thin film plate polarizers are environmentally stable, ensuring no spectral shift due to time, moisture, or temperature. The precision of IBS coatings guarantees high transmission at specific angles of incidence without the need for angle tuning.

PPD's IBS coated polarizing beam splitters are designed for low absorption and high extinction (Tp/Ts), with high damage thresholds suitable for high energy Nd:YAG and fiber lasers, as well as other high-power pulsed and CW laser systems in the visible and near-infrared spectrum.

thin-film polarizers

Optogama’s high-contrast thin-film polarizers are engineered for performance in demanding laser environments.

Leveraging ion beam sputtered (IBS) coating technology, these polarizers deliver an exceptional extinction ratio (Tp:Ts > 1000:1), ensuring clean polarization separation even at high power densities. With outstanding surface quality and LIDT, they are built to thrive in both scientific-grade systems and industrial-class lasers.

Key advantages:

  • Wavelength range: from deep UV at 230 nm to the near-IR at 2000 nm—these optics support a wide range of laser platforms.
  • High-Power Ready: Optimized for high LIDT, they excel in environments with intense beam exposure.
  • Scalable Design: Aperture sizes up to 160 mm accommodate large beam diameters without compromising uniformity.
  • Custom Solutions: Tailored coatings, sizes, and mounts—engineered for integration into your unique optical path.

thin-film 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 (Tp) higher than 99%, and reflectance (Rs) 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.
