POL inapangidwa ndi Edwin H. Land, yemwe anayambitsa kampani ya American Polaroid, mu 1938. Masiku ano, ngakhale kuti pakhala pali kusintha kochuluka kwa njira zopangira ndi zipangizo, mfundo zoyambirira za kupanga ndi zipangizo zidakali zofanana ndi zomwezo. nthawi.
Kugwiritsa ntchito POL:
Mtundu wa ntchito ya POL:
Wamba
Chithandizo cha Anti Glare (AG: Anti Glare)
HC: Kuphimba Kwambiri
Anti reflective treatment/low reflective treatment (AR/LR)
Anti static
Anti Smudge
Brightening Film Treatment (APCF)
Mtundu wa utoto wa POL:
Iodine POL: Masiku ano, PVA yophatikizidwa ndi molekyulu ya ayodini ndiyo njira yayikulu yopangira POL.PVA mlingo alibe bidirectional mayamwidwe mayamwidwe, kudzera mu ndondomeko utoto, magulu osiyanasiyana a kuwala kowoneka amayamwa ndi kuyamwa ayodini molekyulu 15- ndi 13-.Kuchuluka kwa molekyulu ya ayodini 15- ndi 13- kumapanga imvi yopanda ndale ya POL.Ili ndi mawonekedwe owoneka bwino a transmittance apamwamba komanso polarization yayikulu, koma kuthekera kwa kutentha kwambiri komanso kukana kwa chinyezi sikuli bwino.
POL yochokera ku utoto: Imatengera kwambiri utoto wachilengedwe wokhala ndi dichroism pa PVA, ndikufalikira mwachindunji, ndiye kuti imakhala ndi polarizing.Mwanjira iyi, sizingakhale zophweka kupeza mawonekedwe a kuwala kwapamwamba kwambiri komanso polarization yapamwamba, koma kuthekera kwa kutentha kwapamwamba komanso kukana kwa chinyezi kudzakhala bwino.
