Iilensi ziyaziwa ngabantu abaninzi, kwaye zidlala indima enkulu ekulungiseni i-myopia kwiiglasi. Iilensi zineelensi zokugquma ezahlukeneyo, ezifana nokutyabeka okuluhlaza, ukutyabeka okuluhlaza okwesibhakabhaka, ukutyabeka okuluhlaza okwesibhakabhaka-mfusa, kunye negolide yodidi oluphezulu. Ukunxiba kunye nokukrazula komgangatho wokugquma sesinye sezizathu eziphambili zokutshintsha iiglasi zamehlo, ngoko ke makhe sifunde ngakumbi malunga neelensi zokugquma.
Ukuphuhliswa kwengubo yelensi
Ngaphambi kokufika kweelensi ze-resin, iilensi zeglasi zazisetyenziswa ngokuqhelekileyo. Izinto eziluncedo kwiilensi zeglasi sisalathiso se-refractive ephezulu, ukuhanjiswa kokukhanya okuphezulu, kunye nokuqina okuphezulu, kodwa zikwanazo nezingeloncedo ezinje ngokuthanda ukophuka, ubunzima, kunye nokungakhuselekanga.
Ukulungisa iintsilelo zeelensi zeglasi, imizi-mveliso iye yavelisa izinto ezahlukahlukeneyo zokutshintsha iilensi zeglasi, kodwa akukho nanye ifanelekileyo. Isixhobo ngasinye sineenzuzo kunye nokungonakali, kwaye kunzima ukufezekisa ukulinganisela. Oku kusebenza nakwiilensi ze-resin zangoku (izinto ze-resin).
Kwiilensi ze-resin zangoku, ukugquma yinkqubo efunekayo. Izinto ze-resin nazo zineendidi ezininzi, ezifana ne-MR-7, MR-8, CR-39, PC, NK-55-C, kunye nezinye izinto ezininzi ze-resin, nganye ineempawu ezahlukeneyo. Nokuba yilensi yeglasi okanye ilensi yeresin, ukukhanya okudlula kumphezulu welensi kuya kwenzeka ngeendlela ezahlukeneyo zokubona: imbonakalo, irefraction, ukufunxwa, ukusasazeka kunye nokuhanjiswa.
Ukugquma i-lens ngefilimu echasene ne-reflective
Ngaphambi kokuba ukukhanya kufikelele kwi-interface yomphezulu we-lens, yi-100% yamandla okukhanya, kodwa xa iphuma kwi-lens kwaye ingena esweni, ayisekho i-100% yamandla okukhanya. Okukhona iphezulu ipesenti yamandla okukhanya, kokukhona ingcono ukuhanjiswa kokukhanya, kwaye kokukhona iphezulu umgangatho womfanekiso kunye nesisombululo.
Kwizinto ezithile zelensi, ukunciphisa ukulahleka kokubonakalisa kuyindlela eqhelekileyo yokwandisa ukuhanjiswa kokukhanya. Okukhona kubonakaliswe ngakumbi ukukhanya, kokukhona isezantsi ukuhanjiswa kwelensi, okukhokelela kumgangatho ongemhle wokucinga. Ngoko ke, ukunciphisa ukubonakaliswa kuye kwaba yingxaki ekufuneka i-resin lens isonjululwe, kwaye ifilimu echasene ne-reflective (ifilimu ye-AR) isetyenziswe kwi-lens (ekuqaleni, iingubo ezichasene ne-reflective zisetyenziswe kwezinye iilensi ezibonakalayo).
Ifilimu echasa ukubonakalisa ifilimu isebenzisa umgaqo wongenelelo ukuze ufumane ubudlelwane phakathi kokukhanya kokukhanya kwelensi egqunyiweyo yomaleko wefilimu kunye nobude bokukhanya kwesehlo, ubukhulu bomaleko wefilimu, isalathiso sokukhanyela somaleko wefilimu, kunye isalathiso se-refractive ye-lens substrate, evumela ukukhanya okudlula kwinqanaba lefilimu ukukhansela ngaphandle, ukunciphisa ukulahlekelwa kwamandla okukhanya kwi-lens surface kunye nokuphucula umgangatho wokucinga kunye nesisombululo.
Iingubo ezichasene ne-reflective zihlala zisebenzisa i-oxides zetsimbi ezicocekileyo ezifana ne-titanium dioxide kunye ne-cobalt oxide, ezifakwe kwi-lens surface ngokusebenzisa inkqubo yokuphuma evaporation (i-vacuum deposition) ukufezekisa imiphumo emihle yokuchasana ne-reflective. Iingubo ezichasene ne-anti-reflective zihlala zishiya iintsalela, kwaye ezininzi iileya zefilimu ziphezulu kuluhlu lombala oluhlaza.
