Amalensi ashintsha umbala, aziwa nangokuthi "ama-photosensitive lens".Ngenxa yokuthi ikhemikhali ye-halide esiliva yengezwa kwilensi, ilensi yasekuqaleni ebonisa ngale nengenambala izoba nemibala ekhanyayo lapho ichayeke ekukhanyeni okunamandla ukuze ivikeleke, ngakho ifanele ukusetshenziswa kwangaphakathi nangaphandle.
Ilensi ye-chromic yenziwe ngengilazi yokubona equkethe i-silver halide microcrystal.Ngokomgomo we-tautotransformation yombala wokukhanya obuyiseleka emuva, ilensi ingaba mnyama ngokushesha ngaphansi kokukhanya kwelanga nokukhanya kwe-ultraviolet, imunce ngokuphelele ukukhanya kwe-ultraviolet, futhi ibe nokumunca okumaphakathi kokukhanya okubonakalayo.Ukubuyela ebumnyameni, kungabuyisela ngokushesha ukukhanya okungenambala.
I-lens eshintsha umbala isetshenziswa kakhulu endaweni evulekile, iqhwa, indawo yokusebenza yomthombo wokukhanya oqinile wasendlini, ukuvimbela ilanga, ukukhanya kwe-ultraviolet, ukuxhopha kokulimala kweso.
NgesiNgisi esicacile, i-halide esiliva ekukhanyeni okukhanyayo iphenduka izinhlayiya zesiliva ezimnyama.
Indlela yokukhetha
Lapho sikhetha izibuko ezishintsha umbala, sicabangela ikakhulukazi imisebenzi nezici ze-lens, ukusetshenziswa kwezibuko, kanye nezidingo zomuntu siqu zombala.Amalensi e-Photochromic angenziwa futhi abe nemibala ehlukahlukene, njengempunga, ensundu, njll.
1, ilensi empunga:ikwazi ukumunca infrared kanye 98% ultraviolet.Inzuzo enkulu yelensi empunga ukuthi umbala wangempela wendawo ngeke ushintshwe ilensi, futhi ukwaneliseka okukhulu kakhulu ukuthi ingasebenza kahle kakhulu ekwehliseni amandla okukhanya.Ilensi empunga ingakwazi ukumunca ngokulinganayo noma iyiphi i-spectrum yombala, ngakho indawo izoba mnyama kuphela, kodwa ngeke kube khona umehluko obalulekile wombala, obonisa umuzwa wangempela wemvelo.Ingowesistimu yombala engathathi hlangothi, ivumelana naso sonke isixuku okufanele sisetshenziswe.
2. Amalensi aphinki:Lona umbala ovame kakhulu.Imunca u-95% wokukhanya kwe-ultraviolet.Uma isetshenziswa njengezibuko zokulungisa umbono, abesifazane okufanele bazigqoke njalo kufanele bakhethe ilensi ebomvu ekhanyayo, ngoba ilensi ebomvu ekhanyayo idonsa imisebe ye-ultraviolet kangcono futhi inciphisa amandla okukhanya okuphelele, ngakho-ke ogqokile uzozizwa ekhululekile.
3, ilensi ensomi ekhanyayo:kanye nelensi epinki, ngenxa yombala wayo ojulile, othandwa kakhulu ngabesifazane abavuthiwe.
4. Ilensi enombala ontulayo:ingakwazi ukumunca ukukhanya kwe-ultraviolet okungu-100%.Ilensi enombala ontulayo ingahluza inani elikhulu lokukhanya okuluhlaza okwesibhakabhaka, okungathuthukisa ukugqama okubonakalayo nokucaca, ngakho yamukelwe abagqokile.Ikakhulukazi esimweni sokungcoliswa komoya okubi noma umphumela wokugqoka inkungu kungcono.Ngokuvamile, zivimbela ukukhanya okuvela ezindaweni ezibushelelezi nezikhanyayo, futhi umuntu ogqokile usengakwazi ukubona izingxenye ezinhle.Zilungele abashayeli.Ezigulini ezineminyaka ephakathi nendawo nezikhulile ezinombono ophezulu ngaphezu kwama-degree angu-600, kungabekwa kuqala.
