Khoom nta
1. Kev faib tawm thiab lub hauv paus ntsiab lus ntawm photochromic lens
Photochromic lens raws li lub lens discoloration qhov chaw tau muab faib ua photochromic lens (hu ua "base change") thiab membrance layer discoloration lens (hu ua "film change") ob yam.
Lub substrate photochromic lens yog ntxiv tshuaj lom neeg ntawm silver halide nyob rau hauv lub lens substrate.Los ntawm cov tshuaj tiv thaiv ionic ntawm silver halide, nws yog decomposed rau hauv nyiaj thiab halide xim rau lub lens nyob rau hauv lub teeb muaj zog stimulation.Tom qab lub teeb tsis muaj zog, nws tau muab tso rau hauv cov nyiaj halide kom cov xim sib dua.Cov txheej txheem no feem ntau yog siv rau iav photochroimc lens.
Zaj duab xis hloov lub lens tshwj xeeb yog kho nyob rau hauv cov txheej txheem lens txheej.Piv txwv li, spiropyran tebchaw yog siv rau high-speed spin txheej rau ntawm qhov chaw ntawm lub lens.Raws li kev siv ntawm lub teeb thiab ultraviolet lub teeb, cov qauv molecular nws tus kheej tuaj yeem hloov mus rau thiab tawm kom ua tiav cov txiaj ntsig ntawm kev hla lossis thaiv lub teeb.
2. Photochromic lens nta
(1) xim hloov ceev
Qhov ceev ntawm kev hloov xim yog ib qho tseem ceeb rau xaiv cov xim hloov lens.Lub lens hloov xim sai dua, qhov zoo dua, piv txwv li, los ntawm qhov tsaus ntuj sab hauv tsev mus rau qhov kaj sab nraum zoov, qhov kev hloov xim nrawm dua, txhawm rau txhawm rau txhawm rau tiv thaiv lub teeb muaj zog / ultraviolet puas rau lub qhov muag.
Feem ntau hais lus, zaj duab xis xim hloov tshuab yog nrawm dua li substrate xim hloov tshuab.Piv txwv li, cov txheej txheem tshiab ntawm cov xim hloov xim, cov khoom siv photochromic siv spiropyranoid tebchaw, uas muaj cov lus teb zoo dua lub teeb, siv cov qauv molecular ntawm nws tus kheej thim rov qab qhib thiab kaw kom ua tiav los ntawm lossis thaiv cov nyhuv ntawm lub teeb, yog li hloov xim sai dua.
(2) xim uniformity
Xim uniformity yog hais txog lub uniformity ntawm lub lens xim nyob rau hauv tus txheej txheem ntawm kev hloov ntawm lub teeb mus rau tsaus los yog los ntawm tsaus mus rau lub teeb.Qhov ntau hom kev hloov xim, qhov zoo dua qhov hloov xim lens.
Qhov zoo tshaj photochromic ntawm lub substrate ntawm cov tsoos lo ntsiab muag yog cuam tshuam los ntawm lub thickness ntawm ntau qhov chaw ntawm lub lens.Vim tias qhov chaw nruab nrab ntawm lub lens yog nyias thiab lub periphery yog tuab, lub hauv paus cheeb tsam ntawm lub lens hloov xim qeeb dua qhov periphery, thiab lub qhov muag panda yuav tshwm sim.Thiab cov zaj duab xis txheej xim hloov lub lens, kev siv cov txheej txheem kev kub ceev spin txheej, xim hloov zaj duab xis txheej txheej txheej spin txheej ua rau xim hloov ntau yam.
(3) Kev pab lub neej
Kev hloov xim xim lub lens kev pab cuam lub neej nyob rau hauv 1-2 xyoos los yog li ntawd, zoo li lub lens nyob rau hauv lub rotation txheej xim txheej yuav txhim kho txheej txheej, ntxiv rau cov xim hloov cov ntaub ntawv - spiropyranoid compound nws tus kheej kuj muaj zoo lub teeb stability, xim hloov ua hauj lwm ntev, yooj yim. tuaj yeem ncav cuag ntau tshaj ob xyoos.
3.Dab tsi yog qhov zoo ntawm cov lo ntsiab muag grey?
Yuav nqus tau infrared rays thiab 98% ultraviolet rays.Qhov zoo tshaj plaws ntawm grey lo ntsiab muag yog tias nws yuav tsis hloov cov xim qub ntawm qhov chaw vim yog lub lens, thiab qhov txaus siab tshaj plaws yog tias nws tuaj yeem txo cov teeb pom kev zoo.Grey lo ntsiab muag tuaj yeem nqus tau cov xim spectrum sib npaug, yog li qhov xwm txheej tsuas yog tsaus, tab sis yuav tsis muaj qhov txawv xim txawv, qhia qhov tseeb ntawm qhov xwm txheej.Nyob rau hauv nruab nrab xim system, nyob rau hauv txoj kab nrog kev siv ntawm tag nrho cov pab pawg neeg.
4. Qhov txawv ntawm HC, HMC thiab SHC yog dab tsi?
| Txheej tawv | AR txheej / Hard txheej txheej | Super hydrophobic txheej |
| ua rau lub lens uncoated nyuaj thiab tsub kom lub abrasion kuj | tsub kom lub transmittance ntawm lub lens thiab txo cov reflections nto | ua rau lub lens waterproof, antistatic, anti plam thiab roj kuj |
