1.67 Gukata Ubururu Kuzunguruka Ifoto Yumukara HMC Lens optique Yerekana Ishusho

Ibisobanuro bigufi:

lens nziza, ibikoresho nurufunguzo

Ibikoresho byinzira zifite uruhare runini mugukwirakwiza kwabo, kuramba hamwe numubare wa Abbe (ishusho yumukororombya hejuru yinzira). Irashobora gukora ubushakashatsi bwimbitse niterambere kubikoresho, hamwe nubwiza bugenzurwa nibikorwa byiza.

firime ya firime, kora lens byoroshye kwambara

Lens nziza ya firime irashobora guha lens imikorere myiza cyane, ntabwo imikorere ya optique gusa nka transmitance yatejwe imbere cyane, ubukana bwayo, kwihanganira kwambara, kuramba bizatera imbere cyane.

Kugirango ubone ibintu byiza kandi byumwimerere byiza, ubuso bwa lens bwashizwemo nubunini runaka bwa firime imwe cyangwa ibice byinshi bya optique hakoreshejwe uburyo bwa fiziki na chimique.

Gushimangira firime: byitwa kandi byongeweho firime ya firime, ni igipande cya oxyde yicyuma hamwe na agent ihuza ivanze nindangantego ya lens. Ifite ubukana bwinshi, gufatira hejuru, gukwirakwiza urumuri rwinshi nibindi biranga, birashobora kunoza neza uburyo bwo kwihanganira kwambara kwinzira, ntibyoroshye gukuramo no guhondo, kuzamura ubuzima bwa serivisi bwinzira.

Ibirahuri bifunga ubururu ni ibirahure bibuza urumuri rwubururu kurakaza amaso yawe. Ibirahuri bidasanzwe birwanya ubururu birashobora gutandukanya ultraviolet nimirasire kandi birashobora gushungura urumuri rwubururu, bibereye gukoresha mudasobwa igendanwa cyangwa televiziyo.

Intangiriro

Mugihe uhisemo ibirahuri bihindura ibirahure, imikorere yibiranga lens, gukoresha ibirahuri, ibisabwa kugiti cyawe nibindi bintu bigomba kwitabwaho. Lens ya Photochromic irashobora kandi gukorwa mumabara atandukanye, nk'imvi, umukara nibindi.

Icyatsi kibisi: gukuramo urumuri na 98% ultraviolet. Inyungu nini yibara ryinshi ni uko ibara ryumwimerere ryibibanza ritazahindurwa ninzira, kandi kunyurwa kwinshi nuko bishobora kugabanya neza ubukana bwurumuri. Icyatsi kibisi gishobora gukuramo ibara iryo ari ryo ryose, bityo ibibera bizaba ari umwijima gusa, ariko nta tandukaniro rigaragara ryibara ryerekana, byerekana ibyiyumvo nyabyo nyabyo. Biri mubara ridafite aho ribogamiye, muburyo bwo gukoresha abantu bose.
