Xa imozulu ishushu, baya besanda abantu abakhetha ukunxiba iindondo zelanga ukuze bakhusele amehlo abo. Iindondo zelanga eziqhelekileyo zohlulwe zibe zi-tinted kunye ne-polarized. Nokuba ngabathengi okanye ngamashishini, iiglasi zelanga ezipholileyo aziqhelekanga.
Inkcazo yePolarization
I-polarization, ekwabizwa ngokuba kukukhanya kwepolarized, ibhekisa kukukhanya okubonakalayo kube ngamaza anqamlezayo, kunye nesalathiso saso sokungcangcazela sijonge kwicala losasazo. Isalathiso sokungcangcazela kokukhanya kwendalo akunamkhethe kwinqwelomoya ye-perpendicular ukuya kwicala lokusasaza; Ukukhanya kwe-polarized, isalathiso sayo sokungcangcazela silinganiselwe kwicala elithile ngexesha elithile.
Ukuhlelwa kwePolarization
I-polarization inokwahlulwa ibe ziindidi ezintathu: i-polarization yomgca, i-elliptical polarization, kunye ne-circular polarization. Ngokuqhelekileyo, into ebizwa ngokuba yi-polarization ibhekisela kwi-polarization yomgca, eyaziwa ngokuba yi-plane polarization. Ukungcangcazela kolu hlobo lwamaza okukhanya kulungiswe ecaleni kwendlela ethile kwaye kuhlala kungatshintshi. Indlela yayo yokusasaza esithubeni ilandela igophe le-sinusoidal, kwaye ingqikelelo yayo kwinqwelomoya ejonge kwicala lokusasaza ngumgca othe ngqo.
Inqwelomoya eyenziwe yindlela yokungcangcazela yokukhanya okucandekileyo ngokwemigca kwaye isalathiso sokusasaza sibizwa ngokuba yindiza yokungcangcazela, kunye nenqwelomoya ejonge kwicala lokungcangcazela kwaye iqulathe isalathiso sokusasaza ibizwa ngokuba yindiza yepolarization. Ukudlula ukukhanya kwendalo kwi-polarizer kunokuvelisa ukukhanya kwe-linearly polarized.
Umsebenzi wePolarization
Kubomi bemihla ngemihla, kukho imithombo emininzi yokukhanya evelisa ukukhanya okuyingozi, ngakumbi ukukhanya kwelanga. Ukukhanya kwelanga kuvelisa iintlobo ezintathu zokukhanya: ukukhanya okubonakalayo, ukukhanya kwe-infrared, kunye nokukhanya kwe-ultraviolet (UV). Phakathi kwezi, ukukhanya kwe-ultraviolet kunokubangela ingozi enkulu kwesikhumba namehlo. Ukukhanya okubonakalayo kuphakathi kwe-380 ukuya kwi-780 nanometers, ngelixa ukukhanya kwe-ultraviolet kusahlulwe ngakumbi kwi-UVA, i-UVB, kunye ne-UVC, kunye nobude obungaphezulu kwe-310nm. I-UVA, UVB, kunye ne-UVC yimitha eyingozi. Ukuhlala ixesha elide kule mitha kunokubangela umonakalo emzimbeni. I-UVB inefuthe elibi embonweni, kwaye ikwayi "ray yokutshisa" eyenza mnyama ulusu. Uninzi lweekona zamehlo lufunxa olu hlobo lokukhanya kwe-UVB, ngoko ke kubalulekile ukuvala lo mthombo wokukhanya.
Iilensi zepolarizedbanomsebenzi wokukhanya kwe-polarizing, okubavumela ukuba bathintele ukukhanya okuyingozi ngaphandle kokuchaphazela ukuhanjiswa kokukhanya okubonakalayo, ngaloo ndlela bekhusela amehlo. Ukongeza kumsebenzi osisiseko wokukhusela i-UV, iilensi ezipolarized zikwanazo ne-anti-glare, imbonakalo yendlela, kunye nemisebenzi ye-glare surface yamanzi, ezenza zilungele ukuqhuba, ukuloba, ukuhamba kunye nokunxiba imihla ngemihla.