5, ilensi eluhlaza okwesibhakabhaka:i-beach beach play ingagqoka i-sun blue lens, eluhlaza okwesibhakabhaka ingahlunga ngokuphumelelayo amanzi kanye nokubonakaliswa kwesibhakabhaka kokukhanya okwesibhakabhaka.Amalensi aluhlaza kufanele agwenywe lapho ushayela, njengoba enza kube nzima ukuhlukanisa umbala wezimpawu zomgwaqo.
6, ilensi eluhlaza:I-lens eluhlaza ingaba nayo kanye nelensi empunga, ingakwazi ukumunca ukukhanya kwe-infrared kanye no-99% wokukhanya kwe-ultraviolet.Ikhulisa ukukhanya okuluhlaza okufinyelela esweni ngenkathi imunca ukukhanya, ukuze ibe nomuzwa opholile futhi onethezekile.Ilungele abantu abanamehlo akhathele.
7, ilensi ephuzi:ingakwazi ukumunca u-100% we-ultraviolet, futhi ingavumela i-infrared kanye no-83% wokukhanya okubonakalayo nge-lens.Isici esiphawuleka kakhulu samalensi aphuzi ukuthi amunca iningi lokukhanya okuluhlaza okwesibhakabhaka.Ngoba lapho ilanga likhanya emkhathini, libonakala ngokuyinhloko njengokukhanya okuluhlaza okwesibhakabhaka (okuchaza ukuthi kungani isibhakabhaka siluhlaza okwesibhakabhaka).Amalensi aphuzi angenza izigcawu zemvelo zicace ngokumunca ukukhanya okuluhlaza okwesibhakabhaka.
Ngalesi sizathu, amalensi aphuzi avame ukusetshenziswa njenge "izihlungi ezikhanyayo" noma abazingeli lapho bezingela.Uma sikhuluma ngokuqinile, lawa ma-lens awawona amalensi elanga ngoba anciphisa kancane ukukhanya okubonakalayo, kodwa abuye abizwe ngokuthi amazibuko okubona ebusuku ngoba athuthukisa ukugqama futhi anikeze izithombe ezinembe kakhudlwana phakathi namahora anenkungu nokuhwalala.Abanye abantu abasha bagqoka i-lens ephuzi "izibuko zelanga" njengomhlobiso, abadlali be-glaucoma futhi badinga ukuthuthukisa ukukhanya okubukwayo kweziguli ezingakhetha.
Ngesidingo sokuphila kwanamuhla, indima yezibuko ezinemibala ayikona nje ukuvikela amehlo, futhi kuwumsebenzi wobuciko.Ipheya lezibuko ezinemibala ezifanele, ezinezingubo ezifanele, lingakwazi ukuphazamisa isimo sengqondo esingavamile somuntu.
Bona amalensi e-chromatic
Ukusabela kwelensi eshintsha umbala ekukhanyeni kuthintwa izinga lokushisa.Ukwehlisa izinga lokushisa kushintsha "umsebenzi" wokusabela kwe-photochromic, kwehlisa ukusabela kokuhlanganiswa kabusha - ukusabela lapho ilensi ibuyisela ukukhanya - futhi ibambezela isikhathi sokushintsha umbala.Ngokuvumelana nalokho, yiba sendaweni enezinga lokushisa eliphansi, shintsha izibuko zombala zikhanyiswa ukukhanya, shintsha umbala ube mkhulu, ubonakale umnyama ngokumnyama.
Ngenxa yokuthi i-halide yesiliva eyengeziwe ihlanganiswe ne-optical material, ngakho-ke izibuko ze-discoloration zingaphinda ziphindwe, ukusetshenziswa kwesikhathi eside, hhayi kuphela ukuvikela amehlo ekuvuseleleni ukukhanya okunamandla, kodwa futhi kudlala indima ekulungiseni umbono.
