If you’ve ever wondered:
"Where to buy Polarizing Film at low price?" Then, you’re in the right site.
3Dlens Corporation supplies the highest quality linear polarizing film in a various sizes with superior extinction ratio and high transmittance of unpolarized light in the range of wavelength 400~700nm.
Our linear polarizer film sheet will not fade under normal exposure to the light. Under room temperature and humidity, the life will last for 10~20 years.
Basically the polarized 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 in additional protective film or with adhesive glue.
3Dlens have passed linear polarizing test for durability 60°C / 90%RH / 500Hours, so it is a good replacement for Polaroid and 3M HN32 & HN38.
High contrast linear polarizer 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.
We sell linear polarizer films to many countries as Australia, UK, France, Italy, Finland, Canada, India, Brazil, Deutsche, Singapore, America, and so on.
These linear polarising film sheets can be easily cut with scissors or a paper cutter.

The 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, LCD. In addition, cars, ships, aircraft, outdoor measurement equipment for the use of dye-based polarizing film such a durable polarizing film.
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.
The type of polarized light:
*Linearly polarized light - The polarized light whose direction of vibration does not change with time.
*Elliptical polarized light - the two orthogonal components of the direction of vibration of the electric field, the amplitude is not the same, the formation of elliptically polarized light.
*The circularly polarized light - the wave direction of the two orthogonal components of the vibration direction is not the same amplitude and amplitude, the formation of circularly polarized 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.

Your polarizing film has passed our R&D test... Sylvia (China)
I am really surprised how fine #P200A polarizer works with my mp3 player. Peter (Czech)
I purchased previously your linear polarizer. They work very well in a polarizing microscope. Andres (Spain)
Your polarizer film has excellent extinction and transmission properties and appears to be a cost effective solution for its size and price compared to Polaroid HN22 product. Neil (USA)
Transmission and efficiency are OK. They do the job very well. Bernard (Australia)
* Polarizing filter #P210 is performed in my application even better than 3M HN32 Polaroid film. Vlad (United States)
I want to do an inversion of the display monochrome LCD in the vehicle. What kind of film should I use to get a high quality inversion?
Answer: You need a linear polarizer film with/without adhesive to replace the old film.
Can you tell me that what difference between P620 and P620A polarizers?
Answer: The difference between P620 and P620A is that P620A has adhesive on one side, while P620 has NO adhesive on both sides.
