Cov lus qhia ntxaws ntxaws rau zaj duab xis polarizing ntawm polarizing microscope
Lub luag haujlwm tseem ceeb ntawm lub phaj polarizing ntawm lub tshuab tsom iav polarizing yog los 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 lub polarizer yog hloov lub teeb ntuj dhau los ntawm nws mus 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 phaj yog ib yam khoom uas polarizes tsis polarized ntuj lub teeb thiab hloov mus rau hauv polarized teeb. Ua ke nrog cov yam ntxwv sib tw ntawm cov kua siv lead ua kua molecules, nws tswj qhov kev pom ntawm lub teeb, yog li txhim kho qhov kev xa tawm thiab saib lub kaum sab xis, thiab tsim cov haujlwm tiv thaiv glare. Nws yog ib qho khoom tseem ceeb heev nyob rau hauv cov khoom siv raw khoom ntawm lub vaj huam sib luag, thiab suav txog li 10 feem pua ntawm cov khoom siv raw ntawm LCDTV.
Polarizers yog cais los ntawm kev ua haujlwm: transmissive polarizers, reflective polarizers, semi transmissive polarizers, semi reflective polarizers, them polarizers
Polarizers yog cais los ntawm txoj kev staining:
Iodine raws polarizer: Nws yog ib qho yooj yim kom tau txais cov khoom siv kho qhov muag nrog kev sib kis siab thiab polarization, tab sis nws muaj peev xwm tiv taus kub thiab av noo tsis zoo.
Dye raws polarizer: Nws tsis yog yooj yim kom tau txais kev xa tawm siab thiab polarization optical zog, tab sis nws muaj kev tiv thaiv zoo rau kub thiab av noo.
Kev sib xyaw ntawm polarizer
Qhov ntxov tshaj plaws polarizers feem ntau muaj PVA zaj duab xis nyob rau hauv nruab nrab uas tuaj yeem tsim lub teeb polarized, thiab tom qab ntawd TAV tiv thaiv zaj duab xis sib xyaw rau ob sab. Txhawm rau pab txhawb kev siv thiab ua tiav cov teebmeem kho qhov muag sib txawv, cov chaw muag khoom polarizer yuav tsum ua raws li cov kev cai ntawm LCD cov chaw tsim khoom, thiab tom qab ntawd siv cov nplaum nplaum rau ob sab, ua raws li cov yeeb yaj kiab tso tawm. Qhov no polarizer yog ib qho TN zoo tib yam tag nrho kis tau tus mob polarizer. Yog tias ib txheej ntawm cov yeeb yaj kiab tso tawm raug tshem tawm thiab lwm txheej ntawm cov yeeb yaj kiab uas muaj qhov sib xyaw ua ke, nws yog qhov feem ntau pom cov polarizer.
Lub siab rhiab nplaum siv yog qhov kub-kub thiab noo noo-resistant siab rhiab nplaum nplaum, thiab PVA raug rau tshwj xeeb immersion kev kho mob (dye series khoom), uas ua rau ib tug dav kub polarizer; Los ntawm kev ntxiv cov khoom xyaw uas tiv thaiv ultraviolet rays los ntawm kev siv lub siab rhiab nplaum nplaum, UV resistant polarizer tuaj yeem ua tau; Los ntawm kev sib koom ua ke birefringent optical them nyiaj zaj duab xis ntawm qhov chaw xa khoom, lub polarizer rau STN tuaj yeem ua tau; Los ntawm kev sib txuas cov yeeb yaj kiab lub teeb rau ntawm qhov kev sib kis ntawm cov substrate, lub kaum sab xis dav polarizer tuaj yeem tsim tau; Xim cov nplaum nplaum, PVA zaj duab xis, lossis TAC zaj duab xis siv yog hu ua xim polarizer. Qhov tseeb, nrog kev txhim kho txuas ntxiv ntawm cov khoom siv LCD tshiab, muaj ntau thiab ntau hom polarizers.