Umbala wefilimu ye-anti-reflective unokulawulwa, umzekelo, ukuvelisa ifilimu eluhlaza okwesibhakabhaka, ifilimu ye-blue-violet, ifilimu ye-violet, ifilimu engwevu, njalo njalo. Iingqimba zefilimu ezinemibala eyahlukeneyo zineeyantlukwano kwinkqubo yokuvelisa. Ngokomzekelo, ifilimu eluhlaza okwesibhakabhaka ithetha ukuba umboniso ophantsi kufuneka ulawulwe, kwaye ubunzima bokugquma bukhulu kunoko kwefilimu eluhlaza. Nangona kunjalo, umahluko ekuhanjisweni kokukhanya phakathi kweefilimu eziluhlaza kunye neluhlaza unokuba ngaphantsi kwe-1%.
Kwiimveliso zelensi, iifilimu eziluhlaza okwesibhakabhaka ziqheleke kakhulu phakathi ukuya kwiilensi eziphezulu. Ngokomgaqo, ukuhanjiswa kokukhanya kweefilimu eziluhlaza kuphezulu kunoko kuluhlaza (qaphela ukuba oku kusemthethweni) kuba ukukhanya ngumxube wamaza ohlukeneyo obude, kwaye amaza ahlukeneyo aneendawo ezahlukeneyo zokucinga kwiretina. Phantsi kweemeko eziqhelekileyo, ukukhanya okutyheli-luhlaza kufanekiselwa ngokuchanekileyo kwiretina, kwaye ulwazi olubonakalayo olunikelwa kukukhanya okuluhlaza luphezulu ngokwentelekiso, ngoko iliso lomntu liyakuva ukukhanya okuluhlaza.
Ukugquma i-lens ngefilimu enzima
Ukongeza kwi-transmission yokukhanya, zombini i-resin kunye ne-glass materials ine-drawback ebalulekileyo: iilensi azinzima ngokwaneleyo.
Isisombululo kukusombulula oku ngokongeza ifilimu enzima yokugubungela.
Ukuqina komphezulu weelensi zeglasi kuphezulu kakhulu (ngokukodwa ukushiya imikhondo encinci xa kukrwela izinto eziqhelekileyo), kodwa oku akunjalo kwiilensi zeresin. Iilensi ze-resin zikrwelwa ngokulula ngezinto eziqinileyo, ezibonisa ukuba aziyi kunxitywa.
Ukuphucula ukuxhatshazwa kwe-lens yokugqoka, kuyimfuneko yokongeza ifilimu enzima yokugqoka kwi-lens surface. Iingubo zefilimu enzima zihlala zisebenzisa ii-athomu ze-silicon kunyango olunzima, zisebenzisa isisombululo esinzima esine-organic matrix kunye neengqungquthela ze-ultrafine ezibandakanya izinto ze-silicon. Ifilimu enzima ngaxeshanye inokuqina kunye nokuqina (umaleko wefilimu kumphezulu we-lens unzima, kwaye i-lens substrate ayinabuqhophololo, ngokungafaniyo neglasi eyophuka lula).
Ubuchwephesha obuphambili banamhlanje bokugquma ifilimu enzima kukuntywiliselwa. Ukugquma kwefilimu enzima kunzima, malunga ne-3-5μm. Kwiilensi ze-resin ezineengubo zefilimu ezinzima, ziyakwazi ukuchongwa ngesandi sokucofa kwi-desktop kunye nokukhanya kombala we-lens. Iilensi ezivelisa isandi esicacileyo kwaye zinemiphetho eqaqambileyo ziye zafumana unyango olunzima.
Ukugquma i-lens ngefilimu echasene ne-fouling.
Ifilimu echasene ne-reflective kunye nefilimu enzima zizinto ezimbini ezisisiseko zokugquma iilensi zeresin okwangoku. Ngokuqhelekileyo, ifilimu enzima ifakwe kuqala, ilandelwa yifilimu echasene ne-reflective. Ngenxa yemida yangoku yezixhobo zefilimu ezichasene ne-reflective, kukho ukuchasana phakathi kwezakhono ezichasayo kunye ne-anti-fouling. Ngenxa yokuba ifilimu echasene ne-reflective ikwimeko enemingxuma, ithanda kakhulu ukwenza amabala kumphezulu welensi.
Isisombululo kukongeza uluhlu olongezelelweyo lwefilimu echasene ne-fouling phezulu kwefilimu echasene ne-reflective. Ifilimu echasayo ifakwe ikakhulu ngama-fluorides, angakwazi ukugubungela i-porous anti-reflective layer film, ukunciphisa indawo yokudibanisa phakathi kwamanzi, ioli, kunye ne-lens, ngelixa ingatshintshi ukusebenza kwe-optical ye-anti-reflective film.
Ngokunyuka kokwahluka kweemfuno, kuye kwaphuhliswa iileya zefilimu ezisebenzayo ngakumbi nangakumbi, ezifana nefilimu ye-polarizing, ifilimu echasene ne-static, ifilimu yokukhusela ukukhanya okuluhlaza, ifilimu echasene nenkungu, kunye nezinye iileya zefilimu ezisebenzayo. Izinto ezifanayo zelensi, isalathisi esifanayo se-lens refractive, iimpawu ezahlukeneyo, kwaye nangaphakathi kwe-brand efanayo, kunye nezinto ezifanayo, uluhlu oluhlukeneyo lweelensi lunokwahlukana kwexabiso, kunye neengubo ze-lens zesinye sezizathu. Kukho ukungafani kweteknoloji kunye nomgangatho weengubo.
