Ibirahuri bigenda bihindura ibirahuri nibirahure bishobora guhindura ibara mugihe ukurikije urumuri ultraviolet yo hanze nubushyuhe, kandi birashobora kurinda amaso urumuri rukomeye, rukwiriye kwambara mugihe ugenda.Ihame ryo guhindura amabara ni binyuze mumurongo urimo microcrystal ya silver halide na ultraviolet yumucyo nyuma yo gutandukana, atome ya feza ikurura urumuri, igabanya umuvuduko wogukwirakwiza, bityo igahindura ibara;Iyo urumuri rwo gukora rwatakaye, atome ya feza yongeye guhura na atome ya halogene, igasubira mwibara ryumwimerere.Ibirahuri byiza byo guhindura ibirahure ntabwo byangiza amaso, ariko kugenda igihe kirekire nabyo bishobora gutera umunaniro ugaragara.Reka turebe ihame ryamabara ahindura ibirahuri.
Ni irihe hame ryo guhindura ibirahuri bigenda?
Ibirahuri bihindura amabara birashobora guhindura ibara ryinzira ukurikije ubukana bwurumuri rwo hanze, kugirango urinde amaso kutagira urumuri rukomeye, kuburyo abantu benshi bazahitamo kwambara ibirahuri bihindura amabara mugihe bagenda, ariko benshi muribo ntuzi ihame ryo guhindura amabara, mubyukuri, ihame ryakazi ryibirahure bihindura amabara biroroshye cyane.
1. Ibirahure bigenda bihindura amabara bikozwe mugushyiramo ibikoresho byamabara yumucyo mubikoresho fatizo kugirango lens ikore ifeza halide (silver chloride, silver australide) microcristal.Iyo ultraviolet cyangwa urumuri rugufi rugaragara rwakiriwe, ion ya halogene irekura electron, ifatwa na ion ya feza hanyuma ikabyitwaramo: igice cya feza kitagira ibara kibora muri atome ya feza itagaragara na atome ya halogene.Atome ya feza ikurura urumuri, rugabanya ihererekanyabubasha, kugirango ibara ryibirahure rihinduke.
2. Kuberako halogene iri mumurongo wamabara itazabura, bityo reaction ishobora guhinduka, nyuma yumucyo wo gukora wabuze, ifeza na halogen recombine, kugirango lens igaruke muburyo bwambere butagaragara butagira ibara cyangwa ibara ryumucyo.Kugenda kenshi hanze, gukenera kwihanganira izuba, bityo kwambara ibirahuri bigenda bishobora guhindura ibara nibyiza.Ariko, abantu bamwe bafite impungenge ko ibirahuri bigenda bihindura ibirahure bizangiza amaso.Noneho, ibirahuri bigenda bihindura ibirahure bigenda bikomeretsa amaso?
Ese ibirahuri bigenda bihindura ibirahuri byangiza amaso?
Ihererekanyabubasha ryibirahuri bigenda bihinduranya ibirahuri bigereranywa ni bike, nubwo bishobora gukurura igice kinini cya ultraviolet, infrarafarike hamwe n’urumuri rutandukanye rwangiza, ariko kubera imiterere ya silver halide ya chimique ikubiye muri lens, itumanaho ryoroheje rya lens rirakennye. , gukoresha igihe kirekire birashobora kuganisha ku munaniro ugaragara, ntibikwiriye kwambara igihe kirekire no gukoresha.Ariko, hamwe niterambere ryiterambere ryikoranabuhanga, igipimo cyo guhindura ibara nigipimo cyo kugabanuka kwinzira zihindura amabara byateye imbere cyane, kandi ibirahuri byo mu rwego rwo hejuru bihindura amabara nta kirangirire.Mubyongeyeho, twakagombye kumenya ko hariho ibara ritoya rihindura ibirahuri bigendana nibirahure bitaringaniye, haba amabara atinda guhinduka hamwe nibara ryihuta, cyangwa amabara yihuta cyane hamwe nibara ryihuta cyane, ndetse bamwe ntibahindura ibara, ibi kugendesha ibirahuri kwambara igihe kirekire ntibishobora gukora neza kurinda amaso.
