Magalasi Opepuka a High Purity SiC Optical Cubic 4H-semi 6SP Kukula Kopangidwa Mwamakonda Chithunzi Chodziwika

Kufotokozera Kwachidule:

Ma lens a SiC (ma lens a silicon carbide optical) ndi zinthu zowunikira bwino zopangidwa kuchokera ku silicon carbide (SiC) yoyera kwambiri, zomwe zimapereka mphamvu zapadera za physicochemical komanso magwiridwe antchito a kuwala. Ma lens a SiC omwe amadziwika ndi kutentha kwambiri (490 W/m·K), kutsika kwa kutentha (4.0×10⁻⁶/K), komanso kukhazikika kwachilengedwe, akhala chisankho chabwino kwambiri cha makina owonera omwe amagwira ntchito m'malo ovuta kwambiri. Ma lens awa amasonyeza magwiridwe antchito abwino kwambiri (kutumiza kosaphimbidwa >70%) kudutsa ma ultraviolet kupita ku ma wavelengths akutali a infrared (0.2-6 μm), zomwe zimapangitsa kuti akhale oyenera kwambiri makina amphamvu kwambiri a laser, space optics, ndi zithunzi za kuwala m'malo ovuta kwambiri a mafakitale.

Njira yopangira ma lens a SiC imaphatikizapo kupukuta bwino, kupukuta bwino kwambiri, ndi njira zapadera zopangira utoto kuti malo owoneka bwino akhale olondola pang'ono (kulimba kwa pamwamba <1 nm). Ma geometries apadera kuphatikiza malo a aspheric ndi freeform amatha kupangidwa kuti akwaniritse zofunikira pakupanga makina owoneka bwino kwambiri.

Mawonekedwe

Makhalidwe a Lens ya SiC Optical

1. Kupambana kwa Zinthu Zachilengedwe

Kusinthasintha Kwambiri kwa Malo: Imapirira kutentha >1500°C, dzimbiri la asidi/alkali, komanso mphamvu yamagetsi, yoyenera kugwiritsidwa ntchito m'malo osungira zinthu zakuthambo ndi zida za nyukiliya.

Mphamvu Yapadera ya Makina: Kulimba kwa pafupifupi diamondi (Mohs 9.5), mphamvu yopindika >400 MPa, ndi kukana kugwedezeka kopitirira galasi lachizolowezi.

Kukhazikika kwa Kutentha: Kuthamanga kwa kutentha ndi 100× kuposa silika yosakanikirana, yokhala ndi CTE 1/10 yokha ya galasi wamba, zomwe zimaonetsetsa kuti kutentha kuli kokhazikika pakagwa kutentha mwachangu.

2. Ubwino wa Magwiridwe Abwino a Maso

Kutumiza kwa ma spectral ambiri (0.2-6 μm); zokutira zapadera zimatha kupititsa patsogolo kutumiza kwa >95% m'mabande enaake (monga, 3-5 μm mid-IR).

Kutayika kochepa kwa kufalikira (<0.5%/cm), kutha kwa pamwamba kufika pa 10/5 scratch-dig standard, ndi kusalala kwa pamwamba pa λ/10@633 nm.

Chiwongolero chachikulu cha kuwonongeka komwe kumachitika chifukwa cha laser (LIDT) >15 J/cm² (1064 nm, 10 ns pulses), choyenera makina owunikira a laser amphamvu kwambiri.

3. Mphamvu Zopangira Machining Molondola

Imathandizira malo ovuta (aspheric, freeform) ndi kulondola kwa mawonekedwe <100 nm PV ndi centration <1 arcmin.

Wokhoza kupanga magalasi akuluakulu a SiC (m'mimba mwake > 500 mm) a ma telescope a zakuthambo ndi ma optic amlengalenga.

Kugwiritsa Ntchito Kwambiri kwa SiC Optical Lens

1. Malo Owonera ndi Chitetezo

Magalasi oonera kutali a satellite ndi ma telescope optics a mlengalenga, pogwiritsa ntchito mphamvu zopepuka za SiC (kuchuluka kwa 3.21 g/cm³) komanso kukana kuwala kwa dzuwa.

Mawindo owoneka bwino a missile seeking windows, omwe amatenthedwa ndi aerodynamic (>1000°C) panthawi youluka.

2. Makina a Laser Amphamvu Kwambiri

Magalasi olunjika a zida zodulira/kuwotcherera za laser zamafakitale, zomwe zimapangitsa kuti azigwiritsidwa ntchito nthawi yayitali ndi ma laser osalekeza a kW-class.

Zinthu zopangira mipiringidzo mu makina olumikizirana a inertial confinement (ICF), zomwe zimaonetsetsa kuti laser imafalikira molondola pogwiritsa ntchito mphamvu zambiri.

3. Kupanga Zinthu Molondola ndi Mosamalitsa

Ma substrates a magalasi a SiC a EUV lithography optics, okhala ndi kusintha kwa kutentha <1 nm pansi pa 10 kW/m² kutentha kwa flux.

