Kev Nthuav Qhia Txog Qhov Muag Thoob Ntiaj Teb Shanghai (Shanghai Eyewear Exhibition, International Eyewear Exhibition) yog ib qho ntawm kev lag luam tsom iav thoob ntiaj teb loj tshaj plaws thiab tau lees paub hauv Suav teb, thiab tseem yog kev nthuav qhia tsom iav thoob ntiaj teb uas muaj cov npe nrov hauv Asia.
Lub Rooj Sib Tham Txog Kev Ua Koob Tsheej Thoob Ntiaj Teb Shanghai (Shanghai Eyewear Exhibition, International Eyewear Exhibition) tau muaj nyob rau hauv plaub lub tsev ua yeeb yam hauv Shanghai World Expo Exhibition Hall. Qhov chaw ua yeeb yam yog qhov chaw qub ntawm 2010 Shanghai World Expo, uas yog qhov chaw nruab nrab ntawm Shanghai thiab qhov chaw kub ntawm cov neeg, nyob hauv qhov zoo ntawm thaj chaw thiab cov chaw ua tiav.
Ntawm lawv, Hall 2 yog lub tsev rau cov khoom lag luam zam thoob ntiaj teb, thaum Hall 1, 3 thiab 4 yog qhov chaw rau cov tuam txhab tsom iav zoo tshaj plaws hauv Suav teb. Yuav kom txhawb nqa Tuam Tshoj cov tswv yim tsim tsom iav zoo tshaj plaws thiab cov khoom tshiab, tus neeg teeb tsa yuav teeb tsa thaj chaw tshwj xeeb ntawm "Cov Haujlwm Tsim Qauv" hauv chav nruab nrab ntawm pem teb hauv av, thiab teeb tsa Hall 4 ua "chaw muag khoom". Tsis tas li ntawd, Shanghai International Eyewear Exhibition (Shanghai Eyewear Exhibition, International Eyewear Exhibition) kuj yooj yim rau cov neeg yuav khoom xaj lawv cov khoom tsom iav nyiam ntawm qhov chaw.
Ntau yam ntawm cov khoom pov thawj
Txhua yam iav: Cov thav duab tsom iav, tsom iav dub, tsom iav, tsom iav sib cuag, tsom iav 3D, tsom iav digital, cov khoom siv kho qhov muag, cov tsom iav thiab cov tshuab tsim tsom iav, cov khoom siv tsom iav thiab cov khoom siv, cov khoom siv raw tsom iav, pwm, cov khoom siv kho qhov muag, cov tshuaj ntxuav tsom iav thiab cov tshuaj sib cuag, cov thawv tsom iav, cov cuab yeej kho mob qhov muag, cov khoom siv kho qhov muag, cov khoom siv hauv Hoobkas tsom iav, tsom iav qhov muag, cov khoom siv kuaj thiab kho amblyopia, cov ntawv xov xwm txog kev tshawb fawb thiab kev siv tshuab.

Lub rooj nthuav qhia no muaj 758 tus neeg nthuav qhia, suav nrog 158 tus neeg nthuav qhia thoob ntiaj teb los ntawm 18 lub tebchaws thiab thaj chaw thoob ntiaj teb. Ntawm lawv, muaj ntau dua 20 "lub ntsej muag tshiab" hauv Tsev khaws puav pheej thoob ntiaj teb, suav txog li 12%; Muaj ze li ntawm 80 tus neeg nthuav qhia tshiab hauv lub tsev hauv tebchaws, suav txog 15% ntawm tag nrho. Lub ntsej muag tshiab thiab cov phooj ywg qub, sib sau ua ke zoo siab!
Nrog thaj chaw ua yeeb yam ntau dua 70,000 square meters, ntau dua 10 hom khoom lag luam siab heev thiab cov txiaj ntsig thev naus laus zis xws li tsom iav hnub, iav tsom iav, iav qhov muag, cov cuab yeej thiab cov khoom siv, cov khoom siv sab nraud thiab cov software systems tau tso tawm tag nrho. Cov ntsiab lus "Future Vision" uas tsim tau zoo heev thiab cov chaw nyob hauv Expo Exhibition Center, dhau los ua lub tshuab cua rau tib neeg.
Thaum lub sijhawm 3 hnub ntawm kev nthuav qhia, lub koom haum thiab cov tuam txhab koom nrog tau tuav ze li ntawm 30 yam kev ua ub no ntawm ntau qhov sib txawv thaum lub sijhawm tib lub sijhawm, suav nrog kev nce qib tshiab hauv kev tiv thaiv thiab tswj myopia, kev txhais lus txoj cai tiv thaiv thiab tswj myopia, kev noj qab haus huv ntawm lub tebchaws, kev tso tawm tshiab ntawm thav duab thiab lens thiab ntau lwm yam ntsiab lus, cov ntsiab lus nplua nuj thiab ntxaws ntxaws, los pab cov neeg tuaj saib txaus siab rau kev nkag siab ib zaug ntawm cov thev naus laus zis tshiab thiab kev txhim kho kev lag luam ntawm kev ntsuas qhov muag.
Muaj ntau lub tuam txhab ua cov lens hauv tsev thiab txawv teb chaws tau koom nrog kev nthuav qhia.
Lub lens resin yog ib hom lens ua los ntawm cov khoom siv organic, sab hauv yog cov qauv polymer saw, txuas nrog peb-seem network qauv, cov qauv intermolecular yog qhov so, thiab qhov chaw ntawm cov saw molecular tuaj yeem tsim kev hloov pauv sib piv. Lub teeb transmittance yog 84% -90%, lub teeb transmittance yog qhov zoo, thiab lub lens resin optical muaj zog tiv taus kev cuam tshuam.

