Mawonekedwe Opangidwa ndi Sapphire Optical Windows High Purity Transmittance ≥90%

Kufotokozera Kwachidule:

Mawindo a Sapphire optical ndi zida zapadera zowunikira zopangidwa kuchokera ku single-crystal aluminum oxide (Al₂O₃), yotchuka chifukwa cha magwiridwe antchito awo apadera a kuwala, mphamvu ya makina, komanso kukhazikika kwa mankhwala. Popeza ndi kristalo wolimba kwambiri wa oxide (kuuma kwa Mohs 9), mawindo a Sapphire amawonetsa kufalikira kwabwino kwambiri (~83-85% osaphimbidwa) kudutsa ultraviolet (200nm) kupita ku mid-infrared (5.5μm) spectra, zomwe zimapangitsa kuti akhale abwino kwambiri pakugwiritsa ntchito zinthu zovuta zomwe zimafuna kuwonekera bwino komanso kulimba.

Kupanga kumaphatikizapo njira zofunika kwambiri kuphatikizapo kukula kwa ma kristalo, kudula kolondola, kupukuta kwa nanoscale, ndi utoto wapadera. Njira zamakono zokulira (monga njira za HEM kapena KY) zimapereka maboules apamwamba okhala ndi chilema chochepa (<10⁴/cm²). Kapangidwe kapadera ka ma kristalo a hexagonal kamalola mawonekedwe a anisotropic, okhala ndi mawonekedwe okonzedwa bwino (C-axis, A-axis, kapena R-plane cuts) omwe amasintha magwiridwe antchito a kuwala kuti agwiritsidwe ntchito mwanjira inayake.

Makhalidwe Ofunika

1. Kusinthasintha Kwambiri kwa Malo Ozungulira
Mawindo a kuwala a safiro amasonyeza bwino kwambiri ndi kutentha kwa 2053°C, kusunga umphumphu wa kapangidwe kake m'malo ogwirira ntchito a 1000°C mosalekeza. Kukhazikika kwa kutentha kumeneku kumathandizidwa ndi kuchuluka kochepa kwambiri kwa kutentha (CTE) kwa 5.3×10⁻⁶/K motsatira C-axis, kopambana kwambiri kuposa magalasi wamba owonera. Mwa mankhwala, mawindo a kuwala a safiro amasonyeza kusakhala bwino kwa kuwala, kukana ma asidi onse amphamvu (kupatula HF) ndi alkalis, zomwe zimapangitsa kuti akhale abwino kwambiri pazida zopangira mankhwala ndi ntchito zam'madzi. Mwa makina, mawindo awa ali ndi mphamvu yosinthasintha yoposa 1000MPa (yamphamvu nthawi 5-8 kuposa galasi wamba) yokhala ndi kukana kwakukulu kwa kukhudza.

2. Ubwino wa Magwiridwe a Ntchito
Mawindo a kuwala a safiro amapereka kufalikira kwa >80% pamitundu yosiyanasiyana (200-5500nm pa makulidwe a 2mm). Kudzera mu mawonekedwe abwino a kristalo (monga C-axis perpendicular to light path), zotsatira za birefringence zimachepetsedwa bwino. Ubwino wa pamwamba umakwaniritsa zofunikira zolimba za kuwala ndi λ/10 flatness pa 633nm ndi roughness pamwamba <0.5nm RMS.

3.Kupanga Zinthu Mwapamwamba
Mawindo athu a safiro amathandizira kukonza kwakukulu (>300mm m'mimba mwake) ndi ma geometri ovuta kuphatikiza mawonekedwe a aspheric ndi masitepe. Ukadaulo wapadera wotsekera m'mphepete umakwaniritsa kuchuluka kwa kutayikira <1×10⁻⁹Pa·m³/s pakugwiritsa ntchito vacuum. Ndi zokutira za kaboni ngati diamondi (DLC), malire owonongeka omwe amayambitsidwa ndi laser (LIDT) amafika pa 15J/cm² (1064nm, 10ns pulses).

Mapulogalamu Oyambirira

1. Chitetezo ndi Ndege
Mawindo owoneka ngati safiro amagwira ntchito ngati ma dome a zida zankhondo, omwe amatha kupirira kutentha kwambiri (>1000°C) panthawi youluka. Mitundu yosiyanasiyana ya zida zamlengalenga imatsimikizira moyo wautumiki wanthawi zonse wazaka zoposa 15 mu ntchito zamlengalenga.

2. Zipangizo Zamakampani
Pakupanga ma semiconductor, mawindo a safiro owoneka bwino amagwira ntchito ngati malo owonera omwe sagonjetsedwa ndi plasma m'zipinda za etch ndi CVD. Ma endoscope otentha kwambiri amagwiritsa ntchito mawindo awa kuti azitha kujambula bwino m'malo otentha a 1500°C.

