Isizukulwane esidala sodokotela bamehlo sasivame ukubuza ukuthi banazo yini izibuko noma amalensi ekristalu, futhi sahleka usulu amalensi e-resin esiwagqoka ngokuvamile namuhla. Ngoba lapho beqala ukuxhumana namalensi e-resin, ubuchwepheshe bokumboza amalensi e-resin abuzange buthuthukiswe ngokwanele, futhi kwakukhona izinkinga ezifana nokungagugi futhi kulula ukushiya amabala. Ngaphezu kwalokho, abakhiqizi abaningi nabathengisi banenqwaba yamalensi engilazi okudingeka athengiswe, ngakho-ke ukushiyeka kwamalensi e-resin kuye kwaqiswa isikhathi esithile.
Amalensi engilazi anezinzuzo zokumelana nokuguguleka kanye nenkomba ephezulu yokukhanya. Kodwa isisindo sawo kanye nobuthakathaka bawo kwabangela ukuthi athathelwe indawo amalensi e-resin. Ngokuthuthuka kwesayensi nobuchwepheshe, ubuchwepheshe bokumboza obuthuthukiswe yimboni yokukhiqiza amalensi e-spectacle buxazulule izinkinga eziningi ekuqaleni kokusungulwa kwamalensi e-resin. Lesi sihloko sizokunikeza isingeniso esifushane sokumboza amalensi e-spectacle, ukuze ukwazi ukuqonda kahle ukumboza kwamalensi owagqokayo kanye nomlando wawo wokuthuthuka.
Ngokuvamile sinezinhlobo ezintathu zokumbozwa kumalensi, okungukuthi, ukumbozwa okumelana nokuguguleka, ukumbozwa okuvimbela ukubonakaliswa, kanye nokumbozwa okuvimbela ukungcola. Izendlalelo ezahlukene zokumbozwa zisebenzisa izimiso ezahlukene. Ngokuvamile siyazi ukuthi umbala wangemuva wamalensi e-resin namalensi engilazi awunambala, futhi imibala engabonakali kumalensi ethu ajwayelekile ibangelwa yilezi zendlalelo.
Ifilimu engagugi
Uma kuqhathaniswa namalensi engilazi (ingxenye eyinhloko yengilazi yi-silicon dioxide, okuyizinto ezingaphili), ubuso bamalensi ezibuko ezenziwe ngezinto eziphilayo kulula ukubugqoka. Kunezinhlobo ezimbili zokuklwebheka ebusweni bamalensi ezibuko ezingabonwa ngokubuka nge-microscope. Enye yenziwe ngesihlabathi esincane kanye nohlalwane. Nakuba ukuklwebheka kungajulile futhi kuncane, umuntu ogqokile akathinteki kalula, kodwa lapho ukuklwebheka okunjalo kuqongelela ngezinga elithile, isimo sokusabalala kokukhanya okubangelwa ukuklwebheka sizothinta kakhulu umbono womuntu ogqokile. Kukhona futhi ukuklwebheka okukhulu okubangelwa uhlalwane olukhulu noma ezinye izinto eziqinile. Lolu hlobo lokuklwebheka lujulile futhi umngcele ulukhuni. Uma ukuklwebheka kuphakathi nelensi, kuzothinta umbono womuntu ogqokile. Ngakho-ke, kwavela ifilimu engagugi.
Ifilimu engagugi nayo idlule ezizukulwaneni eziningana zentuthuko. Ekuqaleni, yaqala ngawo-1970. Ngaleso sikhathi, kwakukholelwa ukuthi ingilazi yayingagugi ngenxa yobulukhuni bayo obuphezulu, ngakho-ke ukuze ilensi ye-resin ibe nokumelana okufanayo kokugugi, kwasetshenziswa indlela yokumboza nge-vacuum. , ungqimba lwezinto ze-quartz lufakwe phezu kwelensi yemvelo. Kodwa-ke, ngenxa yama-coefficients ahlukene okwandisa ukushisa kwezinto ezimbili, ukumboza kulula ukuwa futhi kuyaphuka, futhi umphumela wokumelana nokugugi awumuhle. Isizukulwane esisha sobuchwepheshe sizovela njalo eminyakeni eyishumi esikhathini esizayo, futhi ukumboza kwamanje okungagugi kuyisendlalelo sefilimu exubile se-matrix yemvelo kanye nezinhlayiya ezingaphili. Eyokuqala ithuthukisa ukuqina kwefilimu engagugi, kanti eyesibili ikhulisa ubulukhuni. Inhlanganisela efanelekile yalezi zinto ezimbili ifinyelela umphumela omuhle wokungagugi.
Ukugqoka okulwa nokukhanya
Amalensi esiwagqokayo afana nezibuko ezisicaba, futhi isigameko sokukhanya ebusweni bamalensi ezibuko sizophinde sibonakale. Kwezinye izimo ezithile, ukubonakaliswa okukhiqizwa amalensi ethu kungathinta hhayi kuphela umuntu ogqokile kodwa nomuntu obuka umuntu ogqokile, futhi ngezikhathi ezibucayi, lesi simo singaholela ezigamekweni ezinkulu zokuphepha. Ngakho-ke, ukuze kugwenywe umonakalo obangelwa yilesi simo, kuye kwasungulwa amafilimu alwa nokubonakaliswa.
Izembozo ezivimbela ukubonakaliswa zisekelwe ekushintsheni nasekuphazamisekeni kokukhanya. Kalula nje, ifilimu evimbela ukubonakaliswa imbozwe ebusweni belensi yezibuko, ukuze ukukhanya okubonakalayo okukhiqizwe ebusweni bangaphambili nangemuva befilimu kuphazamise omunye nomunye, ngaleyo ndlela kususe ukukhanya okubonakalayo futhi kufeze umphumela wokuphikisa ukubonakaliswa.
Ifilimu yokulwa nokungcola
Ngemva kokuba ubuso belensi bumbozwe ngengubo evimbela ukubonakaliswa, kulula kakhulu ukushiya amabala. Lokhu kuzonciphisa kakhulu "ikhono lokulwa nokubonakaliswa" kanye nekhono lokubona lelensi. Isizathu salokhu ukuthi ungqimba lwengubo evimbela ukubonakaliswa lunesakhiwo esinama-microporous, ngakho-ke amanye amabala othuli oluncane namafutha ashiywa kalula ebusweni belensi. Isixazululo salesi simo ukumboza ifilimu ephezulu phezulu kwefilimu evimbela ukubonakaliswa, futhi ukuze kunganciphisi ikhono lefilimu evimbela ukubonakaliswa, ubukhulu bokulwa nokungcola kwale ngqimba kudingeka bube buncane kakhulu.
Ilensi enhle kufanele ibe nefilimu ehlanganisiwe eyakhiwe yilezi zingqimba ezintathu, futhi ukuze kuthuthukiswe ikhono lokulwa nokukhanya, kufanele kube nezingqimba eziningi zamafilimu okulwa nokukhanya abekwe ngaphezulu. Ngokuvamile, ubukhulu besendlalelo esingagugiyo bungu-3 ~ 5um, ifilimu engagugiyo enezingqimba eziningi cishe ingu-0.3 ~ 0.5um, kanti ifilimu encane kakhulu engagugiyo ingu-0.005um ~ 0.01um. Ukuhleleka kwefilimu kusukela ngaphakathi kuya ngaphandle yingubo engagugiyo, ingubo engagugiyo enezingqimba eziningi kanye nefilimu engagugiyo.
