Dichroic iavtuaj yeem tso saib ntau yam xim hauv qab teeb pom kev sib txawv. Nws yog cov khoom siv iav tshwj xeeb. Nws yog cov iav uas tsis yog-translucent. Ua los ntawm stacked txheej ntawm hlau oxide. Qhov no yog vim li cas nws muaj cov xim sib txawv hauv cov ces kaum sib txawv. Lub npe lag luam "dichroic" tuaj yeem qhia peb lossis ntau dua xim (tricolor). Qee zaum, nws tuaj yeem pom cov xim zaj sawv. Nws cov khoom siv kho qhov muag tshwj xeeb ua rau nws siv dav hauv kev kos duab, kev tshawb fawb thiab thev naus laus zis.
Keeb kwm thaum ntxov ntawm dichroic iav
Ancient khoom siv tes ua
Lub tswvyim ntawm dichroic iav hnub rov qab mus rau ancient civilizations. Raws li thaum ntxov raws li lub teb chaws Ottoman Roman, artisans tau mastered txheej txheem ntawm ua iav nrog dichroic teebmeem. Piv txwv li, lub npe nrov Lechugus khob. Qhov no yog Roman iav los ntawm lub xyoo pua plaub. Lub khob yog carved los ntawm ib qho khoom siv thiab yog ib qho ntawm ob peb ua tiav iav los ntawm lub sijhawm. Nws yog dichroic iav, uas tuaj yeem tshwm ntsuab thaum nruab hnub thiab liab thaum hmo ntuj. Koj tuaj yeem txaus siab rau qib sib txawv ntawm kev zoo nkauj ntawm txhua lub kaum sab xis. Cov nyhuv dichroic no ua tiav los ntawm kev ntxiv cov hlau me me rau lub khob. Cov khoom no tuaj yeem tsim kev cuam tshuam los ntawm irradiation ntawm lub teeb, yog li qhia cov nyhuv dichroic.
Medieval kev loj hlob
Nrog txoj kev loj hlob ntawm Lub Sijhawm, mus rau Nruab Nrab Hnub nyoog. Dichroic iav tshuab kuj tau tsim ntxiv. Cov kws txawj siv thev naus laus zis hauv cov iav stained Windows ntawm pawg ntseeg. Txhawm rau kom muaj xim sib txawv thiab pom cov teebmeem. Cov iav no zoo nkauj ob qho tib si sab hauv thiab sab nraud. Lub cam khwb cia duab ntxoov ntxoo kuj muaj yeeb yuj, ntxiv ib qho kev kos duab tshwj xeeb rau kev kho kom zoo nkauj ntawm lub tsev teev ntuj, ua rau lub tsev teev ntuj muaj zog thiab muaj zog.
Stained glass Windows tsis yog tsuas yog zoo nkauj xwb, tab sis kuj tseem muaj kev ntseeg thiab kev kawm tseem ceeb. Stained glass Windows kuj tseem ceeb iav cim ntawm lub sijhawm ntawd. Qee lub tsev teev ntuj nto moo, xws li Notre Dame Cathedral hauv Paris thiab Milan Cathedral, yog nto moo rau lawv qhov zoo nkauj stained iav qhov rais. Nws tsis yog tsuas yog ib qho kev nthuav qhia ntawm medieval prowess. Nws kuj yog ib qho cuab yeej cuab tam tseem ceeb ntawm lub sijhawm ntawd. Niaj hnub no, nws yog tseem attracts ntau tourists.
Lub hnub yug ntawm niaj hnub dichroic iav
Kev tawg ntawm lub xyoo pua 20th
Qhov kev tawg tiag tiag hauv niaj hnubiav dichroictuaj nyob rau xyoo 1960. Thaum lub sij hawm, NASA cov kws tshawb fawb tau ua haujlwm ntawm kev ua haujlwm siab kho qhov muag thiab cov ntaub ntawv tiv thaiv. Cov txheej txheem txheej txheej txheej txheej txheej txheej tshiab tau tsim. Cov thev naus laus zis tau tsim los rau kev siv aerospace. Feem ntau yog lub qhov rais thiab ntsuas vaj huam sib luag ntawm lub dav hlau. Txhawm rau tiv thaiv cov khoom siv los ntawm kev cuam tshuam ntawm lub hnub ci hluav taws xob hnyav.
NASA pab nyiaj
NASA pab pawg tshawb fawb suav nrog cov kws kho qhov muag thiab cov kws tshawb fawb cov ntaub ntawv. Lawv nrhiav pom cov nyhuv dichroic los ntawm kev sib tsoo thaum tswj cov kev xav thiab kev sib kis ntawm lub teeb hauv lawv cov kev tshawb fawb ntawm multilayer txheej tshuab. Qhov kev tshawb pom no tau coj lawv mus kawm ntxiv thiab txhim kho cov txiaj ntsig. Kev cia siab yog tias cov ntaub ntawv sib txawv tuaj yeem tsim tau raws li qhov txiaj ntsig no.
Vim hais tias cov khoom pob tshab zoo tib yam tsis tuaj yeem tiv thaiv tib neeg lub zeem muag los ntawm cov kab hluav taws xob hnyav ntawm lub hnub ci. Cov khoom siv xws li tib neeg lub cev mus rau lub dav hlau thiab khoos phis tawj tuaj yeem raug mob los ntawm hnub ci hluav taws xob yog tias tsis muaj kev tiv thaiv. Dichroic iav, vim tias nws muaj cov kab ntau ntawm cov hlau, tuaj yeem thaiv qhov kev puas tsuaj ntawm lub hnub ci zog. Yog li pab pawg tshawb fawb nws thiaj li tsim cov iav dichroic hauv kev xav niaj hnub no. Cov khoom siv tshiab tuaj yeem pom cov xim sib txawv hauv cov teeb pom kev sib txawv. Nws muaj qhov tshwj xeeb kho qhov muag.
