Amafasitela e-Sapphire Optical enziwe ngokwezifiso i-High Purity Transmittance ≥90% Isithombe Esivelele

Incazelo emfushane:

Amafasitela e-sapphire optical ayizingxenye ezikhethekile ze-optical ezenziwe nge-single-crystal aluminium oxide (Al₂O₃), eyaziwa ngokusebenza kwawo okumangalisayo kwe-optical, amandla omshini, kanye nokuqina kwamakhemikhali. Njengoba kuyi-oxide crystal enzima kakhulu (ubulukhuni be-Mohs 9), amafasitela e-sapphire abonisa ukudlulisa okuhle kakhulu (~83-85% okungagqokwanga) ku-ultraviolet (200nm) kuya ku-mid-infrared (5.5μm) spectra, okwenza afaneleke kakhulu ekusetshenzisweni okudinga ukukhanya okuphezulu kanye nokuqina.

Ukukhiqiza kuhilela izinqubo ezibalulekile ezifaka phakathi ukukhula kokuqondiswa kwekristalu, ukuhlukaniswa ngokunemba, ukupholisha kwe-nanoscale, kanye nokugqoka okukhethekile. Amasu okukhula athuthukisiwe (isb., izindlela ze-HEM noma ze-KY) akhiqiza ama-boule asezingeni eliphezulu anobuningi obuphansi besici (<10⁴/cm²). Isakhiwo sekristalu esiyingqayizivele esinama-hexagonal senza izakhiwo ze-anisotropic, ngokuqondiswa okulungiselelwe (ukusika kwe-C-axis, i-A-axis, noma i-R-plane) okuvumela ukusebenza kwe-optical kwezinhlelo zokusebenza ezithile.

Izici Eziyinhloko

1. Ukuzivumelanisa Nezimo Ezinkulu
Amafasitela e-sapphire optical abonisa ukusebenza okuhle kakhulu ngephuzu lokuncibilika elingu-2053°C, agcina ubuqotho besakhiwo ezindaweni zokusebenza eziqhubekayo ezingu-1000°C. Lokhu kuzinza kokushisa kuvunyelwa yi-coefficient ephansi kakhulu yokwanda kokushisa (CTE) engu-5.3×10⁻⁶/K eceleni kwe-C-axis, ephakeme kakhulu kunezingilazi ze-optical ezivamile. Ngokwekhemikhali, amafasitela e-sapphire optical abonisa ukungangeni kahle okuphawulekayo, amelana nawo wonke ama-asidi aqinile (ngaphandle kwe-HF) nama-alkali, okwenza afaneleke kakhulu emishinini yokucubungula amakhemikhali kanye nezinhlelo zasolwandle. Ngokwemishini, lawa mafasitela anamandla okuguquguquka angaphezu kwe-1000MPa (anamandla ngokuphindwe ka-5-8 kunengilazi ye-optical ejwayelekile) ngokumelana okuphawulekayo komthelela.

2. Izinzuzo Zokusebenza Ezibonakalayo
Amafasitela e-sapphire optical ahlinzeka ngokudluliselwa okungu->80% kububanzi obubanzi be-spectral (200-5500nm ngobukhulu obungu-2mm). Ngokusebenzisa ukuqondiswa kwekristalu okulungiselelwe (isb., i-C-axis eqondile endleleni yokukhanya), imiphumela ye-birefringence incishiswa ngempumelelo. Ikhwalithi yendawo ihlangabezana nezidingo zokukhanya eziqinile nge-λ/10 flatness ku-633nm kanye ne-surface roughness <0.5nm RMS.

3. Amakhono Okukhiqiza Athuthukisiwe
Amafasitela ethu e-sapphire optical asekela ukucutshungulwa kwefomethi enkulu (>300mm ububanzi) kanye namajiyometri ayinkimbinkimbi kufaka phakathi ukucushwa kwe-aspheric kanye nezinyathelo. Ubuchwepheshe obukhethekile bokuvala umphetho bufinyelela amazinga okuvuza <1×10⁻⁹Pa·m³/s kwezicelo ze-vacuum. Ngezimbozo ze-carbon efana nedayimane (DLC), umkhawulo womonakalo obangelwa yi-laser (LIDT) ufinyelela ku-15J/cm² (1064nm, 10ns pulses).

Izicelo Eziyinhloko

1. Ukuzivikela kanye nezindiza
Amafasitela e-sapphire optical asebenza njengezindawo zokufaka izikhali, amelana nokushaqeka okukhulu kokushisa (>1000°C) ngesikhathi sokundiza kwe-hypersonic. Izinhlobo zebanga lesikhala ziqinisekisa impilo yenkonzo ye-orbital yeminyaka engaphezu kwengu-15 ekusetshenzisweni kwezindiza zasemkhathini.

2. Imishini Yezimboni
Ekwenziweni kwe-semiconductor, amafasitela e-sapphire optical asebenza njengezindawo zokubukela ezingamelani ne-plasma emakamelweni e-etch kanye ne-CVD. Ama-endoscope okushisa okuphezulu asebenzisa lawa mafasitela ukuze athwebule izithombe ezicacile ezindaweni zesithando somlilo ezingu-1500°C.

