Isizukulwana esidala seengcali zamehlo sasisoloko sibuza ukuba banazo na iilensi zeglasi okanye zekristale, kwaye sahlekisa ngeelensi zeresin esizinxibayo namhlanje. Kuba xa babeqala ukudibana neelensi zeresin, iteknoloji yokugquma iilensi zeresin yayingaphuhliswanga ngokwaneleyo, kwaye kwakukho iingxaki ezifana nokungagugi kwaye kulula ukushiya amabala. Ukongeza, abavelisi abaninzi kunye nabathengisi banenqwaba yeelensi zeglasi ekufuneka zithengiswe, ngoko ke ukusilela kweelensi zeresin kuye kwagqithiswa kangangexesha elithile.
Iilensi zeglasi zinezibonelelo zokungagugi kunye ne-refractive index ephezulu. Kodwa ubunzima bayo kunye nobuthathaka bayo kwenze ukuba ithathelwe indawo ziilensi ze-resin. Ngokuhambela phambili kwesayensi netekhnoloji, itekhnoloji yokugquma eyenziwe lishishini lokuvelisa iilensi ze-spectacle isombulule iingxaki ezininzi ekuqaleni kokuyilwa kweelensi ze-resin. Eli nqaku liza kukunika intshayelelo emfutshane yokugquma iilensi ze-spectacle, ukuze ukwazi ukuqonda ngokungqalileyo ukugquma kweelensi ozinxibayo kunye nembali yophuhliso lwazo.
Ngokwesiqhelo sineentlobo ezintathu zeengubo ezikwiilensi, ezizezi, iingubo ezinganyangekiyo, iingubo ezichasene nokukhanya, kunye neengubo ezichasene nokungcola. Iingubo ezahlukeneyo zengubo zisebenzisa imigaqo eyahlukeneyo. Ngokubanzi siyazi ukuba umbala ongasemva weelensi ze-resin kunye neelensi zeglasi awunambala, kwaye imibala engabonakaliyo kwiilensi zethu ngokubanzi ibangelwa zezi ngubo.
Ifilimu engagugiyo
Xa kuthelekiswa neelensi zeglasi (into ephambili yeglasi yi-silicon dioxide, eyinto engaphiliyo), umphezulu weelensi zemiboniso ezenziwe ngezinto eziphilayo kulula ukuwunxiba. Kukho iintlobo ezimbini zemikrwelo kumphezulu weelensi zemiboniso ezinokubonwa ngokujonga nge-microscope. Omnye wenziwe ngesanti encinci kunye negrabile. Nangona imikrwelo incinci kwaye incinci, umntu onxibe ayichaphazeleki lula, kodwa xa imikrwelo enjalo iqokelelana ukuya kwinqanaba elithile, into yokusasazeka kokukhanya okubangelwa yimikrwelo iya kuchaphazela kakhulu umbono womntu onxibe. Kukwakho nomkrwelo omkhulu obangelwa yigrabile enkulu okanye ezinye izinto eziqinileyo. Olu hlobo lomkrwelo lunzulu kwaye umngcelele urhabaxa. Ukuba umkrwelo uphakathi kwelensi, uya kuchaphazela umbono womntu onxibe. Ke ngoko, ifilimu engagugiyo yavela.
Ifilimu engagugiyo nayo iye yaphuhliswa kwizizukulwana ezininzi. Ekuqaleni, yaqala ngeminyaka yoo-1970. Ngelo xesha, kwakukholelwa ukuba iglasi yayingagugiyo ngenxa yobunzima bayo obuphezulu, ngoko ke ukuze ilensi ye-resin ibe nokumelana okufanayo kokugugiyo, kwasetyenziswa indlela yokugquma nge-vacuum. , umaleko wezinto ze-quartz ugqunywe phezu kwelensi yendalo. Nangona kunjalo, ngenxa yee-coefficients ezahlukeneyo zokwandiswa kobushushu bezinto ezimbini, ukugquma kulula ukuwa kwaye kuyaqhekeka, kwaye isiphumo sokuxhathisa ukugugika asilunganga. Isizukulwana esitsha setekhnoloji siya kuvela rhoqo emva kweminyaka elishumi kwixesha elizayo, kwaye ukugquma kwangoku okungagugiyo lulwaleko lwefilimu exutyiweyo ye-organic matrix kunye namasuntswana angaphiliyo. Owokuqala uphucula ukuqina kwefilimu engagugiyo, kwaye owokugqibela unyusa ubunzima. Ukudibana okufanelekileyo kwezi zimbini kufezekisa isiphumo esihle sokuxhathisa ukugugi.
Ukwambatha okuchasene nokubonakalisa
Iilensi esizinxibayo zifana nezipili ezisicaba, kwaye ukukhanya okubonakalayo kumphezulu weelensi zeglasi kuya kubonakala. Kwezinye iimeko ezithile, ukukhanya okuveliswa ziilensi zethu kunokuchaphazela kungekuphela nje umntu onxibe kodwa nomntu ojonga umntu onxibe, kwaye ngamaxesha anzima, le meko inokukhokelela kwiziganeko ezinkulu zokhuseleko. Ke ngoko, ukuze kuthintelwe umonakalo obangelwa yile meko, kuye kwaveliswa iifilimu ezichasene nokukhanya.
Iingubo ezichasene nokukhanya zisekelwe ekutshintsheni nasekuphazamisekeni kokukhanya. Ngamafutshane, ifilimu echasene nokukhanya igqunywe phezu komphezulu welensi yemiboniso, ukuze ukukhanya okubonakalayo okuveliswe kumphezulu ongaphambili nongasemva wefilimu kuphazamisane, ngaloo ndlela kuthintela ukukhanya okubonakalayo kwaye kufezekise isiphumo sokuchasene nokukhanya.
Ifilimu echasene nokungcolisa
Emva kokuba umphezulu welensi ugqunywe ngengubo ethintela ukukhanya, kulula kakhulu ukushiya amabala. Oku kuya kunciphisa kakhulu "amandla okulwa nokukhanya" kunye nokukwazi ukubona kwelensi. Isizathu soku kukuba umaleko wengubo ethintela ukukhanya unesakhiwo esincinci, ngoko ke uthuli oluncinci kunye namabala eoyile ashiyeka lula kumphezulu welensi. Isisombululo sale meko kukugquma ifilimu ephezulu phezulu kwefilimu ethintela ukukhanya, kwaye ukuze kunganciphisi amandla efilimu ethintela ukukhanya, ubukhulu bokungcolisa obumaleko kufuneka bube buncinci kakhulu.
Ilensi elungileyo kufuneka ibe nefilimu edityanisiweyo eyenziwe zezi layere zithathu, kwaye ukuze kuphuculwe amandla okulwa nokukhanya, kufuneka kubekho iileya ezininzi zeefilimu ezilwa nokukhanya ezibekwe ngaphezulu. Ngokubanzi, ubukhulu beleya enganyangekiyo yi-3 ~ 5um, ifilimu elwa nokukhanya yi-0.3 ~ 0.5um, kwaye ifilimu enciphileyo elwa nokukhanya yi-0.005um ~ 0.01um. Ulandelelwano lwefilimu ukusuka ngaphakathi ukuya ngaphandle yingubo enganyangekiyo, ingubo elwa nokukhanya yi-multi-layer kunye nefilimu elwa nokukhanya.