Kwiintlobo ezininzi zeengubo zefilimu, kunzima kumntu oqhelekileyo ukuqonda umahluko. Nangona kunjalo, kukho uhlobo olulodwa lokugquma apho iziphumo zinokubonwa ngokulula: iilensi zokuthintela ukukhanya okuluhlaza okwesibhakabhaka (iteknoloji edla ngokusetyenziswa kwiilensi zokuthintela ukukhanya okuluhlaza okwesibhakabhaka).
Isibane esibhlowu esivalileyo esivala ilensi sihluza ukukhanya okuluhlaza okuyingozi kuluhlu lwe-380-460nm ngaphaya komgangatho wefilimu oblowu. Nangona kunjalo, kukho iyantlukwano ekusebenzeni kwangempela phakathi kweemveliso ezivela kubavelisi abahlukeneyo. Iimveliso ezahlukeneyo zibonisa umahluko ekusebenzeni kokukhanya okuluhlaza okwesibhakabhaka, umbala osisiseko, kunye nokuhanjiswa kokukhanya, okukhokelela ngokwendalo kumaxabiso ahlukeneyo.
Ukhuseleko lokugquma iilensi
Iilensi zokugquma zinovelwano kumaqondo obushushu aphezulu. Iingubo kwiilensi ze-resin zisetyenziswe kamva kwaye bonke babelana ngobuthathaka obuqhelekileyo: banomdla kumaqondo okushisa aphezulu. Ukukhusela iilensi zokugquma ekugqabhukeni kunokwandisa ngokufanelekileyo ubomi beelensi. Ezi meko zilandelayo zilandelayo ziqhele ukwenza umonakalo kwiilensi zokugquma:
1.Ukubeka iindondo kwideshibhodi yemoto emini emaqanda ehlotyeni.
2.Ukunxiba iiglasi okanye ukuzibeka kufutshane ngelixa usebenzisa i-sauna, ukuhlamba, okanye ukuntywila kumthombo oshushu.
3.Ukupheka ekhitshini kumaqondo aphezulu e-oyile; ukuba ioli eshushu igalela kwiilensi, zinokugqabhuka ngoko nangoko.
4.Xa usitya imbiza eshushu, ukuba isuphu eshushu itshiza kwiilensi, zinokugqabhuka.
5.Ukushiya iiglasi kufuphi nezixhobo zendlu ezivelisa ukushisa ixesha elide, njengezibane zedesksi, iithelevishini, njl.
Ukongeza kula manqaku angentla, kukwabalulekile ukuba uhlale kude nolwelo oluqinileyo lwe-asidi okanye lwealkaline ukuthintela iifreyimu okanye iilensi ukuba zingagqwali.
Ukugqabhuka kweengubo zelensi kunye nemikrwelo yahluke kakhulu. Ukuqhuma kubangelwa ukuvezwa kwamaqondo okushisa aphezulu okanye ulwelo lweekhemikhali, ngelixa ii-scratches zibangelwa ukucocwa okungafanelekanga okanye impembelelo yangaphandle.
Enyanisweni, iiglasi ziyimveliso ebuthathaka. Aziva eziva ephantsi koxinzelelo, ukuwa, ukugoba, ubushushu obuphezulu nolwelo oludlekayo.
Ukukhusela ukusebenza kwe-optical yomaleko wefilimu, kuyimfuneko:
1.Xa ukhulula iiglasi zakho, zibeke kwindawo yokukhusela kwaye uzigcine kwindawo apho abantwana abangenako ukufikelela kuyo.
2.Coca iiglasi nge-detergent engathathi hlangothi ehlanjululweyo usebenzisa amanzi apholileyo. Akukhuthazwa ukusebenzisa naluphi na ulwelo ukucoca iiglasi.
3.Kwimimandla yokushisa okuphezulu (ngokukodwa ngexesha lokuhlamba okanye ukupheka), kuyacetyiswa ukuba ugqoke iiglasi ezindala ukukhusela umonakalo kwiilensi zeeglasi ezintsha.
Abanye abantu banokuhlamba iiglasi zabo ngamanzi afudumeleyo ngelixa behlamba iinwele zabo, ubuso, okanye behlamba ukuze benze iiglasi zicoceke. Nangona kunjalo, oku kunokubangela umonakalo omkhulu kwiilensi zokugquma kwaye kunokwenza iilensi zingasebenzi. Kubalulekile ukugxininisa ukuba iiglasi kufuneka zihlambuluke kuphela nge-detergent engathathi hlangothi ehlanjululweyo esebenzisa amanzi apholileyo!
Ukuququmbela
ngokuqhubela phambili okuqhubekayo kwetekhnoloji yokugquma, iimveliso zamehlo zanamhlanje zenze inkqubela phambili ebonakalayo ekudluliseleni ukukhanya, ukuchasa umkrwelo, kunye neepropathi ezichasene nokungcolisa.
