Thorlabs' film polarizers are designed to linearly polarize low-power beams of light. Each film polarizer is a square that can be left whole or cut to custom sizes. The polarization axis is marked with an arrow and is aligned to the flat edge of the LPVISE2X2, while the polarization axis of the LPNIRE2X2 and LPNIRE11S is noted by a sticker. There is a protective film on both sides of each polarizer that must be removed prior to use.

The polarizing materials are designed and optimized for use within their operating range, denoted in the graphs below by the blue highlighted regions. Outside of this range, the performance of these polarizers' is not guaranteed. Care should be taken when cleaning and mounting these polarizers, as significant stress may cause performance variation. We recommend using compressed air to remove dust and debris.

These polarizers may slightly diffuse the transmitted beam and are not recommended for imaging applications or applications that require the input divergence to be preserved. Similarly, they may not maintain the collimation of large input beams. The beam will walk as the polarizer rotates, so it is recommended to use these polarizers only when a single fixed polarization direction is needed. Rotation assemblies, like the one shown to the right, should be used only to set a fixed output angle.

Larger sizes of up to 24" x 39" are also available. To order a custom-sized film polarizer, please contact Tech Support. We also offer film polarizers with AR-coated windows epoxied on each side in Ø1/2", Ø1", and Ø2" sizes.

Hello, we are planning to use the economic film polarizer, LPVISE2X2 for an upcoming project. We are just wondering if they are available for sterilization. If it is, what kind of sterilization process is appropriate? Thank you. Best regards,

Thank you for reaching out to Thorlabs. You can request additional data and information by reaching out to techsupport@thorlabs.com. I have contacted you directly to discuss different possibilities for this.

Hi We are interested in looking at possibly buying LPNIRE2x2 for an upcoming project. However, we would want to know the transmission spectrum of the polarizer at sub-500 nm wavelengths as well. This is currently unavailable on the website. Could you please send us the raw transmittance data corresponding to the wavelength range 300-900 nm?
cdolbashian  (posted 2022-08-15 04:47:39.0)
Thank you for contacting Thorlabs. LPNIRE2X2 is designed for 600-1100nm, the performance beyond the optimized band cannot be guaranteed. That being said, we do have 400-1200nm test data to share. We will reach out to you directly via email.

Dear Thor Labs team, we are currently looking for new, cost-efficient polarizer films for our products. Therefore, we noticed your UV-vis polarizer film (LPVISE2X2). How high would be the price per m² of this polarizer film? May you please send me the data sheet for this product? And may we ask you for a sample? Sincerely, M.Sc. Jakob Zubek insensiv GmbH
cdolbashian  (posted 2022-07-26 04:22:00.0)
Thank you for reaching out to us with this inquiry! For your first and third questions, I have put you in contact with your local tech support office. As for the data sheet of this product. All of our data sheets can be found by clicking the red "docs" icon adjacent to the desired product name. You will find the spec sheet there.

Hello, I need a film polarizer for 800 nm to have a linear polarization after transmitting through the film. LPNIRE2X2 looks fine but I'am a little bit confused by the title: "Diffuse Reflective Film Polarizer" hope it doesn't diffuse transmitted light, right?
cdolbashian  (posted 2022-06-20 09:32:36.0)
Thank you for contacting Thorlabs. These polarizers may slightly diffuse the transmitted beam and are not recommended for imaging applications or applications that require the input divergence to be preserved. For polarizers with minimal scatter, please see our Nanoparticle Linear Film Polarizers (https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=752). Custom/Larger sizes are also available for some Nanoparticle Linear Film Polarizers, please feel free to contact local Tech Support team (in your case, Europe@thorlabs.com) if needed.

Is it possible for the customer to cut the film to a specific shape, with a cutter, a pair of scissors, or at least with a specific laser source? I want to reproduce the cross polarisation present in microscopes, where the objective has one fixed linear polarizer and illumination has one rotating analyzer. Thanks
YLohia  (posted 2021-04-22 10:23:23.0)
Hello, yes, these polarizers can easily be cut by the end-user into various sizes to fit the needs of their experiment.
Richard Schuster  (posted 2020-08-18 03:48:02.663)
Hello, Could you please add to the product overview an information about a phase retardance of the substrate? E.g. while crossing two LPVISE2X2 polarizers, no light comes through, however when inserting the third one between them, light transmits through the three. It would be nice have the effect quantified (or at least be informed) before byuing the polarizer.. Thank you! Kind regards, Richard
nbayconich  (posted 2020-08-18 01:59:12.0)
Thank you for your feedback and suggestion, we could potentially add this to our product description. Please note that this phenomenon is a well known quantum mechanical effect seen with any type of polarizing material, regardless of the construction of the polarizer. This effect is known as Bell’s Theorem.
Rao Yelamarty  (posted 2020-02-20 12:46:25.273)
Hello, For an unpolarized white light source, what kind of transmission should I expect from these polarizers - 40% or 80%? Please advise. Thank you. Best Regards, Rao
llamb  (posted 2020-02-21 12:44:03.0)
Hello Rao, thank you for contacting Thorlabs. You should expect an average of ~38% transmission for an unpolarized white light source on our visible economy polarizers. The ~80% transmission is only if your input is a linearly polarized beam aligned with the polarization axis of the polarizer.

besembeson  (posted 2015-09-14 10:59:08.0)
Response from Bweh at Thorlabs USA: The transmission curve is correct and it is for a linearly polarized source. I will followup with you via email regarding your observations.

What is polarization axis (is it aligned with one of the flat edges, etc, or is it arbitrary)? If it is fixed to an edge, what is the tolerance on that spec (+/- angle)?
jlow  (posted 2014-03-11 08:36:39.0)
Response from Jeremy at Thorlabs: The polarization axis is aligned to one of the flat edges and will be marked with an arrow. The tolerance is ±2°.

Polarizer Selection Guide

Thorlabs offers a diverse range of polarizers, including wire grid, film, calcite, alpha-BBO, rutile, and beamsplitting polarizers. Collectively, our line of wire grid polarizers offers coverage from the visible range to the beginning of the Far-IR range. Our nanoparticle linear film polarizers provide extinction ratios as high as 100 000:1. Alternatively, our other film polarizers offer an affordable solution for polarizing light from the visible to the Near-IR. Next, our beamsplitting polarizers allow for use of the reflected beam, as well as the more completely polarized transmitted beam. Finally, our alpha-BBO (UV), calcite (visible to Near-IR), rutile (Near-IR to Mid-IR), and yttrium orthovanadate (YVO4) (Near-IR to Mid-IR) polarizers each offer an exceptional extinction ratio of 100 000:1 within their respective wavelength ranges.
