Sheet linear type polarizer’s are optical filters used for absorbing light oscillations in a certain plane. When light is un-polarized light is oscillated in many directions, but if light passes through a sheet polarizer the oscillations become confined to a single linear plane. The “linear” polarized light can then be used to eradicate glare for use in various applications such as LCD monitors and photography. Our sheet polarizer’s are available as UV grade, Visible Grade and Infrared grade.
Former 'Polaroid' materials were made by 3M under the name 'Vikuiti' but is no longer produced.
When available on surplus stock we offer original 3M sheet polarizer’s (HN22, HN32, HN38, HN38S, HN42, HN42HE, HR, HNPB and HN7 types) but also equivalent replacement sheet polarizer material.
Visible grade sheet polarizer’s are available in sheets up to 39”x24” and 0.28mm and 0.7mm thk with CAB/ CAT/ Acrylic and glass laminations.
We still hold large stocks of HN38S sheets of 0.75mmth/ IR type HR polarizer as 3”x3” squares for use between 800nm to 2000nm/ replacement UV polarizer HNP’B that works in UV wavelength at 290nm.
