Kwizicelo ze-optical—ingakumbi ekuvelisweni kweelensi, izihluzi, izibonisi, kunye nezinto zokuhombisa ze-optical—ulawulo lokuphambuka kombala luye lwaba yindlela ebalulekileyo yokulinganisa ukuqinisekisa ukuhambelana kwemveliso kunye nokusebenza okubonakalayo. Ukuphambuka kombala ikakhulu kuvela kubukhulu befilimu obungalinganiyo, ukutshintsha kwe-refractive index, kunye nokuguquguquka kwenkqubo. Ke ngoko, ukuba nobuchule bokulawula obusebenzayo kubalulekile ekuphuculeni umgangatho we-optical coating.
Iindlela zokuphambuka kombala zeNombolo 1
Iingubo ezibonakalayo zihlala zifakwa ngokuphuma kobushushu okanye ukutshiza ngemagnetron, zenze ii-stacks ezininzi. Ubukhulu befilimu kunye ne-refractive index zichaphazela ngokuthe ngqo ukukhanya kunye nokudluliselwa kwiindidi ezahlukeneyo zamaza, ngaloo ndlela zichaphazela umbala obonwayo. Iindlela eziphambili ziquka:
Utshintsho loBungqingqwa beFilimu: Izinga lokufakwa kwefilimu elingalinganiyo okanye ukujikeleza/ukulungisa okungafanelekanga kwe-substrate kukhokelela kumahluko kubukhulu bendawo, okutshintsha iziphumo zokuphazamiseka kwe-optical.
Utshintsho lweSikhombisi sokuKhangela: Utshintsho kubunyulu bezinto, ukwakheka kwegesi, okanye ubushushu be-substrate lunokutshintsha i-refractive index, nto leyo ekhokelela ekutshintsheni kombala wokukhanga/ukudluliselwa.
Ukudibanisa Ukuphazamiseka Kwee-Multilayer: Kwii-stacks zesihluzi ezikhanyayo kakhulu okanye eziphazamisayo, iimpazamo zobukhulu ziyaqokelelana, nto leyo ebangela utshintsho oluphezulu lokuphazamiseka olubonakala njengokuphambuka kombala.
Inombolo 2.Umbala Wokugquma ObonakalayoIindlela zoLawulo
1. Ulawulo loButyebi obuchanekileyo
Iinkqubo zokujonga i-Quartz Crystal Microbalance (QCM) okanye iinkqubo zokujonga ezibonakalayo zisetyenziselwa ukulinganisa ubungakanani kunye nobukhulu ngexesha langempela.
Iinkqubo zolawulo ezivaliweyo zilungisa amandla omthombo wokufuma okanye umsinga wethagethi yokutshiza, zigcina ukuchaneka kobukhulu ngaphakathi kwe-±1%.
2. Ukungaguquguquki kweSikhombisi sokuKhangela
Ubunyulu bezinto kunye nolawulo lwenkqubo ye-vacuum ephezulu kubalulekile ekunciphiseni ukufakwa kwegesi eseleyo kunye nokuzinzisa ii-refractive indices.
Kwizinto ezisabelayo ezifana neTiO₂ kunye neSiO₂, ulawulo lwempendulo yegesi esabelayo luqinisekisa uzinzo lwe-stoichiometric.
3. Ukuphucula Ukulingana
Ukujikeleza kwe-substrate, intshukumo yeplanethi, okanye uqwalaselo lweethagethi ezininzi kuphucula ukufana kwefilimu.
Kwiindawo ezinkulu, iithagethi zokutshiza ezinemithombo emininzi okanye ezisilinda/ezine-annular zinciphisa ukuphambuka okuphakathi ukuya kumda.
4. Ukulungiswa emva kokufakwa kwindawo
Kwizinto zokwaleka eziphazamisana ne-multilayer, i-metrology yobukhulu obusekelwe kwi-laser ingakhokela ukulungiswa kokwaleka kwakhona ukuze kuncitshiswe ukuphambuka.
Ukufakelwa kwe-thermal kuphucula uxinzelelo lwefilimu kunye nee-optical constants, kuphucula ukufana kombala.
Inombolo 3: Izicelo kunye neMisebenzi yoShishino
Kwizixhobo zokubonisa ezikumgangatho ophezulu, ii-AR/VR optics, iilensi zekhamera, kunye neefilimu zokukhanya ezihombisayo, ulawulo lokuphambuka kombala lumisela ngokuthe ngqo isivuno semveliso kunye nomgangatho wokubonakala. Umzekelo:
Iilensi ze-AR/VR zifuna iileya ezininzi ezichasene nokukhanya okubonakalayo ezinombala ofanayo kuzo zonke ii-engile zokujonga, zifuna ukuchaneka kobukhulu ngaphakathi kwe-±2 nm.
Izihluzi zesikrini eziquka iileya zesalathisi eziphezulu nezisezantsi ezitshintshanayo zinobuthathaka kakhulu kutshintsho lombala, zifuna ukufana okuchanekileyo kunye nozinzo lwesalathisi.
Ulawulo lokuphambuka kombala kwiingubo ze-optical luxhomekeke ekuchanekeni kobukhulu befilimu, uzinzo lwe-refractive index, kunye nokwenza ngcono ukufana. Ngokudibanisa i-QCM okanye ukujonga okubonakalayo, ukuphucula inkqubo ye-vacuum, ukubeka imithombo emininzi, kunye nokulungiswa kokufakwa emva kokufakwa, abavelisi banokufikelela ekuhambelaneni kombala okuphezulu. Ezi ndlela aziqinisekisi kuphela ukusebenza okubonakalayo kodwa zikwaphucula umgangatho wokubonakala kwemveliso yokugqibela kunye nokukhuphisana kwimarike.
