Isizukulwana esidala soogqirha bamehlo sasihlala sibuza ukuba banayo na iilensi zeglasi okanye zekristale, kwaye bahlekisa ngeelensi zeresin esizinxibayo namhlanje. Kuba xa beqala ukudibana neelensi zeresin, itekhnoloji yokugquma iilensi zeresin ayizange iphuhliswe ngokwaneleyo, kwaye kukho izinto ezingeloncedo njengokunganxibi kwaye kulula ukushiya amabala. Ukongeza, abaninzi abavelisi kunye nabathengisi bane-backlog yeelensi zeglasi ezifuna ukuthengiswa, ngoko ke ukusilela kweelensi ze-resin kuye kwabaxwa kangangexesha elithile.
Iilensi zeglasi zineenzuzo zokuxhathisa ukunxitywa kunye nesalathiso esiphezulu se-refractive. Kodwa ubunzima kunye nobuthathaka bayo kwabangela ukuba ithatyathelwe indawo ziilensi zentlaka. Ngenkqubela phambili yesayensi kunye neteknoloji, iteknoloji yokugquma ephuhliswe yimboni yokuvelisa i-lens ye-spectacle iye yasombulula iingxaki ezininzi ekuqaleni kokuveliswa kweelensi ze-resin. Eli nqaku liza kukunika intshayelelo emfutshane yokugquma iilensi zokubukela, ukuze ukwazi ukuqonda ngokuthe ngqo iilensi ozinxibayo kunye nembali yazo yophuhliso.
Ngokuqhelekileyo sineentlobo ezintathu zeelensi zokugquma, ezizezi, ukugquma okunganxitywanga, ukugquma okuchasayo, kunye nokwaleka okuchasayo. Izaleko zokugquma ezahlukeneyo zisebenzisa imigaqo eyahlukeneyo. Siyazi ngokubanzi ukuba umbala ongasemva wazo zombini iilensi zeresin kunye neelensi zeglasi azinambala, kwaye imibala engacacanga kwiilensi zethu ngokubanzi iziswa zezi maleko.
Ifilimu enganxibiyo
Xa kuthelekiswa neeglasi zeglasi (inxalenye ephambili yeglasi yi-silicon dioxide, eyi-inorganic material), i-surface ye-spectacle lens eyenziwe ngezinto eziphilayo kulula ukunxiba. Kukho iindidi ezimbini zemikrwelo kumphezulu weelensi zokubukela ezinokubonwa ngokujongwa ngemicroscope. Enye yenziwe ngesanti encinci kunye negrabile. Nangona imikrwelo ingekho nzulu kwaye incinci, umntu oyinxibileyo akachaphazeleki lula, kodwa xa imikrwelo enjalo iqokelelana ukuya kuthi ga kwinqanaba elithile , isiganeko sokusasaza ukukhanya kwesiganeko esibangelwa yimikrwelo siya kuchaphazela kakhulu umbono womfaki. Kukwakho nomkrwelo omkhulu obangelwa yigrabile enkulu okanye ezinye izinto eziqinileyo. Olu hlobo lomkrwelo lunzulu kwaye iperiphery irhabaxa. Ukuba umkrwelo usembindini welensi, oko kuya kuchaphazela umbono womntu oyinxibileyo. Ke ngoko, ifilimu enganyangekiyo yokunxiba yavela.
Ifilimu yokumelana nokunxiba iye yafumana izizukulwana ezininzi zophuhliso. Ekuqaleni, yaqala ngo-1970. Ngelo xesha, kwakukholelwa ukuba iglasi yayingagugi ngenxa yobunzima bayo obuphezulu, ngoko ke ukwenzela ukuba i-lens ye-resin ibe nokuchasana okufanayo kokunxiba, indlela yokugqoka i-vacuum yayisetyenziswa. , uluhlu lwezinto ze-quartz zifakwe phezu kwendawo ye-organic lens. Nangona kunjalo, ngenxa yee-coefficients ezahlukeneyo zokwandiswa kwe-thermal yezinto ezimbini, ukugubungela kulula ukuwa kunye nokuphuka, kwaye umphumo wokumelana nokunxiba awulungile. Isizukulwana esitsha setekhnoloji siya kubonakala rhoqo kwiminyaka elishumi kwixesha elizayo, kwaye i-coat-resistant coating yangoku ngumaleko wefilimu oxutyiweyo we-organic matrix kunye namasuntswana angabonakaliyo. Owangaphambili uphucula ukuqina kwefilimu engagugiyo, kwaye okokugqibela kwandisa ubunzima. Ukudibanisa okufanelekileyo kwezi zibini kufezekisa umphumo ofanelekileyo wokunxiba.
I-anti-reflection coating
Iilensi esizinxibayo ziyafana nezibuko ezicaba, kwaye isiganeko sokukhanya kumphezulu weeglasi iilensi ziya kubonakalisa. Kwezinye iimeko ezithile, izibonakaliso eziveliswa ngamalensi ethu zinokuchaphazela kungekuphela nje umntu onxibayo kodwa nomntu ojonga umntu onxibileyo, kwaye ngamaxesha anzima, le nto inokukhokelela kwiziganeko ezinkulu zokhuseleko. Ngoko ke, ukwenzela ukuba ugweme umonakalo obangelwa yile nto, iifilimu ezichasene ne-reflection ziye zaphuhliswa.
Iingubo ezichasene ne-reflection zisekelwe ekutshintsheni kunye nokuphazamiseka kokukhanya. Ukuyibeka ngokulula, ifilimu echasene ne-reflection igqunywe kumphezulu we-lens ye-spectacle, ukuze ukukhanya okubonakalisiweyo okuveliswe kwindawo yangaphambili nasemva kwefilimu kuphazamise omnye nomnye, ngaloo ndlela kucime ukukhanya okubonakalisiweyo kunye nokuphumeza umphumo wefilimu. anti-reflection.
Ifilimu echasayo
Emva kokuba umphezulu we-lens uqatywe nge-anti-reflection coating, kulula ngakumbi ukushiya amabala. Oku kuya kunciphisa kakhulu "i-anti-reflection amandla" kunye nokukwazi ukubonwa kwelensi. Isizathu salokhu kukuba i-anti-reflection i-coating layer inesakhiwo se-microporous, ngoko ke uthuli olucokisekileyo kunye namabala e-oyile ashiyeka lula kwi-lens surface. Isisombululo sale nto kukugqoka ifilimu ephezulu phezulu kwifilimu echasene ne-reflection, kwaye ukuze unganciphisi amandla efilimu echasene ne-reflection, i-anti-fouling thick of this layer kufuneka ibe yincinci kakhulu.
I-lens efanelekileyo kufuneka ibe nefilimu edibeneyo eyenziwe ngala manqwanqwa amathathu, kwaye ukuze kuphuculwe isakhono sokuchasa ukubonakalisa, kufuneka kubekho iileya ezininzi zeefilimu ezichasene ne-reflection ezibekwe phezulu. Ngokuqhelekileyo, ubukhulu bomaleko ongaguqukiyo yi-3 ~ 5um, ifilimu ye-anti-reflection eninzi malunga ne-0.3 ~ 0.5um, kunye nefilimu ye-thinnest antifouling yi-0.005um ~ 0.01um. Umyalelo wefilimu osuka ngaphakathi ukuya ngaphandle unxibe isambatho esinganyangekiyo, i-multi-layer anti-reflection coating kunye nefilimu echasene ne-fouling.