3. Izinsimbi Zesayensi
Amafasitela e-sapphire optical ahlanzekile kakhulu (<5ppm impucuko) anciphisa ukumuncwa kwe-X-ray kuma-synchrotron beamlines. Ukungalungi kwawo okuphansi kugcina ukuthembeka kwe-femtosecond pulse ezinhlelweni ze-laser ezisheshayo.

4. Amadivayisi Ezentengiselwano
Amafasitela angaphansi kolwandle asebenzisa amafasitela e-sapphire optical alinganiswe ukujula okungu-6000m (>60MPa). Amakhamera e-smartphone ahlanganisa lawa mafasi njengezembozo zokuvikela, esebenzisa ukumelana kwawo nokuklwebheka kwe-Mohs 9 ukuze aqine kakhulu.

Amafasitela e-sapphire optical ayaqhubeka nokwandisa izinhlelo zawo zokusebenza ngokuthuthuka ekucutshungulweni kwefomethi enkulu, amajiyometri ayinkimbinkimbi, kanye nezici zokusebenza ezithuthukisiwe, okuqinisa isikhundla sawo njengezingxenye ezibalulekile ezimbonini zobuchwepheshe obuphezulu.

Izinsizakalo ze-XKH

Ipulatifomu yesevisi ephelele ye-XKH ihlanganisa ubuchwepheshe bokukhiqiza obusezingeni eliphezulu nokusekelwa okuqinile kwezobuchwepheshe ukuze kulethwe izixazululo zamafasitela e-sapphire optical kusukela ekuqaleni kuze kube sekupheleni. Uphiko lokukhiqiza ngokwezifiso lunikeza ukucutshungulwa okusekelwe ekudwebeni ngamakhono okuguqula amafayela e-2D/3D aphelele, ahambisana nezinsizakalo zokwenza ngcono i-Design for Manufacturing (DFM) ezinciphisa izingozi zokukhiqiza kanye nezindleko. Sigcina amakhono okulingisa okusheshayo ahamba phambili embonini, sinikeza amasampula asebenzayo e-Φ100mm zingakapheli izinsuku ezi-5 zebhizinisi ukuze kusheshiswe imijikelezo yokuthuthukiswa komkhiqizo. Ukwelashwa okusebenzayo okuthuthukisiwe kufaka phakathi ukumbozwa okuqondile okuhambisana nokumelana neshidi okungashintshwa kusuka ku-10-1000Ω/□ kwezinhlelo zokusebenza zokuvikela i-EMI, kanye namafilimu azimele okulwa nenkungu agcina ukucaca kokukhanya ezindaweni ezinomswakama ophezulu.

Ingqalasizinda yokusekela ubuchwepheshe ifaka ithimba lobunjiniyela elizinikele elisebenzisa isofthiwe yokulingisa ye-Zemax ne-CodeV ukuze libonise ukusebenza kwesistimu futhi libikezele ukuziphatha kokushisa/komshini ngaphansi kwezimo zokusebenza. Ilabhorethri yethu yokuxilonga izinto, ehlonyiswe nge-scanning electron microscopy (SEM) kanye ne-energy-dispersive X-ray spectroscopy (EDS), inikeza ukuhlaziywa kokuhluleka kwembangela yokuthuthukiswa kokuthembeka. Izinsizakalo zokuqinisekisa imvelo zifaka phakathi ukuhlolwa kokujikeleza kokushisa okukhulu (-196℃ kuya ku-800℃) kanye nokuvezwa kwe-salt spray yamahora angu-500 ngokwezindinganiso ze-MIL-STD-810G, okuqinisekisa ukuqina kwezingxenye ezimweni zokusebenza ezinzima.

Izinhlelo zokuqinisekisa ikhwalithi zisebenzisa ukulandeleka okugcwele kwezinto kusukela ku-crystal boule kuya kumkhiqizo oqediwe, kanti ingxenye ngayinye ihambisana nemibhalo ephelele yesitifiketi. Amandla okulinganisa asezingeni eliphezulu afaka phakathi i-interferometry ye-4D phase-shifting yokuqinisekisa ukunemba kobuso be-λ/50, i-interferometry yokukhanya okumhlophe efinyelela isinqumo sobukhali bobuso be-0.1nm, kanye nokuhlaziywa kwe-spectrophotometric okuhlanganisa ububanzi be-spectral be-190-3300nm ukuze kuchazwe ukudluliselwa/ukubonakaliswa.

Izinsizakalo ezingeziwe zibhekana nezidingo zesicelo ezikhethekile, kufaka phakathi izixazululo zokuhlanganiswa kwe-vacuum ezinemiphetho yensimbi ene-hermetic brazing yezinhlelo ze-vacuum eziphezulu kakhulu (UHV). Izinsizakalo zokulawula ukukhishwa kwe-electrostatic (ESD) zilungiselela ukumelana kobuso phakathi kuka-10⁶-10⁹Ω ukuvimbela ukuqongelela kweshaja ezinsimbini ezizwelayo. Zonke izingxenye zifakwa ekupakishweni kokugcina ezindaweni zokuhlanza ze-Class 100, ngokubalwa kwezinhlayiya ongazikhethela kanye nokupakishwa okubhakiwe nge-vacuum kwezidingo zokuhlanzeka kwe-semiconductor-grade.
