Once finalized, the resulting review and reply will be featured in an upcoming journal issue.

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.

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.

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.

The Army should be the air-ground littoral owner, and the battlespace should be qualified as an extension of the ground domain, providing necessary flexibility to the land component commander.

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.

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.

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.

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 2.5" form factor offers compatibility and ease of installation, while mSATA suits smaller devices with limited space. The M.2 form factor strikes a balance ...

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.

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.

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.

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.

The US Air Force should drive a reinvention of airpower concepts, including that of air superiority, as well as the close air mission, to fulfill its purpose and role as master of the air domain.

Onto this bare polarizer, additional treatments are applied such as an adhesive glue, hard coating, antiglare, anti-reflection and other surface treatments.

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.

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.

Affordable linear polarizing film is ideal for class demonstrations relating to polarized light experiments, rotator, light scattering, light reflection.

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.

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.

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 possibilities of small, uncrewed vehicles drive us toward a key question: How can airpower work together with our sister services to achieve victory together?

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.

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.

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.
