Shanghai International Eyewear Exhibition (Shanghai Eyewear Exhibition, International Eyewear Exhibition) yog ib qhov loj tshaj plaws thiab raug lees paub thoob ntiaj teb kev lag luam tsom iav thiab kev lag luam exhibitions hauv Suav teb, thiab tseem yog lub thoob ntiaj teb eyewear exhibition featuring nto moo hom nyob rau hauv Asia.
Shanghai International Eyewear Exhibition (Shanghai Eyewear Exhibition, International Eyewear Exhibition) tau muaj nyob rau hauv tag nrho plaub lub exhibition halls nyob rau hauv lub Shanghai World Expo Exhibition Hall.Lub chaw ua yeeb yam yog thawj qhov chaw ntawm 2010 Shanghai World Expo, uas yog qhov chaw ntawm Shanghai thiab qhov chaw kub ntawm cov neeg, tuav qhov zoo ntawm thaj chaw zoo thiab cov chaw ua tiav.
Ntawm lawv, Hall 2 yog lub thoob ntiaj teb zam lub tsev lag luam, thaum Hall 1, 3 thiab 4 haum rau Tuam Tshoj cov tuam txhab tsom iav zoo heev.Txhawm rau kom muaj txiaj ntsig zoo tshaj plaws ntawm Tuam Tshoj thawj chav kawm tsom iav tsim cov ntsiab lus thiab cov khoom lag luam tshiab, tus neeg tsim khoom yuav teeb tsa thaj chaw tshwj xeeb ntawm "Designer works" nyob rau hauv nruab nrab chav tsev hauv av, thiab teeb tsa Hall 4 ua "boutique Hall. ".Tsis tas li ntawd, Shanghai International Eyewear Exhibition (Shanghai Eyewear Exhibition, International Eyewear Exhibition) kuj yog qhov yooj yim rau cov neeg yuav khoom kom xaj lawv cov khoom muag muag muag ntawm qhov chaw.
Ntau yam ntawm cov khoom pov thawj
Txhua yam iav: Cov tsom iav tsom iav, looj tsom iav dub, lo ntsiab muag, tsom iav, 3D tsom iav, cov lo ntsiab muag digital, cov khoom siv kho qhov muag, tsom iav thiab lens ntau lawm tshuab, tsom iav qhov chaw thiab cov khoom siv, tsom iav raw khoom, pwm, cov khoom kho qhov muag, lens thiab tiv thaiv lub lens tu kev daws teeb meem, tsom iav qhov muag, cov cuab yeej kho mob ophthalmic, ophthalmic cov khoom lag luam, cov khoom siv tsom iav tsom iav, tsom iav tsom iav, cov khoom siv tshuaj ntsuam xyuas amblyopia thiab kho cov khoom siv, cov ntaub ntawv tshawb fawb txog kev tshawb fawb thiab kev lag luam, cov koom haum kev lag luam tsom iav, thiab lwm yam.
Cov cuab yeej tshwj xeeb rau cov tsom iav: cov khoom siv tsom iav, cov khoom siv kho qhov muag thiab cov khoom siv, cov khoom siv raw thiab cov khoom siv rau cov tsom iav, cov iav tiv thaiv thiab cov khoom siv kho qhov muag

Qhov kev nthuav qhia no muaj 758 tus neeg tuaj koom, suav nrog 158 tus neeg tuaj koom thoob ntiaj teb los ntawm 18 lub teb chaws thiab cheeb tsam thoob ntiaj teb.Ntawm lawv, muaj ntau dua 20 "lub ntsej muag tshiab" nyob rau hauv International tsev cia puav pheej, suav txog li 12%;Muaj ze li ntawm 80 tus neeg tuaj koom tshiab hauv lub tsev pavilion, suav txog 15% ntawm tag nrho.Cov ntsej muag tshiab thiab cov phooj ywg qub, zoo siab sib sau ua ke!
