Iiglasi zokukhwela ezitshintsha umbala ziiglasi ezikwazi ukulungelelanisa umbala ngexesha ngokuhambelana nokukhanya kwe-ultraviolet yangaphandle kunye nobushushu, kwaye inokukhusela amehlo ekukhanyeni okunamandla, okufanelekileyo kakhulu ukunxiba xa ukhwela.Umgaqo wokutshintsha umbala kukusebenzisa i-lens equlethe i-silver halide microcrystals kunye ne-ultraviolet light reaction emva kokwahlula, ii-athomu zesilivere zifunxa ukukhanya, zinciphisa izinga lokuhanjiswa kwe-lens, ngaloo ndlela utshintsha umbala;Xa ukukhanya okusebenzayo kulahlekile, iiathom zesilivere ziphinda zihlangane kunye neeathom ze-halogen, zibuyela kumbala wazo wokuqala.Iiglasi zokukhwela ezitshintsha umbala aziyongozi kangako emehlweni, kodwa ukukhwela ixesha elide kunokubangela ukudinwa okubonakalayo.Makhe sijonge umgaqo weeglasi zokukhwela ezitshintsha umbala.
Uthini umgaqo weeglasi zokukhwela ezitshintsha umbala?
Iiglasi eziguqula umbala zinokutshintsha umbala weelensi ngokokuqina kokukhanya kwangaphandle, ukuze kukhuseleke amehlo ekuvuseleleni ukukhanya okuqinileyo, abantu abaninzi baya kukhetha ukunxiba iiglasi ezitshintsha umbala xa bekhwele, kodwa uninzi lwabo luyakwenza oko. engayazi umgaqo wokutshintsha umbala, enyanisweni, umgaqo osebenzayo weeglasi zokutshintsha umbala ulula kakhulu.
1. Iiglasi ezikhwelayo ezitshintsha umbala zenziwe ngokongeza izinto ezinombala okhanyayo kwi-lens izinto eziluhlaza ukwenza iilensi ziqulethe i-silver halide (i-silver chloride, i-australide yesilivere) i-microcrystals.Xa ukukhanya okubonakalayo kwe-ultraviolet okanye i-short-wave kufunyenwe, i-halogen ions ikhupha ii-electron, ezithi zithathwe yi-ion zesilivere kwaye ziphendule: i-halide yesilivere engenambala ibolile ibe yi-athomu yesilivere e-opaque kunye ne-athomu ye-halogen ecacileyo.Iiathom zesilivere zifunxa ukukhanya, okunciphisa ukuhanjiswa kwe-lens, ukuze umbala weeglasi utshintshe.
2. Ngenxa yokuba i-halogen kwi-lens enemibala ayiyi kulahleka, ngoko ke ukusabela okubuyiselwe umva kunokwenzeka, emva kokuba ukukhanya okusebenzayo kunyamalale, isilivere kunye ne-halogen iphinda idibanise, ukuze i-lens ibuyele kwimeko ye-original transparent colorless or light-colored state.Ukukhwela rhoqo ngaphandle, isidingo sokumelana nokuvuselela kwelanga, ngoko ukugqoka iiglasi zokukhwela ezinokutshintsha umbala kungcono.Nangona kunjalo, abanye abantu banexhala lokuba iiglasi zokukhwela ezitshintsha umbala ziya kuba yingozi emehlweni.Emva koko, ngaba iiglasi zokukhwela ezitshintsha umbala ziyakwenzakalisa amehlo?
Ngaba iiglasi zokukhwela ezitshintsha umbala ziyingozi emehlweni?
Ukuhanjiswa kokukhanya kweeglasi ezikhwelayo ezitshintsha umbala kusezantsi noko, nangona zinokufunxa uninzi lwe-ultraviolet, i-infrared kunye nemitha eyingozi eyahlukeneyo, kodwa ngenxa yokwakheka kweekhemikhali zesilivere zehalide eziqulethwe kwilensi, ukuhanjiswa kokukhanya kwelensi kumbi kakhulu. , ukusetyenziswa kwexesha elide kunokukhokelela ekukhathaleni okubonakalayo, okungafanelekanga ukugqoka kunye nokusetyenziswa kwexesha elide lokukhwela.Nangona kunjalo, ngenkqubela phambili yobugcisa bokuvelisa, izinga lokuguquka kwemibala kunye nesantya sokuncipha kweelensi ezitshintsha umbala ziphuculwe kakhulu, kwaye iiglasi zokukhwela ezikumgangatho ophezulu eziguqula umbala ziphantse zingabi yingozi.Ukongeza, kufuneka kuqatshelwe ukuba kukho iiglasi zokukhwela ezitshintsha umbala ezisezantsi ezinokutshintsha kombala ongalinganiyo, nokuba kukutshintsha kombala ocothayo ngokufiphala kombala okhawulezayo, okanye utshintsho olukhawulezayo lombala ngombala ocothayo kakhulu, kwaye abanye abawutshintshi umbala, oku. iiglasi ezikhwelayo zinxiba ixesha elide azikwazi ukwenza ukhuseleko lwamehlo olusebenzayo.
