1.71 Icyerekezo kimwe HMC Lens optique

Ibisobanuro bigufi:

Lens 1.71 igihe, kora lens nziza cyane kandi yaka, ntabwo byoroshye gukwirakwiza ingano yumukororombya. Byagaragaye ko kongeramo cyclic sulfide resin mubikoresho bya lens bishobora kunonosora igipimo cyangirika cyinzira, ariko resin nyinshi ya cyclic sulfide izagabanya kugabanuka kwumucyo no guturika ibintu. Mugucunga neza ibikubiye muri resin sulfure muri 1.71KR, lens 1.71 igera kumurongo mwinshi wogusenya hamwe numubare wa abbe mugihe itanga urumuri rwiza, ikwirakwizwa rito hamwe nicyerekezo gisobanutse.

Indangantego ya lens yerekeza ku cyerekezo cyo kugabanuka (ubundi bizwi ko ari indangagaciro yo kwanga) ibikoresho bya lens kumyenda y'amaso. Numubare ugereranije wo gupima usobanura uburyo ibikoresho bigenda neza. Kugabanuka k'umucyo bizaterwa nuburyo umucyo wihuse unyura mumurongo.

Ibikoresho bya Lens byashyizwe ku rutonde rwabyo. Iyerekana ryerekana ni igipimo cyumuvuduko wurumuri iyo rinyuze mu kirere kugera ku muvuduko w’urumuri iyo runyuze mu bikoresho bya lens. Nibyerekana urumuri rugoramye uko rugenda runyura. Umucyo uravunika, cyangwa wunamye, hejuru yimbere yinzira, hanyuma nanone uko usohokera. Ibikoresho byunvikana bigabanya urumuri rwinshi, ntabwo rero ibikoresho byinshi bikenewe kugirango ugere ku ngaruka imwe yo kwangirika nkibikoresho bito. Niyo mpamvu lens ishobora gukorwa neza, kandi ikanoroha.

Intangiriro

Hamwe nindorerwamo zamaso zisanzwe, hagati yikirahure cyoroshye kandi impande zinyuma ni ndende kugirango byorohereze gucika aribyo bituma ibirahuri byandikirwa bikora! Indanganturo ndende ifite indangagaciro yo kugabanuka kuruta lens zisanzwe, bivuze ko zidakeneye kuba umubyimba uzengurutse impande zose.

Indanganturo ndende yerekana ko lens ubwayo ishobora kuba yoroshye kandi yoroshye. Ibi bituma ibirahuri byawe bigezweho kandi byoroshye bishoboka. Indangantego-ndende ifite akamaro kanini niba ufite indorerwamo ikomeye yindorerwamo yo kureba kure, kureba kure, cyangwa astigmatism. Nubwo bimeze bityo, nabafite amadarubindi make yandikirwa barashobora kungukirwa ninteguza ndende.

1.71 nigicuruzwa cyo kurwanya. Muri rusange, urwego rwo hejuru rwerekana ibimenyetso, niko umubare wa Abbe ugabanuka. Umubare 1.67 Abbe ni 32, 1.74 ni 33, naho 1.71 irashobora gukora 37. Igitero cyagenze neza. Umubare wa Abbe ni mwinshi, gutatanya ni muke, birasobanutse neza.1.67 bihendutse cyane kurenza 1.74, ariko birabyimbye cyane muburebure. 1.74 mubyukuri biroroshye, ariko igiciro kiri hejuru, intera yo hagati ni nini. Inshuti nyinshi zishobora guhitamo 1.67 gusa kumufuka. Kandi 1.71 yuzuza icyo cyuho.
