Isizukulwane esidala sodokotela bamehlo sasivame ukubuza ukuthi banawo yini amalensi engilazi noma acwebezelayo, futhi saklolodela amalensi eresin esivame ukuwagqoka namuhla. Ngoba lapho beqala ukuthintana namalensi e-resin, ubuchwepheshe bokumboza bamalensi e-resin abuzange buthuthukiswe ngokwanele, futhi kwaba nobubi obufana nokungagugi futhi kulula ukushiya amabala. Ngaphezu kwalokho, abakhiqizi abaningi nabathengisi bane-backlog yamalensi engilazi adinga ukuthengiswa, ngakho-ke ukushiyeka kwamalensi e-resin kuye kwaba ihaba isikhathi esithile.
Amalensi engilazi anezinzuzo zokungagugi kanye nenkomba ephezulu ye-refractive. Kodwa isisindo kanye nokuba ntekenteke kwayo kwabangela ukuba ithathelwe indawo amalensi e-resin. Ngokuthuthuka kwesayensi nobuchwepheshe, ubuchwepheshe bokumboza obuthuthukiswe imboni yokukhiqiza i-spectacle lens buxazulule izinkinga eziningi ekuqaleni kokusungulwa kwamalensi e-resin. Lesi sihloko sizokunikeza isingeniso esifushane sokumboza ama-lens e-spectacle, ukuze ukwazi ukuqonda ngokunembayo ukumbozwa kwamalensi owagqokayo kanye nomlando wabo wokuthuthuka.
Ngokuvamile sinezinhlobo ezintathu zamalensi, okuyizimbotshana ezingagugi, i-anti-reflection, ne-anti-fouling. Izendlalelo ezihlukene zokumboza zisebenzisa izimiso ezahlukene. Siyazi ngokujwayelekile ukuthi umbala wangemuva wawo womabili amalensi e-resin namalensi engilazi awunambala, nemibala efiphele kumalensi ethu ajwayelekile ilethwa yilezi zendlalelo.
Ifilimu engagqoki
Uma kuqhathaniswa namalensi engilazi (ingxenye eyinhloko yengilazi i-silicon dioxide, okuwumsebenzi wezinto ezingaphili), ingaphezulu lamalensi okubuka enziwe ngezinto eziphilayo kulula ukukugqoka. Kunezinhlobo ezimbili zokuklwebheka ebusweni bamalensi embukwane angabonwa ngokubheka ngesibonakhulu. Enye yenziwe ngesihlabathi esincane namatshe. Nakuba imihuzuko ingashoni futhi mincane, ogqokile akathinteki kalula, kodwa lapho imihuzuko enjalo inqwabelana ngezinga elithile, isenzakalo esihlakazeka sokukhanya esibangelwa imihuzuko sizothinta kakhulu umbono womuntu oyifakile. Kukhona nokuklwebheka okukhulu okubangelwa amatshe amakhulu noma ezinye izinto eziqinile. Lolu hlobo lokuklwebheka lujulile futhi i-periphery ilukhuni. Uma ukuklwebheka kumaphakathi nelensi, kuzophazamisa ukubona komuntu oyifakile. Ngakho-ke, ifilimu yokumelana nokugqoka yaba khona.
Ifilimu evimbela ukugqokwa iye yabhekana nezizukulwane ezimbalwa zentuthuko. Ekuqaleni, yaqala ngawo-1970. Ngaleso sikhathi, kwakukholelwa ukuthi ingilazi yayingagugi ngenxa yokuqina kwayo okuphezulu, ngakho-ke ukuze wenze i-resin lens ibe nokumelana okufanayo kokugqoka, kwasetshenziswa indlela yokugcoba i-vacuum. , ungqimba lwe-quartz lubekwe phezu kwe-organic lens. Kodwa-ke, ngenxa yama-coefficients ahlukene wokwandisa okushisayo wezinto ezimbili, ukugqoka kulula ukuwa futhi ku-brittle, futhi umphumela wokumelana nokugqoka awumuhle. Isizukulwane esisha sobuchwepheshe sizovela njalo eminyakeni eyishumi esikhathini esizayo, futhi i-coating yamanje engavimbeli ungqimba lwefilimu oluxubile lwe-organic matrix kanye nezinhlayiya ezingaphili. Owokuqala uthuthukisa ukuqina kwefilimu evimbela ukugqoka, futhi lokhu kwandisa ukuqina. Inhlanganisela enengqondo yakho kokubili ifinyelela umphumela omuhle wokungagugi.
I-anti-reflection coating
Amalensi esiwagqokayo afana nezibuko eziyisicaba, futhi isigameko esikhanyayo ebusweni bamalensi ezingilazi sizophinde sibonise. Kwezinye izimo ezithile, ukubonakaliswa okukhiqizwa ama-lens ethu akuthinti kuphela umuntu ogqokile kodwa futhi nomuntu obuka ogqokile, futhi ngezikhathi ezibucayi, lesi simo singaholela ezenzakalweni ezinkulu zokuphepha. Ngakho-ke, ukuze kugwenywe ukulimala okubangelwa yilesi simo, amafilimu aphikisayo athuthukisiwe.
Izingubo zokulwa ne-reflection zisekelwe ekuguquguqukeni nasekuphazamisekeni kokukhanya. Ukukubeka kalula, ifilimu ephikisana ne-reflection imbozwe phezu kwe-lens ye-spectacle, ukuze ukukhanya okuveziwe okukhiqizwe endaweni yangaphambili nangemuva yefilimu kuphazamise omunye nomunye, ngaleyo ndlela kususe ukukhanya okuveziwe futhi kuzuze umphumela wefilimu. anti-reflection.
Ifilimu ephikisayo
Ngemuva kokuthi i-lens surface imbozwe nge-anti-reflection coating, kulula kakhulu ukushiya amabala. Lokhu kuzonciphisa kakhulu "ikhono lokuphikisa" kanye nekhono elibonakalayo le-lens. Isizathu salokhu ukuthi ungqimba lwe-anti-reflection coating lunesakhiwo se-microporous, ngakho-ke uthuli olucolile kanye namabala kawoyela ashiywa kalula endaweni ye-lens. Isixazululo salesi senzakalo ukugqoka ifilimu ephezulu phezulu kwefilimu ephikisana ne-reflection, futhi ukuze kunganciphisi ikhono lefilimu ephikisayo, ukuqina kwe-anti-fouling yalesi sendlalelo kudinga ukuba kube mncane kakhulu.
Ilensi enhle kufanele ibe nefilimu eyinhlanganisela eyakhiwe yilezi zendlalelo ezintathu, futhi ukuze kuthuthukiswe ikhono elimelene nokubukisa, kufanele kube nezingqimba eziningi zamafilimu aphikisayo abekwe phezulu. Ngokuvamile, ubukhulu bongqimba obungagugi bungu-3~5um, ifilimu ye-multilayer anti-reflection imayelana no-0.3~0.5um, kanti ifilimu encane kakhulu evimbela ukungcola ingu-0.005um~0.01um. Ukuhleleka kwefilimu kusuka ngaphakathi kuya ngaphandle kuyi-coating-resistant-resistant, i-multi-layer anti-reflection coating kanye nefilimu ye-anti-fouling.
