Polarizer ama sidoo kale loo yaqaan saxanka hirarka ama dib-u-dejinta waa aalad indho-indhayn ah oo beddeleysa xaaladda mawjadaha iftiinka ee dhex mara.
Laba mawjadood oo caadi ah waa mawjadaha kala badh, kuwaas oo beddela jihada polarization ee iftiinka toosan, iyo rubuc-waveplates, kuwaas oo u beddela iftiinka toosan ee iftiinka wareega iyo beddelka.Taarikada mawjadaha rubuc sidoo kale waxaa loo isticmaali karaa in lagu dhaliyo polarization elliptical.
Polarizers, ama mowjadaha mawjadaha sida loogu yeero, waxay ka samaysan yihiin walxo birefringent ah (sida quartz) kuwaas oo leh calaamado kala duwan oo dib u soo celinta iftiinka tooska ah ee mid ama mid kale oo ka mid ah laba faashad crystallographic gaar ah.
Cutubyo kala duwan ayaa loo adeegsadaa codsiyada sawir-qaadista si loo dhimo dhaldhalaalka ama meelaha kulul, kor loogu qaado isbarbardhigga, ama loo sameeyo qiimaynta walaaca.Polarization waxa kale oo loo istcimaali karaa in lagu cabbiro isbeddellada ku yimaadda meelaha magnetic, heerkulka, qaab-dhismeedka molecular, isdhexgalka kiimikaad ama gariirka dhawaaqa.Polarizers waxaa loo isticmaalaa in lagu gudbiyo xaalad polarization gaar ah iyadoo la xannibayo dhammaan kuwa kale.Ilaysku wuxuu yeelan karaa toosan, wareeg ama elliptical polarization.
Habdhaqanka mawjadaha mawjadaha (sida taarikada kala badh, taarikada rukunka rubuca, iwm.) waxay ku xidhan tahay dhumucda crystal, dhererka hirarka iftiinka iyo isbeddelka tusaha refractive.Iyadoo si habboon loo dooranayo xiriirka ka dhexeeya cabbirradan, isbeddelka wajiga la xakameeyey ayaa lagu soo bandhigi karaa inta u dhaxaysa labada qaybood ee polarization ee mowjadda iftiinka, taas oo beddeleysa polarization-keeda.
Polarizers aflaanta khafiifka ah ee waxqabadka sare leh ayaa la soo saaray iyadoo la adeegsanayo tignoolajiyada daahan uumiga dhigaalka khafiifka ah ee casriga ah si loo helo waxqabadka ugu wanaagsan.Polarizers-yada waxaa lagu heli karaa daahan dahaarka ah ee labada dhinac ee polarizer-ka, ama daahan dahaarka ah ee dhinaca wax-gelinta ah iyo daahan tayo sare leh oo lakabyo badan oo ka hortag ah oo dhinaca wax soo saarka ah.
