Thorlabs' film polarizers are designed to linearly polarize large, low-power beams of light. Each film polarizer is a square that can be cut to custom sizes or left whole to polarize large beams. There is a protective film on both sides of each polarizer that must be removed prior to use. 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 applied to the protective film. 

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.

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.

It's simply too small for me.

Hello, larger sizes of up to 24" x 39" are available. We will contact you directly to find out more about your application and see what size and quantity you are interested in.

Hi Sirs, I need 4x4" of this polarizer. Is it possible to order this size?
nbayconich  (posted 2017-07-27 03:25:51.0)
Thank you for contacting Thorlabs. We can provide these as custom items. A techsupport representative will contact you directly.

Hi, I'm looking for Linear Polarizer sheet(4"x4") with high transmission (>80%) at 405nm wavelength. Is it available here? Please email me.
jbell  (posted 2015-09-03 17:38:47.157)
The transmission is shown as 80% over most of the spectrum. I am measuring more like 40%. Are you certain this is the correct transmission chart? Thanks, John.
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 the damage threshold? Thanks!
besembeson  (posted 2015-02-26 04:17:55.0)
Response from Bweh at Thorlabs: We have not tested these specifically. But we have tested the economy laminated film polarizers whose values you can use as a guide: http://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=4984&pn=LPVISE050-A#7210

Is there a temperature SPEC available for this product??
jlow  (posted 2014-09-25 09:36:46.0)
Response from Jeremy at Thorlabs: The polarizing film is rated for -50°C to 70°C.
vkorman  (posted 2014-03-10 14:05:19.773)
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°.
debordet  (posted 2013-10-22 19:20:26.817)
Is it possible to get this material in a 4x4" size?
jlow  (posted 2013-10-23 10:53:00.0)
Response from Jeremy at Thorlabs: We can provide this in 4"x4" size. I will contact you directly for a quote.

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.

To explore the available types, wavelength ranges, extinction ratios, transmission, and available sizes for each polarizer category, click More [+] in the appropriate row below.

  • Mounted in a protective box, unthreaded ring, or cylinder.
  • Available unmounted or in an SM05-threaded (0.535"-40) mount that indicates the polarization axis.
  • Available unmounted or in an SM1-threaded (1.035"-40) mount that indicates the polarization axis.
  • Available unmounted or mounted in cubes for cage system compatibility.
  • Calcite's transmittance of light near 350 nm is typically around 75% (see Transmission column).
  • Available unmounted or in an unthreaded Ø1/2" housing.
  • The transmission curves for calcite are valid for linearly polarized light with a polarization axis aligned with the mark on the polarizer's housing.
  • The 1064 nm V coating corresponds to a -C26 suffix in the item number.
  • Available unmounted or mounted in a protective box or unthreaded cylinder that indicates the polarization axis.