Magalasi amagetsi a zida zowunikira za e-beam, pogwiritsa ntchito SiC's conductivity kuti azitha kuwongolera kutentha.

4. Kuyendera Mafakitale ndi Mphamvu

Magalasi a Endoscope a uvuni wotentha kwambiri (1500°C imagwira ntchito mosalekeza).

Zipangizo zowunikira za infrared za zida zolembera zitsime zamafuta, zomwe zimalimbana ndi kupsinjika kwa maenje olowera pansi (>100 MPa) ndi zophimba zowononga.

Ubwino Wapakati Wopikisana

1. Utsogoleri Wokwanira wa Magwiridwe Antchito
Magalasi a SiC amaposa zipangizo zamakono zowunikira (zosakanikirana ndi silica, ZnSe) pakukhala olimba pa kutentha/makina/mankhwala, ndi mphamvu zawo "zowongolera kwambiri + kukulitsa pang'ono" zomwe zimathetsa mavuto a kusintha kwa kutentha mu ma large optics.

2. Kugwiritsa Ntchito Ndalama Moyenera
Ngakhale kuti ndalama zoyambirira zimakhala zokwera, nthawi yayitali yogwiritsira ntchito ma lens a SiC (galasi wamba la 5-10 ×) komanso kugwiritsa ntchito popanda kukonza kumachepetsa kwambiri mtengo wonse wa umwini (TCO).

3. Ufulu Wopanga
Njira zolumikizidwa ndi reaction-bond kapena CVD zimathandiza kuti ma SiC optical structures opepuka (ma cores a uchi), akwaniritse ma ratios osayerekezeka a kuuma ndi kulemera.

Mphamvu za Utumiki wa XKH

1. Ntchito Zopangira Zapadera

Mayankho ochokera kumapeto mpaka kumapeto kuyambira pa kapangidwe ka kuwala (Zemax/Code V simulation) mpaka kufika komaliza, kuthandizira malo opanda mawonekedwe a parabolic aspheric/off-axis.

Zophimba zapadera: zotsutsana ndi kuwunikira (AR), kaboni wonga diamondi (LIDT>50 J/cm²), ITO yoyendetsa magetsi, ndi zina zotero.

2. Machitidwe Otsimikizira Ubwino

Zipangizo za Metrology kuphatikizapo ma interferometer a 4D ndi ma profiler oyera omwe amatsimikizira kulondola kwa pamwamba pa λ/20.

QC ya mulingo wazinthu: Kusanthula kwa XRD kwa mawonekedwe a kristalographic pa chilichonse chopanda kanthu cha SiC.

3. Ntchito Zowonjezera Mtengo

Kusanthula kwa ma thermo-structural coupling (ANSYS simulation) kuti mudziwiretu momwe zinthu zikuyendera.

Kapangidwe kowonjezera kapangidwe ka lenzi ya SiC yolumikizidwa.

Mapeto

Magalasi a SiC akukonzanso malire a magwiridwe antchito a makina owunikira olondola kwambiri kudzera muzinthu zawo zosayerekezeka. Mphamvu zathu zolumikizidwa molunjika mu kapangidwe ka zinthu za SiC, makina olondola, ndi mayeso zimapereka mayankho atsopano a kuwala kwa magawo opanga zinthu zakuthambo komanso apamwamba. Ndi kupita patsogolo kwa kukula kwa makristalo a SiC, chitukuko chamtsogolo chidzayang'ana kwambiri pa ma apertures akuluakulu (>1m) ndi ma geometries ovuta kwambiri (freeform arrays).

Monga wopanga zinthu zapamwamba kwambiri zowunikira, XKH imadziwika kwambiri ndi zipangizo zogwirira ntchito bwino monga safiro, silicon carbide (SiC), ndi ma silicon wafers, zomwe zimapereka mayankho kuyambira kumapeto mpaka kumapeto kuyambira kukonza zinthu zopangira mpaka kumaliza bwino. Ukadaulo wathu umaphatikizapo:

1. Kupanga Mwamakonda: Kupanga mwaluso kwambiri kwa ma geometries ovuta (aspheric, freeform) okhala ndi tolerances mpaka ± 0.001mm

2. Kusinthasintha kwa Zinthu: Kukonza safiro (mawindo a UV-IR), SiC (ma optic amphamvu kwambiri), ndi silicon (IR/micro-optics)

3. Ntchito Zowonjezera Mtengo:

Zophimba zoletsa kuwunikira/zolimba (UV-FIR)

Chitsimikizo cha khalidwe chothandizidwa ndi Metrology (λ/20 flatness)

Kusonkhanitsa zipinda zotsukira kuti zigwiritsidwe ntchito mosamala chifukwa cha kuipitsidwa

Potumikira mafakitale a ndege, semiconductor, ndi laser, timaphatikiza ukatswiri wa sayansi ya zinthu ndi kupanga kwapamwamba kuti tipereke kuwala komwe kumapirira malo ovuta kwambiri komanso kukonza magwiridwe antchito a kuwala.
