Mu rwego rwo guhanga udushya, igishushanyo mbonera cyashyizwe mubyiciro bibiri: serefegitura na aspheric.Lens ya asiferique, itwarwa no gukurikirana ubunebwe, ikenera guhinduka mugihe cyo kugurumana, gutandukana cyane uhereye kumurongo gakondo wububiko.Igishushanyo mbonera, cyahoze gisanzwe, cyaranzwe no kwiyongera no kugoreka.Ibi akenshi byaviriyemo ibibazo bigaragara nkibishusho bitagaragara, iyerekwa ryerekanwe, hamwe numwanya muto wo kureba.
Noneho, igishushanyo mbonera cyagaragaye nkimbaraga zo gukosora, gikemura ibyo kugoreka amashusho neza kandi gitanga igisubizo gitanga lens zoroheje kandi zoroshye ariko kandi zirasa neza.Icy'ingenzi, iri terambere ntirishobora guhungabanya imbaraga zidasanzwe zirwanya ingaruka, byerekana uburambe bwo kwambara neza.
Indanganturo ya spherical lens ifite ibibi bigaragara - ibintu byarebaga hafi ya lens bigaragara ko bigoramye, bikagabanya umurima wambaye.Mubihe aho ikoranabuhanga ridahwema gutera imbere, lensike ya aspheric - igitangaza cyiza cya optique - igabanya aberrasi kumurongo wa lens, yagura cyane umurongo wo kureba kugirango uhuze ibyifuzo byabakiriya.Lens ya asiferique iranga umurongo uhamye kandi woroshye, byongera ubwiza nubwiza.Cyane cyane mugihe gifite imbaraga nyinshi zo kugabanya, zigabanya ubuhanga bwo kugoreka amaso, bigatuma bahitamo neza kubaguzi bafite ibyo bakeneye cyane.
Igisobanuro kiranga lensike ya aspheric nuburyo bwihariye bwo kugabanuka.Igishushanyo mbonera gitanga inyungu nyinshi kurenza lensike gakondo:
1.Ubusobanuro: Bikoreshejwe hamwe nuburyo bwihariye bwo gutwikira, lensike ya aspheric itanga imikorere yintangarugero, itanga uburambe bwo kureba neza.
2.Ihumure: Umucyo rero ntushobora kumvikana, lensifike ya aspheric igabanya 'uburemere' mumaso yawe, bigatuma wambara kandi utuje.
3.Icyerekezo gisanzwe: Igishushanyo mbonera cyabo kigabanya kugoreka ibintu, biganisha ku myumvire ifatika kandi yuzuye.
Ugereranije utubumbe twa sherfike na aspheric yibikoresho bisa kandi byandikirwa, lensike ya aspheric igaragara neza, yoroheje, kandi itanga uburambe kandi bwiza bwo kureba.Urebye imiterere ya lens irwanya isoko yumucyo byerekana ko imitekerereze iva mumurongo isanzwe ikomera (usibye mumashanyarazi maremare);lensike ya aspheric, ariko, yerekana ubugari bunini bitewe nuburyo butandukanye butandukanye hejuru yabyo.
Impande za periferique yinzira gakondo ntizigaragara cyane ahubwo zigoreka kandi zigoreka kureba ibintu, ibintu bizwi nka aberration.Kugirango ugere ku gishushanyo cyoroheje, ibikoresho byerekana ibimenyetso byoroheje byakoreshejwe mu gukora lens.Byongeye kandi, iyo urebye ukoresheje lensifike, isura yuwambaye mumaso iragoramye.Ibice bya Asiferique, bitandukanye, bigabanya hagati yubugari no hagati yuburebure, bikavamo lens yoroheje ikuraho aberiferique, bityo bigatanga uburambe busanzwe.
Lens ya Aspheric itanga umurongo mugari kandi udafunze umurongo wo kureba ku nkombe, hamwe na minisiteri ntoya, byerekana amashusho nibisanzwe.Izi lens zirakomeye inshuro eshatu ugereranije na bagenzi babo, bigatuma zikoreshwa cyane kubambara bato.Hamwe na -5.00DS yandikirwa, lensike ya aspheric iroroshye 26% kuruta lensike.Ubuso bwabo bushimishije butuma isi ibona ibintu bisanzwe, bitagabanijwe, haba hafi ndetse no kure, bikagabanya umunaniro wamaso mugihe kirekire.
Nibyiza kubwa mbere bambara amadarubindi, cyane cyane abanyeshuri n'abakozi bo mu biro, lensike ya aspheric igabanya cyane kutoroherwa kwambere bijyanye no kwambara amadarubindi.Nubundi buryo bwiza cyane kubakoresha lens ya contact, bakora nk'imyenda yimbere murugo.Lenseri ya asiferi yigana hafi iyerekwa karemano, bisa nuburambe hamwe ninzira yo guhuza.Nibyiza kubantu bahitamo gupfobya ibyo banditse cyane, bifuza kwirinda kugaragara kwamaso mato hamwe nikirahure cya myopiya, gushaka koroshya uburemere bwinzira zabo, cyangwa bafite ibyo bakeneye bitandukanye kuri buri jisho.
Lenseri ya Aspheric irashobora gutanga indangagaciro ziciriritse zisa nuburyo bworoshye kandi buringaniye nkibipimo byoroheje byerekana indangagaciro, kugabanya impande zombi no kugaburira ahantu hanini harebwa ibyo abakiriya bakeneye.