3. Zida Zasayansi
Mawindo owoneka bwino a safiro (<5ppm desprits) amachepetsa kuyamwa kwa X-ray mu synchrotron beamlines. Kusalumikizana kwawo kochepa kumasunga kukhulupirika kwa femtosecond pulse mu machitidwe a laser othamanga kwambiri.

4. Zipangizo Zamalonda
Zipangizo zozama pansi pa nyanja zimakhala ndi mawindo a safiro owoneka bwino omwe ali ndi kuya kwa mamita 6000 (>60MPa). Makamera a mafoni amaphatikiza mawindo awa ngati zophimba zoteteza, pogwiritsa ntchito mphamvu ya Mohs 9 yolimba kuti ikhale yolimba.

Mawindo a kuwala a safiro akupitilizabe kukulitsa ntchito zawo kudzera mu kupita patsogolo kwa kukonza kwakukulu, ma geometri ovuta, komanso magwiridwe antchito abwino, zomwe zimapangitsa kuti malo awo akhale ofunikira kwambiri m'mafakitale apamwamba.

Ntchito za XKH

Pulogalamu yolumikizirana ya XKH imaphatikiza ukatswiri wamakono wopanga zinthu ndi chithandizo chaukadaulo champhamvu kuti ipereke mayankho a mawindo a safiro owoneka bwino. Gawo lopanga zinthu mwamakonda limapereka njira zojambulira zojambula ndi luso lonse losintha mafayilo a 2D/3D, lothandizidwa ndi ntchito zowongolera za Design for Manufacturing (DFM) zomwe zimachepetsa zoopsa ndi ndalama zopangira. Timasunga luso lopanga zinthu mwachangu kwambiri, timapereka zitsanzo zogwira ntchito za Φ100mm mkati mwa masiku 5 ogwira ntchito kuti tifulumizitse kupanga zinthu. Njira zamakono zogwirira ntchito zimaphatikizapo zokutira zowongolera zolondola zokhala ndi kukana kwa pepala komwe kumatha kusinthidwa kuchokera ku 10-1000Ω/□ pakugwiritsa ntchito zotchingira za EMI, pamodzi ndi mafilimu apadera oletsa chifunga omwe amasunga kumveka bwino kwa kuwala m'malo omwe ali ndi chinyezi chambiri.

Malo othandizira aukadaulo ali ndi gulu lodzipereka la mainjiniya lomwe limagwiritsa ntchito pulogalamu ya Zemax ndi CodeV optical simulation kuti liwonetse momwe makina amagwirira ntchito ndikulosera momwe kutentha/makina amagwirira ntchito. Laboratory yathu yowunikira zinthu, yokhala ndi scanning electron microscopy (SEM) ndi energy-dispersive X-ray spectroscopy (EDS), imapereka kusanthula kwa kulephera kwa mizu kuti iwonjezere kudalirika. Ntchito zotsimikizira zachilengedwe zimaphatikizapo mayeso othamanga kwambiri (-196℃ mpaka 800℃) ndi kuwonetsedwa kwa mchere kwa maola 500 motsatira miyezo ya MIL-STD-810G, kuonetsetsa kuti zinthuzo zimakhala zolimba m'mikhalidwe yovuta yogwirira ntchito.

Machitidwe otsimikizira khalidwe amapereka njira yonse yodziwira zinthu kuyambira pa bolodi la kristalo kupita ku chinthu chomalizidwa, ndipo gawo lililonse limaphatikizidwa ndi zikalata zonse zovomerezeka. Mphamvu zamakono zoyezera zinthu zimaphatikizapo 4D phase-shifting interferometry kuti zitsimikizire kulondola kwa pamwamba pa λ/50, white-light interferometry yomwe imakwaniritsa kukhwima kwa pamwamba pa 0.1nm, ndi kusanthula kwa spectrophotometric komwe kumaphimba 190-3300nm spectral range kuti ziwonetsedwe/kuwunikira.

Ntchito zowonjezera mtengo zimayang'anira zofunikira zapadera zogwiritsira ntchito, kuphatikizapo njira zophatikizira vacuum zomwe zili ndi m'mphepete mwachitsulo zokhala ndi chotchingira chopanda madzi cha makina a vacuum okwera kwambiri (UHV). Ntchito zowongolera kutulutsa kwa electrostatic (ESD) zimasintha kukana kwa pamwamba pakati pa 10⁶-10⁹Ω kuti zipewe kusonkhana kwa mphamvu mu zida zomvera. Zigawo zonse zimayikidwa mu phukusi lomaliza m'malo oyeretsera a Class 100, ndi kuwerengera tinthu tomwe timasankha komanso kuyika mu vacuum kuti zigwirizane ndi zofunikira za ukhondo wa semiconductor.
