If you have ever wondered: "Where to buy a Polarizer Film at low price?" Then, you are in the right site.
3Dlens Corporation's online shop supplies the highest quality pre-cut linear polarizing film in a various sizes near the A4 ~ A1 with superior extinction ratio and high transmittance of unpolarized light in the range of wavelength 400~700nm.
Our linear polarizer film material will not fade under normal exposure to the light. Under room temperature and humidity, the life will last for 10~20 years.
Basically the linear polarizer film structure is by 3 layers material; polarizing membrane PVA (Polyvinyl alcohol) and support layers TAC (Tri-acetate cellulose) on its both sides.
It is the most commonly used for additional protective film or release film with self-adhesive backing.
3Dlens have passed a linear polarizing test for durability 60°C / 90%RH / 500 Hours, so it is a good replacement for Polaroid and 3M HN32 & HN38.
High contrast linear polarizer film sheet is perfect for a wide range of imaging applications and all kinds of experimentation.
Affordable linear polarizing film is ideal for class demonstrations relating to polarized light experiments, rotator, light scattering, light reflection.
The applications of polarized film are 3D glasses for movie, polarized sunglasses, polarized fishing glasses, polarizing microscope, camera filter, photography studio light, polariscope, rotating filter by using two polarizers, photoelastic stress analysis, glare reduction, speedometer instrument cluster, window light control, Nintendo Gameboy, monochrome LCD, STN black & white monitor, 3d printer, calculator, dental photography and DIY experiment.
We sell 0 degree & 90 degree linear polarizer to American, India, Pakistan, Malaysia, Singapore, Australia, Canada, UK, Philippines, NZ, France, Italy, Finland, Brazil, Germany and so on.
These linear polarizing film sheets can be easily cut with scissors, knife or a paper cutter.RoHS compliant.

It is a filter sheet which allows a specific polarization of light waves to pass through and block other light called a polarizer sheet (polarizing film) or Polaroid filter.
The earliest artificial polarizer was invented by Polaroid company Edwin H. Land in 1928. Although it has 94 years of history, but the process principle and material are still roughly the same.
Polarized films are widely used in research labs, the optical industry and equipment. Commercially available polarizers are made from different materials such as glass, crystal or plastic.
Plastic polarizer films are the least expensive and commonly used in liquid crystal display such as screens of calculators or computer monitors, polarized sunglasses, and 3D movie glasses.
Protective film used to protect the polarizing plate surface, consumers need to tear the film when use a polarizer.
Onto this bare polarizer, additional treatments are applied such as an adhesive glue, hard coating, antiglare, anti-reflection and other surface treatments.
At present there are two types of polarizers in the market: iodine polarizing film and dye type polarizing filmThe general process, the first is to produce a polarized film, hydrophilic PVA. After the film is swollen, it is immersed in a dichroic dye solution and stained.
The dichroic dye is usually a solution of iodine and potassium iodide. And then extend the dyeing film, extending to give the Dichroic dye arrangement, the higher the order, the prepared polarizing film optical properties are better.
After the extension of the film after drying, easy to stretch the direction of brittle fracture.
The iodine polarizing film has a high permeability, high contrast and a wide range of wavelength bias characteristics, the price is relatively cheap, so for a wide range of applications.
The polarizing property of the dye-based polarizing film is inferior to that of the iodine system, but the wet heat resistance characteristic is good and belongs to the durability polarized film.
Iodine standard linear polarizing film applications is in a wide range, such as watches, calculator computers, PC, OA machines. In addition, cars, ships, aircraft, outdoor measurement equipment for the use of dye-based polarizing film such a durable polarizing film.Polarized light:
Light is an electromagnetic wave, the general light in the forward, the electromagnetic vibration direction in all directions. If the electromagnetic vibration occurs only in a plane, that is, the direction of the electric field vibration and magnetic field direction fixed light is called polarized light. The direction of its electric field is called the polarization direction of light.
It is through the electromagnetic or mechanical action to have dichroic acid quinine sulfuric acid small crystals neatly arranged in a transparent plastic film made of.Artificial polarizer as a result of a simple manufacturing process, cheap, and can be made into a larger area, which has been widely used.
At present in the general polarization instrument and many of the partial and the partial detection device using artificial polarizer.
For example, when watching a three-dimensional movie, the audience needs to wear a pair of glasses, which is a pair of vibration perpendicular to each other polarized film.
The principle is that we usually only use two glasses to see the object to produce three-dimensional sense, if the use of two shots, such as the human eye, from two different directions at the same time takes the film scene image, made positive film.
In the projection through the two projectors with the vibration direction perpendicular to each other, two linearly polarized light superimposed on the screen, the human eye through the above polarized glasses to watch, each eye can only see a corresponding independent image, Like a direct view to produce a three-dimensional feeling.Manufacturing of plastic polarizers:
Polarized film is created from rolls of polyvinyl acetate (PVA). The process begins by heating and stretching PVA to a much longer and thinner sheet.
This lengthens PVA's long chain molecules, causing them to align. The stretched PVA is then dipped in iodine solution.
The iodine is absorbed into the molecular chains forming long grids of parallel and darkened lines. The film is then dyed to the color of the desired finished film.
The darker the film, the more polarization it provides. Once the PVA is dyed and dried, it is delicate and hard to handle. To stabilize it, the film is mounted on a sheet of cellulose acetate butyrate (CAB).
Here are some reviews from our customers:These polarizer sheets arrived packed very securely so they could not get warped in the post. The company processed my order very quickly and provided good tracking information. The polarizer sheets work very well and I'm hoping that I can use them to repair an old graphics LCD module if I can get the residue of the old polarizers off it. Bob (Australia)
