Iyo ikirere gishyushye, abantu benshi cyane bahitamo kwambara amadarubindi kugirango barinde amaso yabo.Amadarubindi yizuba yizuba agabanijwemo amabara.Yaba abaguzi cyangwa ubucuruzi, amadarubindi y'izuba ntamenyerewe.
Ibisobanuro bya Polarisation
Polarisiyasi, izwi kandi nk'urumuri rukabije, bivuga urumuri rugaragara ari umuraba uhindagurika, hamwe n'icyerekezo cyacyo cyo kunyeganyega cyerekeje ku cyerekezo cyo gukwirakwizwa.Icyerekezo cyinyeganyeza cyumucyo karemano uko bishakiye mu ndege perpendicular yerekeza ku cyerekezo cyo gukwirakwiza;kumucyo ukabije, icyerekezo cyacyo cyo kunyeganyega kigarukira ku cyerekezo runaka mugihe runaka.
Ibyiciro bya polarisiyasi
Polarisiyasi irashobora kugabanywamo ubwoko butatu: umurongo uhindagurika, polarisiyasi ya elliptique, hamwe nizunguruka.Mubisanzwe, ibyo bita polarisiyasi bivuga umurongo wa polarisiyonike, bizwi kandi ko indege ihindagurika.Kunyeganyega k'ubu bwoko bw'urumuri rwashyizwe ku cyerekezo runaka kandi ntigihinduka.Inzira yo gukwirakwira mu kirere ikurikira umurongo wa sinusoidal, kandi projection yayo mu ndege perpendicular yerekeza ku cyerekezo cyo gukwirakwizwa ni umurongo ugororotse.
Indege ikozwe nicyerekezo cyinyeganyeza cyumucyo ucanye umurongo hamwe nicyerekezo cyo gukwirakwizwa byitwa indege yinyeganyeza, naho indege itumbereye yerekeza kunyeganyega kandi ikubiyemo icyerekezo cyo gukwirakwiza yitwa indege ya polarisiyasi.Gutambutsa urumuri karemano binyuze muri polarizeri birashobora gutanga urumuri ruringaniye.
Imikorere ya Polarisation
Mubuzima bwa buri munsi, hari amasoko menshi yumucyo atanga urumuri rwangiza, cyane cyane izuba.Imirasire y'izuba isohora ubwoko butatu bw'urumuri: urumuri rugaragara, urumuri rudasanzwe, n'umucyo ultraviolet (UV).Muri ibyo, urumuri ultraviolet rushobora kwangiza cyane uruhu n'amaso.Umucyo ugaragara uri hagati ya nanometero 380 na 780, mugihe urumuri ultraviolet rugabanijwemo UVA, UVB, na UVC, hamwe nuburebure buri hejuru ya 310nm.UVA, UVB, na UVC ni imirase yangiza.Kumara igihe kinini kuri iyi mirase birashobora kwangiza umubiri.UVB igira ingaruka zikomeye ku iyerekwa, kandi ni "imishwarara yumucyo" yijimye uruhu.Byinshi mu mfuruka y'amaso bikurura ubu bwoko bw'urumuri rwa UVB, ni ngombwa rero guhagarika iri soko ry'umucyo.
Ibice byinshigira umurimo wo gukwirakwiza urumuri, rubafasha guhagarika urumuri rwangiza bitagize ingaruka ku ihererekanyabubasha ryurumuri rugaragara, bityo bikarinda amaso.Usibye umurimo wibanze wo kurinda UV, lens zifite polarize zifite kandi anti-glare, kugaragariza umuhanda, hamwe n’imikorere y’amazi y’amazi, bigatuma bikwiranye no gutwara, kuroba, gutembera, no kwambara buri munsi.
Umusaruro wa Lensarike
Mu magambo y'abalayiki,inzitizikuberako utareba kure ufite imiterere isa na sandwich (igizwe nigice cyimbere cyamadarubindi yizuba, igice cyo hagati cya fibre polarize, hamwe nigice cyinyuma cyinzira zireba kure, byose byashyizwe hamwe).Ibikoresho bisanzwe bikoresha lens bifite indangagaciro ya 1.50 (hariho na 1.60, ariko bihenze).Lens irasa cyane kandi iremereye, kandi niba ibyanditswe birengeje 600 °, ubwiza nibyiza byombi bizagira ingaruka cyane.Urutonde rwibiciro bya lensisire yo kureba kure ni nini cyane kandi biterwa nuburyo uruganda rukora rutekanye kandi rwiza.
Lens ya polarize ifasha mukuyungurura urumuri rutatanye (nkingaruka zo guhuma impumyi), ariko hariho itandukaniro rikomeye mubyiza.Lens zifite ubuziranenge bubi zikunda gusibanganya no gucika, kandi benshi ntibujuje ubuziranenge.
Ibikoresho bya Lensarike
Hariho ubwoko bune busanzwe bwainzitiziku isoko: ibirahuri by'ibirahure, ibyuma bisigara, ibyuma bya PC, hamwe na TAC.
Lens Ibirahuri
Nubwo bidashobora kwihanganira kandi bifite imikorere myiza ya optique, uburemere bwabyo nibibazo byumutekano byatumye kugabanuka kwabo buhoro buhoro.
In Resin
Biroroshye gushushanya, kuremereye, no kwihanganira ingaruka, bigatuma biba kimwe mubikoresho byingenzi byizuba ryizuba.Nyamara, lens ya resin ikunda gukata mugihe cyogusiba, kandi irashobora guteza umutekano muke mugihe byatewe ningaruka zikomeye.
Aces TAC lens
TAC ni kimwe mu bikoresho bya molekulari bisobanutse.Lens ya TAC nk'amadarubindi y'izuba ifite ibintu nka acide na alkali irwanya, yoroheje, hamwe nigiciro kinini.Nyamara, lens ya TAC ifite imbaraga zo kurwanya abrasion hamwe nibiranga optique idahwitse.Nubwo igiciro cyabo gito, batereranywe nabenshi mubirango bizwi cyane mumahanga.
Lens PC
Nibyoroshye, bifite imikorere myiza yo gusiga, hamwe no guhangana ningaruka zikomeye, nabyo bigatuma bihenze cyane.
Lens ya PC yatsinze ibibazo bya spherical hamwe nibibazo bya astigmatism biterwa no guhindura imikorere ya TAC gakondo nyuma yo kuyikora.Zifite imbaraga zikomeye zo guhangana ningaruka (inshuro 60 zicyuma cyikirahure, inshuro 20 zicyuma cya TAC, ninshuro 10 zicyuma cya resin) kandi zikoreshwa cyane mubirere no mubisirikare.Muri icyo gihe, lens ya PC iroroshye, kuba 37% byoroshye kuruta ibisanzwe bisanzwe.
Itandukaniro hagatiLensLens
Lens yahinduwe ikoresha gusa umurimo wo kugabanya urumuri, kandi ntishobora gushungura urumuri.Bashobora gusa kugabanya ubukana bwurumuri, urumuri ultraviolet, nibindi, kandi ntibishobora guhagarika burundu imirase yangiza.Muri icyo gihe, kubera urumuri rwagabanutse, bigira ingaruka ku ihererekanyabubasha, bigahungabanya umutekano ku bambara.
