POL tau tsim los ntawm Edwin H. Land, tus tsim ntawm American Polaroid tuam txhab, nyob rau hauv 1938. Niaj hnub no, txawm hais tias muaj ntau yam kev txhim kho nyob rau hauv ntau lawm cov tswv yim thiab cov cuab yeej siv, cov hauv paus ntsiab lus ntawm cov txheej txheem tsim thiab cov ntaub ntawv tseem yog tib yam li ntawm qhov ntawd. sij hawm.
Daim ntawv thov ntawm POL:
Hom kev ua haujlwm ntawm POL:
Ib txwm
Anti Glare Kev Kho Mob (AG: Anti Glare)
HC: Hard Txheej
Kev tiv thaiv kev cuam tshuam / kev kho qis qis (AR / LR)
Anti Static
Anti Smudge
Brightening Film Treatment (APCF)
Hom dyeing ntawm POL:
Iodine POL: Niaj hnub no, PVA ua ke nrog iodine molecule yog txoj hauv kev tseem ceeb ntawm kev tsim POL.PVA koob tshuaj tsis muaj bidirectional absorption kev ua tau zoo, los ntawm cov txheej txheem dyeing, sib txawv bands ntawm pom lub teeb yog absorbed los ntawm absorbing iodine molecule 15- thiab 13-.Qhov sib npaug ntawm absorbing iodine molecule 15- thiab 13- ua rau nruab nrab grey ntawm POL.Nws muaj cov yam ntxwv kho qhov muag ntawm kev xa tawm siab thiab siab polarization, tab sis muaj peev xwm ntawm qhov kub thiab txias tsis kam thiab cov av noo siab tsis zoo.
Dye-based POL: Nws yog tsuas yog nqus cov organic dyes nrog dichroism ntawm PVA, thiab txuas ncaj qha, ces nws yuav muaj cov khoom polarizing.Nyob rau hauv txoj kev no, nws yuav tsis yooj yim kom tau txais cov yam ntxwv kho qhov muag ntawm kev xa tawm siab thiab siab polarization, tab sis muaj peev xwm ntawm qhov kub thiab txias tsis kam thiab cov av noo siab yuav zoo dua.
