Linear polarizing film
Linear polarizing film is a specialized film that only transmits light waves aligned with its polarization plane (see also: polarization). Light passing through the film becomes linearly polarized.
If we compare the polarizing film’s grid filter to the “teeth of a comb,” only waves vibrating along the “teeth” will pass through, while those vibrating perpendicular will be blocked. Of course, like all phenomena occurring at the microscopic level, for such a filter to work, the actual spacing between the “teeth” must be extremely small. This requirement makes manufacturing an effective polarizing film a highly complex technological process.
The film converts unpolarized light into a linearly polarized wave.
Linear polarizing film has a structure resembling micro-louvers. The width of the gaps in this structure must be precisely adjusted to the wavelength of the light wave, requiring a highly complex manufacturing process.
It works on the principle of selective transmission – the film only passes light waves aligned with its polarization direction, while other components of the electromagnetic wave are blocked.
The film is easy to process; it can be cut using a special knife or ordinary scissors.
The film has a special water-activated adhesive applied on the inner side, so no additional components are needed to apply it. The film can be mounted on glass and other similar flat materials (organic glass, acrylic, plexiglass).
Installation is fully reversible; the film can be removed without damaging the surface it was applied to.