Ukuveliswa kweeLensi eziPolarized
Ngokwabantu abaqhelekileyo,iilensi ezipholileyoUkubona kufutshane kunesakhiwo esifana nesandwich (ebandakanya umaleko wangaphambili weendondo zelanga, umaleko ophakathi weentsinga ezipholileyo, kunye nomqolo weelensi ezibona kufutshane, zonke ezilaminethiweyo kunye). Isixhobo se-lens esisetyenziswa ngokuqhelekileyo sine-index ye-refractive ye-1.50 (kukho kwakhona i-1.60, kodwa zibiza kakhulu). Iilensi zinobunzima kwaye zinzima, kwaye ukuba i-prescription idlula i-600 °, zombini i-aesthetics kunye nentuthuzelo iya kuchaphazeleka kakhulu. Uluhlu lwexabiso lelensi eziphothiweyo zokujonga kufutshane lubanzi kwaye luxhomekeke kwinkqubo yomenzi wemveliso uzinzo kunye nomgangatho.
Iilensi zepolarized ziluncedo ekuhluzeni ukukhanya okuthe saa (okufana nefuthe le-grating yeemfama), kodwa kukho umahluko omkhulu kumgangatho. Iilensi zepolarized ezikumgangatho ophantsi ziqhelene nokuqhekeka kunye nokuqhekeka, kwaye uninzi aluhambelani nemigangatho yokubona.
IiMathiriyeli zeeLensi eziPolarized
Kukho iintlobo ezine eziqhelekileyo zeiilensi ezipholileyokwimarike: iilensi zeglasi, iilensi zeresin, iilensi zePC, kunye neTAC.
① Iilensi zeglasi
Nangona zikwazi ukumelana nokukrwempa kwaye zisebenza kakuhle, ubunzima bazo kunye nemiba yokhuseleko ikhokelele ekwehleni kokusetyenziswa kwazo.
② Iilensi zeresin
Zilula ukwenza i-tint, zikhaphukhaphu, kwaye ziyakwazi ukumelana nempembelelo, zizenza enye yezinto eziphambili kwiindondo zelanga ezidumileyo. Nangona kunjalo, iilensi ze-resin zithande ukutshiphuzwa ngexesha lenkqubo yokuhlela, kwaye zisenokwenza iingozi zokhuseleko xa ziphantsi kwempembelelo enkulu.
③ iilensi ze-TAC
I-TAC sesinye semathiriyeli ecacileyo ephezulu yeemolekyuli. Iilensi ze-TAC njengeeglasi zelanga zineempawu ezifana ne-asidi kunye nokumelana ne-alkali, ukukhaphukhaphu, kunye nokusebenza kakuhle kweendleko. Nangona kunjalo, iilensi ze-TAC zinokuxhathisa okulambathayo kunye neempawu zamehlo ezingazinzanga. Nangona ixabiso labo eliphantsi, baye bashiywa uninzi lweempawu zangaphandle ezaziwayo.
④ Iilensi zePC
Zikhaphukhaphu, zinentsebenzo entle ye-tinting, kwaye zinamandla okumelana nefuthe, nto leyo ezenza zibiza kakhulu.
Iilensi zePC zoyisa uxinzelelo olungqukuva kunye neengxaki ze-astigmatism ezibangelwa kukuguqulwa kweelensi ze-TAC zemveli emva kokwakhiwa. Zinempembelelo enamandla yokuxhathisa (amaxesha angama-60 eelens zeglasi, amaxesha angama-20 eelens ze-TAC, kunye namaxesha ali-10 eelensi zeresin) kwaye zisetyenziswa kakhulu kwi-aerospace kunye nemimandla yomkhosi. Kwangaxeshanye, iilensi zePC zikhaphukhaphu, zikhaphukhaphu ngama-37% kunezona ziqhelekileyo iilensi zeresin.
Umahluko PhakathiIiLensi eziPolarizedkunye neeLensi eziTinted
Iilensi ezifakwe umbala zisebenzisa kuphela umsebenzi wokunciphisa ukukhanya, kwaye azikwazi ukuhluza ukukhanya. Banokunciphisa kuphela ubunzulu be-glare, ukukhanya kwe-ultraviolet, njl., kwaye abanako ukuvala ngokupheleleyo le mitha yokukhanya eyingozi. Ngexesha elifanayo, ngenxa yokukhanya okuncitshisiweyo, kuchaphazela ukuhanjiswa kweelensi, kubeka ingozi yokhuseleko kubathwali.
