Purchasing advisor for polarizers with supplier directory and AI-based advice; wire grid, absorptive, polarizing cubes, thin-film polarizers, dichroic polarizers (original) (raw)

Find all you need for professional sourcing of polarizers: a comprehensive expert-curated directory of suppliers, scientific and technical background information, and an interactive AI-based tool with guidance for a structured decision process.

NEW: Not only hardware can be listed here, but also consulting, software, training on polarizers, etc. – see the "offer types" below.

🌐 You appear to be visiting from North America. Many listed suppliers are based in this region, making the RP Photonics Buyer's Guide highly relevant for your needs.

Purchasing high-value photonics products is a substantial responsibility. Using a structured decision-making process and high quality supplier data helps a lot:

• Find all relevant suppliers (not limited to advertisers).
• Our interactive tool conveniently assists you in defining and applying your application-specific requirements.

Note that purchasing decisions based on just a few randomly picked suppliers and without carefully defined specifications are risky; therefore, we strongly recommend using our data and tool. See also:

• How Responsible Purchase Decisions for Expensive Goods Like Lasers Are Done
• Explanations on this purchasing tool

Go through the process:

1. Understand the technical background

2. Define your requirements

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

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 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.

I think that I am sufficiently informed about our requirements.

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

I consider the above list of specifications to be sufficiently complete, clear and accurate.

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

Insert these criteria when creating inquiry mails to suppliers with the buttons "Get quotation".

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 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.

Selected suppliers:

Decision

The most suitable supplier you found:

Comments, e.g. reasons for your choice, or things which still need to be checked:

4. Document the decision process

It is essential to document your purchasing process, not only its result (chosen supplier):

• You will find it easier next time.
• If something goes wrong, you can defend your decision by showing that you properly considered all important aspects. Or you see what needs to be done better next time.

Our interactive tool makes it easy: Fill out the form, and in the end print it to a PDF. Note that the document will show all sections (including those not currently shown on the screen), while omitting some irrelevant details such as the page navigation.

Your Custom Optics Expert Shanghai Optics Inc.425 Main St Suite 2EMetuchen, NJ 08840United States

⚙ hardware 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. Product-specific web page

Precision Optics & Coatings for High Energy Laser Applications Perkins Precision Developments4110 North Valley DriveLongmont, CO 80504United StatesSee us at Photonics West 2026 in San Francisco, Jan. 20–22 (booth 2048)!

⚙ hardware 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 (Tp/Ts) and high damage thresholds, making them ideal for use with high energy Nd:YAG and fiber lasers as well as other high-power pulsed and CW laser systems throughout the visible and near-infrared. Key features of PPD's Polarizer Cubes and Plate Polarizers include: Low absorption and high damage thresholds (>20 J/cm2) Ideal for high energy Nd:YAG and fiber lasers, as well as other high-power pulsed and CW laser systems Space-flight qualified Durable, stable and epoxy-free Product-specific web page