Nrog rau thaj tsam ntawm ntau tshaj 70,000 square meters, ntau tshaj 10 hom khoom thiab kev ua tau zoo xws li looj tsom iav dub, tsom iav qhov muag, lub qhov muag lo ntsiab muag, cov cuab yeej siv thiab cov khoom siv, cov khoom siv peripheral thiab software systems tau nthuav tawm tag nrho.Ua tib zoo tsim "Lub Zeem Muag Yav Tom Ntej" cov ntsiab lus kev teeb tsa thiab lub sijhawm-daim npav qhov chaw nyob thoob plaws hauv Expo Exhibition Center, dhau los ua huab cua vane rau tib neeg.
Thaum lub sij hawm 3-hnub exhibition, lub koom haum thiab cov koom haum koom tes tau tuav ze li ntawm 30 kev ua ub no ntawm txawv teev nyob rau hauv tib lub sij hawm, nrog rau qhov tseeb kev vam meej ntawm myopia tiv thaiv thiab tswj, myopia tiv thaiv thiab tswj txoj cai txhais lus, lub teb chaws pom kev noj qab haus huv, ncej thiab lens hom. kev tso tawm tshiab thiab ntau lwm cov ntsiab lus, cov ntsiab lus nplua nuj thiab cov ncauj lus kom ntxaws, los pab cov neeg tuaj saib kom txaus siab rau ib qho kev nkag siab ntawm kev siv thev naus laus zis thiab kev lag luam kev loj hlob ntawm optometry.
Ntau lub tuam txhab lag luam hauv tsev thiab txawv teb chaws tau koom nrog hauv kev nthuav qhia.
Resin lens yog ib hom lens uas ua los ntawm cov khoom siv organic, sab hauv yog cov qauv saw hlau polymer, kev sib txuas thiab peb-seem lub network qauv, cov qauv ntawm cov qauv sib txawv yog qhov zoo, thiab qhov chaw nruab nrab ntawm cov saw hlau molecular tuaj yeem tsim kev sib txawv txav.Lub teeb xa hluav taws xob yog 84% -90%, lub teeb xa hluav taws xob yog qhov zoo, thiab lub lens optical resin muaj qhov cuam tshuam zoo.
Resin lo ntsiab muag yog ib yam khoom siv organic, sab hauv yog cov qauv saw hlau polymer, kev sib txuas thiab peb-seem lub network qauv, cov qauv kev sib tshuam yog qhov zoo, thiab qhov chaw nruab nrab ntawm cov saw hlau molecular tuaj yeem tsim cov kev sib txawv txav.Lub teeb xa hluav taws xob yog 84% -90%, lub teeb xa hluav taws xob yog qhov zoo, thiab lub lens optical resin muaj qhov cuam tshuam zoo.
Resin lens yog ib hom optical lens ua los ntawm resin.Muaj ntau ntau yam khoom siv, thiab piv nrog cov iav lo ntsiab muag, nws muaj nws qhov tshwj xeeb zoo:
1. Lub teeb.Cov lo ntsiab muag dav dav yog 0.83-1.5, thiab iav optical 2.27 ~ 5.95.
2, muaj zog cuam tshuam tsis kam.Qhov cuam tshuam ntawm cov iav lo ntsiab muag feem ntau yog 8 ~ 10kg / cm2, uas yog ob peb zaug ntawm iav, yog li nws tsis yooj yim tawg, nyab xeeb thiab ruaj khov.
3, lub teeb kis tau zoo.Nyob rau hauv cheeb tsam pom, qhov transmittance ntawm resin lens zoo ib yam li cov iav.Infrared cheeb tsam, me ntsis siab dua iav;Nyob rau hauv cheeb tsam ultraviolet, qhov kev xa tawm tau txo qis thaum lub wavelength txo, thiab lub teeb nrog lub wavelength tsawg dua 0.3um yuav luag tag nrho absorbed.
4, tus nqi qis.Txhaj tshuaj molding lo ntsiab muag, tsuas yog yuav tsum tau tsim cov pwm meej, tuaj yeem ua ntau yam, txuag cov nqi thiab sijhawm.
