Uma izulu lishisa, bayanda abantu abakhetha ukufaka izibuko zelanga ukuze bavikele amehlo abo.Izibuko zelanga ezivamile zihlukaniswe zibe tinted futhi polarized.Noma ngabe abathengi noma amabhizinisi, izibuko zelanga ezihlukanisiwe azijwayelekile.
Incazelo Of Polarization
I-polarization, eyaziwa nangokuthi ukukhanya kwe-polarized, ibhekisela ekukhanyeni okubonakalayo okuyigagasi eliguquguqukayo, elinesiqondiso sokudlidliza esiqonde lapho sisakazeka khona.Isiqondiso sokudlidliza sokukhanya kwemvelo siyathandabuza endizeni ngokuqondana nesiqondiso sokusakazeka;ngokukhanya kwe-polarized, isiqondiso sayo sokudlidliza silinganiselwe endaweni ethile ngesikhathi esithile.
I-Polarization Classification
I-polarization ingahlukaniswa ngezinhlobo ezintathu: i-polarization yomugqa, i-elliptical polarization, kanye ne-circular polarization.Ngokuvamile, lokho okubizwa ngokuthi i-polarization kubhekisela ku-polarization yomugqa, eyaziwa nangokuthi i-plane polarization.Ukudlidliza kwalolu hlobo lwegagasi lokukhanya kugxilile endleleni ethile futhi kuhlala kungashintshile.Indlela yayo yokusakazeka emkhathini ilandela ijika le-sinusoidal, futhi ukuqagela kwayo endizeni okuqonde ngqo lapho kusakazeka khona kuwumugqa oqondile.
Indiza eyakhiwe isiqondiso sokudlidliza sokukhanya kwe-polarized linearly kanye nesiqondiso sokusakazeka sibizwa ngokuthi indiza yokudlidliza, futhi indiza ehambisana nesiqondiso sokudlidliza futhi equkethe isiqondiso sokusakazeka ibizwa ngokuthi indiza ye-polarization.Ukudlulisa ukukhanya kwemvelo nge-polarizer kungaveza ukukhanya okumise okwemigqa.
Umsebenzi We-Polarization
Ekuphileni kwansuku zonke, kunemithombo eminingi yokukhanya ekhiqiza ukukhanya okuyingozi, ikakhulukazi ukukhanya kwelanga.Ukukhanya kwelanga kukhipha izinhlobo ezintathu zokukhanya: ukukhanya okubonakalayo, ukukhanya kwe-infrared, nokukhanya kwe-ultraviolet (UV).Phakathi kwalokhu, ukukhanya kwe-ultraviolet kungabangela ukulimala okukhulu esikhumbeni nasemehlweni.Ukukhanya okubonakalayo kusuka ku-380 kuya ku-780 nanometers, kuyilapho ukukhanya kwe-ultraviolet kuhlukaniswa futhi kube i-UVA, UVB, ne-UVC, ngamaza amaza angaphezu kuka-310nm.I-UVA, UVB, ne-UVC imisebe eyingozi.Ukuchayeka isikhathi eside kule misebe kungabangela umonakalo emzimbeni.I-UVB inomthelela ongathi sína embonweni, futhi “yimisebe yokushuka” eyenza isikhumba sibe mnyama.Iningi lamakhona eso limunca lolu hlobo lokukhanya kwe-UVB, ngakho-ke kubalulekile ukuvimba lo mthombo wokukhanya.
Amalensi ane-polarizedbanomsebenzi wokukhanya kwe-polarizing, okubavumela ukuba bavimbe ukukhanya okuyingozi ngaphandle kokuthinta ukudluliswa kokukhanya okubonakalayo, ngaleyo ndlela kuvikeleke amehlo.Ngokungeziwe kumsebenzi oyisisekelo wokuvikela i-UV, amalensi agqamile aphinde abe ne-anti-glare, ukuboniswa komgwaqo, nemisebenzi yokucwebezela kwamanzi, okuwenza afanelekele ukushayela, ukudoba, ukuhamba, nokugqokwa kwansuku zonke.