Thola amandla nobuthakathaka
Isibuko sonwabu sishintsha umbala ngokuzenzakalelayo ngokuya ngokushintsha kokukhanya kwelanga, ukuze sivikele amehlo, sithuthukise umuzwa wobuhle, futhi sinciphise ukugqugquzelwa nokulimala kokukhanya kwelanga nemisebe ye-ultraviolet emehlweni.Uma ukhetha i-lens ye-chameleon, akuwona umqondo omuhle ukukhetha kuphela umbala ofanele hhayi amalensi wekhwalithi engcono kakhulu.Izibuko eziningi ezisezingeni eliphansi zithengiswa emakethe, izibuko ezimahhadlahhadla ngaphandle kokucutshungulwa ngokunemba nokuhlolwa okufanelekile, ngemva kokugqoka, ungenza ubone ukuhlanekezelwa kwento, umbono wokusetshenziswa, ukukhathala kwamehlo, ukubangela izifo zazo zonke izinhlobo zamehlo.
(1) Ikhwalithi ephezulu yombala oshintsha indawo yengilazi yelensi, akukho mihuzuko, imihuzuko, indawo enoboya, umgodi, ilensi etshekile ekubonweni kokukhanya, isiphetho esiphezulu.Ayikho indawo, itshe, umugqa, ibhamuza, ukuqhekeka ngaphakathi kwelensi, okusobala nokukhanyayo.
(2) ama-lens amabili ezibuko ezishintsha umbala kufanele abe nombala ofanayo ngaphandle komehluko we-lens, ukushintsha kombala kufanele kube iyunifomu, ayikwazi ukukhombisa imibala eminingana, akukho "umbala we-Yin no-Yang";Lapho nje ubona ukukhanya kwelanga, isikhathi sokushintsha umbala siyashesha, futhi lapho kungenakukhanya kwelanga, isikhathi sokufiphala naso siyashesha.Ilensi ephansi ishintsha umbala kancane, umbala ufiphele ngokushesha, noma ushintshe umbala ngokushesha, umbala unyamalale kancane.Izibuko ezishintsha umbala ezimbi kakhulu azinambala nhlobo.
(3) Ubukhulu bama-lens amabili we-chameleon kufanele buhambisane, hhayi owodwa obukhulu futhi owodwa omncane, ngaphandle kwalokho, kuzothinta umbono futhi kulimaze impilo yamehlo.Ubukhulu besiqephu esisodwa kufanele bufane.Uma kuyilensi eyisicaba eshintshe umbala, ubukhulu kufanele bube ngu-2mm futhi unqenqema lube bushelelezi.
(4) Lapho ugqoke, akukho umuzwa, akukho isiyezi, akukho ukuvuvukala iso, observation izinto azifiphaziwe, akukho deformation.Lapho uthenga, thatha izibuko esandleni, bheka izinto ezikude ngeso elilodwa ngokusebenzisa ilensi, nyakazisa ilensi ukusuka ohlangothini ukuya phezulu naphansi, izinto ezikude akufanele zibe nenkohliso yokunyakaza.
(5) ukushintsha umbala fast: high unwabu, has a impendulo ngokushesha imvelo, unwabu in the imisebe yelanga imizuzu engaba ngu-10, okungukuthi, kufanele sifinyelele esiphezulu umbala ukujula, ngaphandle kwalokho umbala izinga eliphansi.Izibuko eziye zashintsha umbala ngaphansi kwesibani se-fluorescent zithuthelwa ebumnyameni, futhi isikhathi sokubuyiswa kwe-lens asikho ngaphezu kwemizuzu engu-20 ye-chameleon yekhwalithi ephezulu.
(6) Ukuvikela, ilensi yonwabu yekhwalithi ephezulu, ingavimba i-UV A UV B ngo-100%, ukuze ogqokile anikeze isivikelo se-UV esisebenza kahle kakhulu.
Unwabu kuphela oluhlangabezana nezidingo ezingenhla lusezingeni eliphezulu.