5, tuaj yeem ua tau raws li qhov xav tau tshwj xeeb.Piv txwv li, kev tsim cov lo ntsiab muag aspherical tsis yooj yim, thiab cov iav lo ntsiab muag tsis yooj yim ua.
Kev sib cav
Folded refractive index
Nws yog sine ratio ntawm kis lub teeb lub kaum sab xis ntawm lub lens mus rau qhov teeb meem teeb pom kev zoo thiab qhov teeb meem teeb lub kaum sab xis.Nws tus nqi yog feem ntau ntawm 1.49 thiab 1.74.Nyob rau tib lub degree, qhov siab dua qhov refractive index, lub lens yog thinner, tab sis qhov siab dua qhov refractive index ntawm cov khoom, qhov hnyav dua nws dispersion.
Folding kuj rau khawb
Hais txog qhov kev puas tsuaj rau lub teeb kis ntawm lub lens nto nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam.Kev khawb ntawm lub lens yog ib qho tseem ceeb uas cuam tshuam rau lub neej kev pabcuam thiab kev pom ntawm lub lens.Feem ntau siv kev sib txhuam fog tus nqi (Hs) hauv Suav teb qhia tias nws tus nqi feem ntau yog nyob nruab nrab ntawm 0.2-4.5, thiab qhov qis dua qhov zoo dua.Txoj kev BAYER feem ntau siv nyob rau hauv txawv teb chaws, thiab nws cov nqi yog nyob nruab nrab ntawm 0.8-4, qhov siab dua qhov zoo dua.Feem ntau hu ua hardened resin lo ntsiab muag, khawb kuj zoo dua li cov lo ntsiab muag dav dav.
Folding UV cutoff tus nqi
Kuj tseem hu ua UV tus nqi, nws yog ib qho tseem ceeb qhia los ntsuas qhov zoo ntawm kev thaiv cov hluav taws xob ultraviolet ntawm lub lens.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 khw muag khoom kho qhov muag, tuaj yeem thaiv cov hluav taws xob ultraviolet.Tsis tas li ntawd, nws tseem tuaj yeem ntxiv cov duab hluav taws xob tiv thaiv rau lub lens resin.
Folding lub teeb transmittance
Qhov piv ntawm tus nqi ntawm lub teeb projected los ntawm lub lens rau tus nqi ntawm lub teeb teeb meem.Qhov siab dua qhov transmittance, lub lens ntau dua.
Folded abbe tus lej
Nws yog siv los qhia qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov muaj peev xwm ntawm cov khoom pob tshab, thiab tuaj yeem siv los ua qhov kev daws teeb meem ntawm cov xim qhuav ntawm lub teeb pom kev ntawm lub lens.Nws tus nqi yog nyob nruab nrab ntawm 32 thiab 60, thiab qhov siab dua ntawm Abbe tus naj npawb ntawm lub lens, qhov cuam tshuam tsawg dua.
Folding tsis kam rau kev cuam tshuam
Hais txog lub zog txhua yam ntawm lub lens kom tiv taus qhov cuam tshuam.Qhov cuam tshuam ntawm cov lo ntsiab muag resin muaj zog dua li cov iav lo ntsiab muag, thiab txawm tias qee qhov lo ntsiab muag resin tsis tawg.
Tseem muaj ntau cov txiaj ntsig ntawm cov lo ntsiab muag resin, txwv tsis pub nws yuav tsis yog siv lo ntsiab muag tshaj plaws tam sim no.Resin lo ntsiab muag kuj tuaj yeem coated, cov yas yog qhov muaj zog, zoo dua li lwm cov lo ntsiab muag, tab sis qhov zoo ntawm cov lo ntsiab muag resin tseem txawv heev, yog li thaum peb sib tw tsom iav, peb tseem yuav tsum tau ua tib zoo xaiv, thiaj li xaiv cov iav zoo. rau peb.
