Sebopeho sa polarizer .
Polarizer ke mofuta wa filimi optical bopilwe ka multi-lera polymer thepa, e leng na le mosebetsi oa ho hlahisa polarized leseli. ho ea ka tshebediso ya lona boemo ba seela kristale skrine, e ka ka kakaretso arotsoe ka mefuta e 'meli: patch (e tsejoang hape e le phetiso filimi) le negative (e tsejoang e le reflection filimi).

According to the drawing technology, it can be divided into two series: dry drawing and wet drawing. Changing its material and processing technology can realize the adjustment of the polarizing degree, transmittance, tone and optical durability TAC layer: the polarizing layer made of PVA film is easy to absorb water, fade and lose polarizing performance. Therefore, a layer of TAC (cellulose triacetate) Filimi yeo e nago le go swana mo go botse ga optical le go ba pepeneneng e a nyakega ka mahlakoreng ka bobedi go arola meetse le moya le go šireletša lera la polarizing. la TAC ka mešomo ya UV yeo e segwago le go lwantšha go phadima e ka šomišwa go dira UV le di-polarizers tša go lwantšha glare.
