Kwimimandla echanekileyo kakhulu efana ne-optoelectronics, iteknoloji yokubonisa, kunye nezixhobo ze-optical, igama elithi "ifilimu ebhityileyo ye-optical" livela rhoqo. Ezi ngubo zichaphazela ngokuthe ngqo izalathisi zokusebenza eziphambili ezifana nokudluliselwa, ukubonakaliswa, kunye nokuboniswa kombala, kwaye ekugqibeleni zibumba amava okubona kunye nemveliso yokusebenza yemveliso yokugqibela. Kodwa zithini kanye kanye iifilimu ezibhityileyo ze-optical, kwaye zifezekisa njani ukulawulwa kokukhanya okuchanekileyo ngokusebenzisa ubuchwepheshe obuphambili bokugquma? Eli nqaku linika isishwankathelo sobugcisa.
Zithini iiFilimu eziThin ze-Optical?
Iifilimu ezibhityileyo ze-Optical zibhekisa kwiingubo ezisebenzayo ezinobukhulu obuqala kwii-nanometers ukuya kwii-micrometers, ezihlala zibekwe kwiglasi, iplastiki, okanye ii-substrates zesinyithi kusetyenziswa ubuchwepheshe bokugquma nge-vacuum obufana nokuphuma kobushushu, ukutshiza nge-magnetron, okanye ukufakwa kwe-electron beam. Ezi filimu zinokuba nomaleko omnye okanye iileya ezininzi ezihlanganisiweyo, nganye inee-indices ezahlukeneyo zokukhanya kunye nobukhulu, ezenzelwe ukufezekisa iziphumo ezithile zokukhanya.
Imigaqo esisiseko: Ukuphazamisa kunye nokuCima
Eyona ndlela iphambili emva kweefilimu ezibhityileyo ze-optical kukuphazamiseka kwe-optical. Xa ukukhanya kudibana nomphezulu wefilimu ebhityileyo, kubonakaliswa kancinci kwaye kuphinde kuguqulwe kwi-interface nganye. Ngenxa yobukhulu befilimu elawulwayo kunye ne-refractive indices ezahlukeneyo phakathi kweeleya, imisebe ebonakalisiweyo inokuphazamisana ngendlela eyakhayo okanye etshabalalisayo, kuxhomekeke kumahluko wesigaba sayo.
Umzekelo:
Xa ubukhulu befilimu buyilwe ngendlela yokuba amaza abonakalisiweyo arhoxise omnye komnye, iziphumo ezichasene nokukhanya ziyafezekiswa—ezisetyenziswa kakhulu kwiilensi okanye kwiglasi yokugubungela i-photovoltaic.
Ngokwahlukileyo koko, xa amaza abonakalisiweyo ekwisigaba, ayaqinisana, evelisa ukuhluza okuphezulu okanye ukukhetha ubude be-wavelength—njengoko kubonakala kwi-beam splitters, kwi-laser mirrors, okanye kwii-optical filters.
Olu hlengahlengiso lobude bendlela yokukhanya lusembindini woyilo lwefilimu encinci, apho ubukhulu buhlala buyikota yobude bomda ekujoliswe kuwo (λ/4) okanye ii-multiples zayo, okuvumela ulawulo oluchanekileyo kwiibhendi ezithile ze-spectral.
Iintlobo eziqhelekileyo zeengubo zokukhanya
Iingubo Ezingakhanyisiyo (iingubo ze-AR): Zithintela ukubonakaliswa komphezulu kwaye ziphucule ukuhanjiswa. Zisetyenziswa kakhulu kwiilensi zeglasi, iikhamera, kunye neephaneli zokuchukumisa.
Iingubo Ezibonisa Ukukhanya Okuphezulu (iingubo ze-HR): Khulisa ukubonakalisa ukukhanya kwiiwavelengths ezijoliswe kuzo, ezisetyenziswa kwizibuko ze-laser, ekukhanyiseni kwesiteji, nakwi-precision optics.
Iingubo ze-Optical Filter: Zithumela okanye zivale uluhlu oluthile lwamaza ombane. Zifumaneka kwiisensa, izixhobo ze-optical, kunye nezixhobo ze-telecom.
Iifilimu eziHlanganisa imisebe/eziHlanganisa imisebe: Ukukhanya okwahlulwe ngokwe-wavelength okanye imeko ye-polarization, esetyenziswa kwimiboniso, iiprojektha, kunye nee-automotive head-up displays (ii-HUD).
Uyilo kunye nokuVeliswa kweeFilimu eziThin ze-Optical
Iifilimu ezibhityileyo ze-optical ezisebenza kakuhle azifuni kuphela ukhetho oluchanekileyo lwezinto ezibonakalayo kodwa zikwafuna noyilo oluntsonkothileyo lwemaleko kunye nolawulo lwenkqubo. Ubuchwepheshe bokubeka izinto obusetyenziswa kakhulu ngoku buquka:
Ukufuma kobushushu
Ukufuma kwe-Electron Beam (E-Beam)
Ukutshiza ngeMagnetron
Ukufakwa kwe-Ion-Assisted Deposition (IAD)
Ezi ndlela zivumela ukuchaneka kobukhulu besikali se-nanometer kwaye ziqinisekisa iipropati ezifanayo zokukhanya kuzo zonke iindawo ezinkulu.
Ngokwenyani, iifilimu ezibhityileyo ze-optical zisebenza ngokuguqula ukusasazeka kokukhanya ngokuphazamiseka, okuvumela ukuphuculwa, ukuncitshiswa, ukucoca, okanye ulawulo lwe-polarisation. Ezi coating zidibanisa i-physical optics, isayensi yezinto, kunye nokubekwa kwe-vacuum ngokuchanekileyo kwitekhnoloji enye edibeneyo, edlala indima ebalulekileyo kumashishini okuvelisa e-photonic anamhlanje kunye namashishini aphezulu. Njengoko imfuno ikhula kwiinkqubo ze-optical ezisebenzayo kakhulu, ezilahlekayo kancinci, kunye neenkqubo ze-optical ezixineneyo, uphuhliso oluqhubekayo kubuchwepheshe be-thin-film luya kuqhubeka nokuqhuba inkqubela phambili kwezoshishino.