Ukukhiqizwa Kwamalensi Apholile
Ngomqondo ojwayelekile,ama-lens ane-polarizedngokubona eduze kunesakhiwo esifana nesemishi (ehlanganisa ungqimba lwangaphambili lwezibuko, ungqimba oluphakathi lwemicu egqamile, kanye nolwelwesi olungemuva lwamalensi abona eduze, konke kuhlanganiswe ndawonye).Izinto ezisetshenziswa kakhulu zamalensi zinenkomba ye-refractive engu-1.50 (futhi kukhona i-1.60, kodwa zibiza kakhulu).Amalensi aminyene futhi asindayo, futhi uma incwadi kadokotela idlula u-600°, kokubili ubuhle nokunethezeka kuzothinteka kakhulu.Ibanga lentengo lamalensi ahlukanisiwe okubona eduze libanzi impela futhi lincike ekuzinzeni kwenqubo yomkhiqizi kanye nekhwalithi.
Amalensi anemibala ayasiza ekuhlungeni ukukhanya okuthile okuhlakazekile (njengomthelela wokugawula wamakhethini), kodwa kunomehluko omkhulu kwikhwalithi.Amalensi apholile anekhwalithi embi athambekele ekuqhekekeni nasekuqhekekeni, futhi amaningi awahlangabezani namazinga okubona.
Izinto Zokusebenza Zamalensi Apholile
Kunezinhlobo ezine ezivamile zeama-lens ane-polarizedemakethe: amalensi engilazi, amalensi eresin, amalensi ePC, namalensi e-TAC.
① Amalensi engilazi
Nakuba zikwazi ukumelana nokuklwebheka futhi zisebenza kahle, isisindo sazo nezinkinga zokuphepha ziholele ekwehleni kokusetshenziswa kwazo.
② Amalensi e-resin
Alula ukutsheka, angasindi, futhi amelana nomthelela, okuwenza abe enye yezinto ezisetshenziswayo zezibuko zelanga ezidumile.Kodwa-ke, amalensi e-resin athambekele ekuqhekekeni ngesikhathi senqubo yokuhlanganisa, futhi asengabeka izingozi zokuphepha uma ebhekene nomthelela omkhulu.
③ amalensi e-TAC
I-TAC ingenye yezinto ezibonakalayo zamangqamuzana aphezulu.Amalensi e-TAC njengezibuko zelanga anezici ezifana nokumelana ne-asidi ne-alkali, angasindi, kanye nokusebenza kahle kwezindleko eziphezulu.Kodwa-ke, amalensi e-TAC anokumelana nokuhuzuka okubi kanye nezici zokungaboni ezingazinzile.Naphezu kwentengo yabo ephansi, baye bashiywa iningi lemikhiqizo yangaphandle eyaziwayo.
④ PC lens
Ayisindi, anokuthayela okuhle, futhi aqinile ukumelana nomthelela, okuwenza abize kakhulu.
Amalensi e-PC anqoba ingcindezi eyindilinga kanye nezinkinga ze-astigmatism ezibangelwa ukuwohloka kwamalensi endabuko e-TAC ngemva kokufakwa kuhlaka.Anamandla okumelana nomthelela (izikhathi ezingama-60 kunamalensi engilazi, izikhathi ezingama-20 kunamalensi e-TAC, kanye nezikhathi eziphindwe ka-10 kunamalensi eresin) futhi asetshenziswa kakhulu endaweni yasemkhathini nasezinkundleni zempi.Ngesikhathi esifanayo, amalensi e-PC alula, angu-37% alula kunamalensi eresin avamile.
Umehluko PhakathiAmalensi agqamileNama-Tinted Lens
Amalensi anombala asebenzisa kuphela umsebenzi wokunciphisa ukukhanya, futhi awakwazi ukuhlunga ukukhanya.Zinganciphisa kuphela ukushuba kokuxhopha, ukukhanya kwe-ultraviolet, njll., futhi azikwazi ukuvimba ngokuphelele le misebe yokukhanya eyingozi.Ngesikhathi esifanayo, ngenxa yokukhanya okuncishisiwe, kuthinta ukudluliswa kwama-lens, okwenza ingozi yokuphepha kwabagqoki.
