Igisekuru cyakera cya optique bakunze kubaza niba bafite ibirahuri cyangwa kirisiti ya kirisiti, bagasebya lens resin dusanzwe twambara muri iki gihe.Kuberako igihe babonanaga bwa mbere na resin lens, tekinoroji yo gutwika ibyuma bya resin ntabwo yateye imbere bihagije, kandi hariho ibibi nko kutirinda kwambara kandi byoroshye gusiga irangi.Byongeye kandi, abayikora n'abacuruzi benshi bafite ibirahuri by'ibirahure bigomba kugurishwa, bityo amakosa ya resin lens akabya gukabya mugihe runaka.
Ibirahuri by'ibirahure bifite ibyiza byo kwihanganira kwambara no kwerekana ibintu byinshi.Ariko uburemere bwacyo no gucika intege byatumye isimburwa na resin lens.Iterambere rya siyansi n’ikoranabuhanga, tekinoroji yo gutwikira yatejwe imbere n’inganda zikora indorerwamo za lens yakemuye ibibazo byinshi mu ntangiriro yo kuvumbura lens.Iyi ngingo izaguha intangiriro ngufi yo gutwikira indorerwamo, kugirango urusheho gusobanukirwa neza ibifuniko bya lens wambara namateka yiterambere ryabo.
Mubusanzwe dufite ubwoko butatu bwo gutwikira kuri lens, aribyo, gutwikira kwangirika, kwifata,Ibice bitandukanye byo gutwikira bikoresha amahame atandukanye.Mubisanzwe tuzi ko ibara ryinyuma ryibibabi byombi hamwe nibirahuri bitagira ibara, kandi amabara yoroheje kumurongo rusange azanwa nizi nzego.
Kwambara firime
Ugereranije n'ibirahuri by'ibirahure (igice cy'ingenzi cy'ikirahure ni dioxyde ya silicon, ikaba ari ibintu bidakoreshwa), ubuso bw'indorerwamo z'indorerwamo zikoze mu bikoresho kama biroroshye kwambara.Hariho ubwoko bubiri bwo gushushanya hejuru yinteguza zishobora kugaragara hifashishijwe microscope.Imwe ikozwe mu mucanga muto na kaburimbo.Nubwo gushushanya ari bito kandi bito, uwambaye ntabwo agira ingaruka ku buryo bworoshye, ariko iyo ibishushanyo nk'ibyo byegeranije ku rugero runaka, ibintu byo gukwirakwiza urumuri byatewe no gushushanya bizagira ingaruka cyane ku iyerekwa ry'uwambaye.Hariho kandi igishushanyo kinini cyatewe na kaburimbo nini cyangwa ibindi bintu bikomeye.Ubu bwoko bwo gushushanya bwimbitse kandi impande zose zirakomeye.Niba igishushanyo kiri hagati yinzira, bizagira ingaruka kumyerekano.Kubwibyo, firime idashobora kwambara.
Filime idashobora kwambara nayo yagiye mu bihe byinshi byiterambere.Ubwa mbere, yatangiye mu myaka ya za 70.Muri kiriya gihe, abantu bemezaga ko ikirahuri kitarwanya kwambara kubera ubukana bwacyo bwinshi, bityo kugirango kugirango lens ya resin igire imyambarire imwe, hakoreshejwe uburyo bwo gutwikira vacuum., urwego rwibikoresho bya quartz rushyizwe hejuru yinzira ngengabuzima.Ariko, kubera coefficient zitandukanye zo kwagura ubushyuhe bwibikoresho byombi, gutwikira biroroshye kugwa no kuvunika, kandi ingaruka zo kurwanya kwambara ntabwo ari nziza.Igisekuru gishya cyikoranabuhanga kizagaragara buri myaka icumi mugihe kizaza, kandi igipfundikizo kidashobora kwambara ni uruvange rwa firime ivanze na matrike kama na organic organique.Iyambere itezimbere ubukana bwa firime idashobora kwambara, hanyuma iyongera ubukana.Guhuza gushyira mu gaciro byombi bigera ku ngaruka nziza yo kwihanganira kwambara.
Kurwanya-kwigaragaza
Lens twambara ni nkindorerwamo ziringaniye, kandi ibyabaye kumucyo hejuru yikirahure lens nayo izagaragaza.Rimwe na rimwe, ibitekerezo byakozwe ninzira zacu ntibishobora kugira ingaruka kubambaye gusa ahubwo no ku muntu ureba uwambaye, kandi mugihe gikomeye, iki kibazo gishobora guteza umutekano muke.Kubwibyo, kugirango twirinde ibibi byatewe niki kintu, hateguwe firime zo kurwanya ibitekerezo.
Kurwanya-kwigaragaza bishingiye ku guhindagurika no kwivanga k'umucyo.Tubivuze mu buryo bworoshe, firime anti-reflake yashizwe hejuru hejuru yinteguza, kugirango urumuri rwerekanwe rwakozwe hejuru yimbere ninyuma ya firime rwivanga hagati yabo, bityo ruzimya urumuri rugaragara kandi rugera ku ngaruka za Kurwanya.
Filime yo kurwanya nabi
Ubuso bwa lens bumaze gutwikirwa hamwe na anti-reaction, biroroshye cyane gusiga ikizinga.Ibi bizagabanya cyane "ubushobozi bwo kurwanya-kwigaragaza" nubushobozi bwo kureba bwa lens.Impamvu yabyo nuko igipande kirwanya anti-reaction gifite imiterere ya microporome, bityo umukungugu mwiza hamwe namavuta yamavuta bisigara byoroshye kumurongo wa lens.Igisubizo kuri iki kibazo ni ugutwikira firime yo hejuru hejuru ya firime yo kurwanya anti-reaction, kandi kugirango utagabanya ubushobozi bwa firime yo kurwanya anti-reaction, umubyimba wo kurwanya ububi bwuru rwego ugomba kuba muto cyane.
Lens nziza igomba kuba ifite firime igizwe nizi nzego eshatu, kandi kugirango hongerwe imbaraga zo kurwanya-kwigaragaza, hagomba kubaho ibice byinshi bya firime zo kurwanya-hejuru.Muri rusange, ubunini bwurwego rudashobora kwambara ni 3 ~ 5um, firime ya anti-reflake igizwe na 0.3 ~ 0.5um, na firime yoroheje cyane ni 0.005um ~ 0.01um.Itondekanya rya firime kuva imbere kugeza hanze ni impuzu idashobora kwambara, igipande kinini kirwanya anti-reaction hamwe na firime irwanya ububi.