Lub teeb transmittance yog 84% -90%, lub teeb transmittance yog qhov zoo, thiab lub lens optical resin muaj zog tiv taus kev cuam tshuam.
Cov iav resin yog ib hom iav kho qhov muag ua los ntawm cov resin. Muaj ntau hom khoom siv, thiab piv rau cov iav iav, nws muaj nws cov txiaj ntsig tshwj xeeb:
1. Lub teeb. Cov iav resin dav dav yog 0.83-1.5, thiab iav kho qhov muag 2.27 ~ 5.95.
2, muaj zog tiv taus kev cuam tshuam. Qhov kev tiv taus kev cuam tshuam ntawm cov iav resin feem ntau yog 8 ~ 10kg / cm2, uas yog ntau zaus ntawm iav, yog li nws tsis yooj yim tawg, muaj kev nyab xeeb thiab ruaj khov.
3, lub teeb kis tau zoo. Hauv thaj chaw pom, qhov kev xa tawm ntawm cov iav resin zoo ib yam li iav. Thaj chaw infrared siab dua iav me ntsis; Hauv thaj chaw ultraviolet, qhov kev xa tawm txo qis thaum qhov wavelength txo qis, thiab lub teeb nrog qhov wavelength tsawg dua 0.3um yuav luag nqus tag.
4, tus nqi qis. Kev txhaj tshuaj molding lens, tsuas yog xav tau tsim cov pwm meej, tuaj yeem tsim tau ntau, txuag cov nqi ua thiab lub sijhawm.
5, tuaj yeem ua tau raws li qhov xav tau tshwj xeeb. Piv txwv li, kev tsim cov iav aspherical tsis nyuaj, thiab cov iav iav nyuaj ua.
Kev sib cav
Cov ntsuas refractive uas quav tau
Nws yog qhov sib piv ntawm lub kaum sab xis ntawm lub lens rau lub teeb pom kev thiab lub kaum sab xis ntawm lub teeb pom kev. Nws tus nqi feem ntau yog nruab nrab ntawm 1.49 thiab 1.74. Nyob rau tib theem, qhov siab dua ntawm qhov refractive index, qhov nyias dua lub lens, tab sis qhov siab dua ntawm qhov refractive index ntawm cov khoom, qhov hnyav dua nws cov dispersion.
Kev tiv thaiv kev khawb
Hais txog qib kev puas tsuaj rau lub teeb ci ntsa iab ntawm lub lens nto raws li kev ua ntawm lub zog sab nraud. Qhov khawb ntawm lub lens yog ib qho tseem ceeb uas cuam tshuam rau lub neej ua haujlwm thiab qhov pom ntawm lub lens. Tus nqi sib txhuam pos huab (Hs) feem ntau siv hauv Suav teb qhia tias nws tus nqi feem ntau yog ntawm 0.2-4.5, thiab qis dua qhov zoo dua. Txoj kev BAYER feem ntau siv hauv txawv teb chaws, thiab nws tus nqi yog ntawm 0.8-4, siab dua qhov zoo dua. Feem ntau hu ua cov iav resin tawv, kev tiv thaiv khawb zoo dua li cov iav resin dav dav.
Tus nqi txiav UV uas quav tau
Kuj hu ua tus nqi UV, nws yog ib qho cim qhia tseem ceeb los ntsuas qhov kev thaiv ntawm lub lens ultraviolet. Nws tus nqi yuav tsum ntau dua 315nm, feem ntau ntau dua 350nm thiab tsawg dua 400nm. Lub lens UV400, uas feem ntau hnov hauv cov khw muag khoom kho qhov muag, tuaj yeem thaiv tau zoo ultraviolet. Tsis tas li ntawd, nws tseem tuaj yeem ntxiv cov zaj duab xis tiv thaiv hluav taws xob rau lub lens resin.
Folding lub teeb transmittance
Qhov piv ntawm qhov ntau ntawm lub teeb uas lub lens tso tawm rau qhov ntau ntawm lub teeb uas nkag mus. Qhov siab dua qhov transmittance, qhov tseeb dua lub lens.
Tus lej abbe uas quav tau
Nws yog siv los qhia qhov piv txwv ntawm qhov muaj peev xwm ntawm cov khoom pob tshab, thiab siv tau los ua qhov siv rau qhov kev daws teeb meem ntawm cov xim qhuav ntawm lub teeb pom kev ntawm lub lens. Nws tus nqi yog nruab nrab ntawm 32 thiab 60, thiab qhov siab dua tus lej Abbe ntawm lub lens, qhov tsawg dua qhov kev cuam tshuam.
Kev tiv thaiv kev cuam tshuam
Hais txog lub zog kho tshuab ntawm lub lens kom tiv taus qhov cuam tshuam. Qhov kev tiv thaiv kev cuam tshuam ntawm cov iav lens resin muaj zog dua li cov iav lens iav, thiab txawm tias qee cov iav lens resin kuj tsis tawg.
Tseem muaj ntau yam zoo ntawm cov iav resin, yog tsis yog li ntawd ces nws yuav tsis yog cov iav siv ntau tshaj plaws tam sim no. Cov iav resin kuj tuaj yeem pleev xim rau, qhov plasticity yog qhov ruaj khov, zoo dua li lwm cov iav, tab sis qhov zoo ntawm cov iav resin tseem txawv heev, yog li thaum peb phim cov tsom iav, peb tseem yuav tsum xaiv kom zoo, kom xaiv tau cov tsom iav zoo rau peb.
