Cov lus qhia ntxaws ntxaws rau polarizers rau polarizing microscopes
Lub luag haujlwm tseem ceeb ntawm lub phaj polarizing ntawm lub tshuab tsom iav polarizing yog hloov lub teeb tsis muaj polarized rau hauv lub teeb polarized, tso cai rau lub teeb perpendicular mus rau qhov hluav taws xob hluav taws xob kom dhau mus, tso cai rau LCD vaj huam sib luag los tso saib cov duab ib txwm. Lub luag haujlwm tseem ceeb ntawm polarizer yog tig lub teeb ntuj uas dhau los ntawm polarizer rau hauv lub teeb polarized. Polarizer yog daim ntawv zoo li cov khoom siv kho qhov muag uas tsim thiab pom lub teeb pom kev zoo. Polarizer yog cov khoom tseem ceeb uas cuam tshuam rau cov nyhuv ntawm cov ntxaij vab tshaus LCD.
Polarizing daim hlau polarize ntuj lub teeb yam tsis muaj polarity thiab hloov nws mus rau hauv lub teeb polarized. Ua ke nrog cov yam ntxwv sib tw ntawm cov kua siv lead ua kua molecules, nws tswj xyuas seb lub teeb puas dhau los, yog li ua kom lub teeb xa mus thiab saib lub kaum sab xis ntau, thiab tsim los tiv thaiv glare thiab lwm yam haujlwm. , yog ib yam khoom tseem ceeb heev nyob rau hauv cov khoom siv raw khoom ntawm cov vaj huam sib luag, thiab suav txog li 10% ntawm LCDTV raw khoom nqi.
Polarizers yog cais los ntawm kev ua haujlwm: transmissive polarizer, reflective polarizer, semi-transmissive thiab semi-reflective polarizer, them nyiaj polarizer
Polarizers raug cais raws li txoj kev dyeing:
Iodine-raws li polarizer: Nws yog ib qho yooj yim kom tau txais cov khoom siv kho qhov muag ntawm kev xa tawm siab thiab siab polarization degree, tab sis nws muaj peev xwm tiv taus kub thiab av noo tsis zoo.
Dye-raws li polarizer: Nws tsis yog yooj yim kom tau txais cov khoom siv kho qhov muag ntawm kev xa tawm siab thiab siab polarization degree, tab sis nws muaj kev tiv thaiv zoo rau kub thiab av noo.
Kev sib xyaw ntawm polarizer
Cov polarizers ntxov tshaj plaws yog tsim los ntawm PVA zaj duab xis uas tuaj yeem tsim lub teeb polarized nyob rau hauv nruab nrab, thiab tom qab ntawd sib xyaw nrog TAV cov yeeb yaj kiab tiv thaiv ntawm ob sab. Txhawm rau pab txhawb kev siv thiab tau txais cov teebmeem sib txawv, cov chaw muag khoom polarizer, ntawm qhov kev thov ntawm LCD manufacturers, lub tsho tiv no ob sab nrog lub siab-rhiab nplaum nplaum thiab tom qab ntawd npog lawv nrog cov yeeb yaj kiab tso tawm. Hom polarizer no yog TN zoo tib yam polarizer kuv pom feem ntau. Tag nrho kis tau tus mob polarizer. Yog tias koj tshem tawm ib txheej ntawm cov yeeb yaj kiab tso tawm thiab ntxiv ib txheej ntawm cov yeeb yaj kiab, nws yuav yog qhov feem ntau pom cov polarizer.
Lub siab-rhiab nplaum nplaum siv yog kub-resistant thiab noo noo-pov thawj siab-rhiab nplaum nplaum, thiab PVA yog tshwj xeeb dipped (dye series khoom). Cov polarizer ua yog qhov dav-kub polarizer; ntxiv thaiv cov neeg ua haujlwm rau lub siab-rhiab nplaum nplaum siv Cov khoom siv uas tso cai rau cov kab hluav taws xob ultraviolet dhau los tuaj yeem ua rau cov tshuaj tiv thaiv UV polarizers; los ntawm kev sib xyaw ua ke ntawm birefringent optical them nyiaj rau zaj duab xis ntawm thawj kis zaj duab xis, lub polarizer rau STN tuaj yeem ua tau; los ntawm kev sib xyaw ua ke ntawm cov yeeb yaj kiab lub teeb rau ntawm cov yeeb yaj kiab thawj kis tau tus mob, nws tuaj yeem ua kom pom lub kaum sab xis dav lossis pom lub kaum ntse ntse polarizer; xim lub siab-rhiab nplaum nplaum, PVA zaj duab xis lossis TAC zaj duab xis siv los tsim cov xim polarizer. Qhov tseeb, nrog kev txhim kho txuas ntxiv ntawm cov khoom siv LCD tshiab, muaj ntau thiab ntau hom polarizers.
