Sheet polarisers

What are you looking for in Stock?

Knight Optical stock a range of UV/IR and Visible type sheet polarisers. These sheet polarizers are stocked as CAB laminated sheets for convenient cutting.

UV and IR sheet polarisers: Both HR polarisers and HNP’B polarisers are from the former Polaroid/ 3M range. Original HNP’B polariser is now obsolete however we supply a similar replacement that works extremely efficiently into the UV wavelength at 290nm. Our UV and IR sheet polarisers extend the spectral range down to 290m for the HNP’B replacement material and HR is used between 800nm to 2000nm. We have extensive stock of HR material in 76.2mm square sheets. The range from 800-860 the HN7 type offers superior performance at a reduced price. Working below 800nm HN22 is an ideal choice. 

Visible sheet polarisers: These sheet polarisers were previously made by Polaroid/3M and marketed under the brand name ‘Vikuti’ are now obsolete, however Knight Optical still hold substantial stocks. Some of the material grades are also being replaced by alternatives. Original Polaroid/3M ‘Vikuti’ sheet polarisers are offered in a wide range of types HN32, HN38 and HN42, and special high performance types HN22, HN38S and HN42HE.

As we hold large stocks of the 3M original polarisers in full sheets we can offer custom sizes at short notice. Some of the polarisers that are gradually being replaced with a equivalent polariser material are also available in large sheets.  See our stock list of stock sheet polarisers.

Alternative acrylic laminated and AR coated glass laminated polarisers can be offered at short notice, please enquire.
