HPSI SiC Wafer ≥90% Transmittance Optical Grade yeAI/AR Glasses
Nhanganyaya Yekutanga: Basa reHPSI SiC Wafers muAI/AR Glasses
Magirazi eSilicon Carbide eHPSI (High-Purity Semi-Insulating) mawafers akasarudzika ane resistivity yakakwira (>10⁹ Ω·cm) uye defect density yakaderera zvikuru. Mumagirazi eAI/AR, anonyanya kushanda sezvinhu zvemukati zve diffractive optical waveguide lenses, achigadzirisa matambudziko ane chekuita nezvinhu zvechinyakare zve optical maererano nechimiro chakatetepa uye chakareruka, kupisa kunopera, uye mashandiro e optical. Semuenzaniso, magirazi eAR anoshandisa magirazi eSiC waveguide anogona kuwana ultra-wide field of view (FOV) ye70°–80°, ukuwo achideredza ukobvu hwe single lens layer kusvika 0.55mm chete uye huremu kusvika 2.7g chete, zvichiwedzera zvakanyanya kunyaradzwa kwekupfeka uye kunyura mumaziso.
Hunhu Hukuru: Maitiro eSiC Material Anosimudzira Dhizaini yeAI/AR Glasses
High Refractive Index uye Optical Performance Optimization
- SiC's refractive index (2.6–2.7) yakakwira ne50% kupfuura yegirazi rekare (1.8–2.0). Izvi zvinobvumira magadzirirwo ewaveguide akatetepa uye anoshanda zviri nani, zvichiwedzera zvakanyanya FOV. Iyo high refractive index inobatsirawo kudzvinyirira "rainbow effect" inowanikwa mumawaveguide ediffractive, zvichivandudza kuchena kwemufananidzo.
Kugona Kutarisira Kupisa Kunoshamisa
- Nekufambiswa kwemhepo kwekupisa kwakakwira kusvika ku490 W/m·K (pedyo nemhangura), SiC inogona kukurumidza kubvisa kupisa kunogadzirwa neMicro-LED display modules. Izvi zvinodzivirira kudzikira kwekushanda kana kukwegura kwemudziyo nekuda kwekupisa kwakanyanya, zvichiita kuti bhatiri rigare kwenguva refu uye kugadzikana kwakanyanya.
Simba reMichina uye Kugara kwenguva refu
- SiC ine kuomarara kweMohs kwe9.5 (kwechipiri kubva kudhaimani), ichidzivirira kukwenya kwakanyanya, zvichiita kuti ive yakakodzera magirazi anoshandiswa nevanhu vakawanda. Kukwenya kwayo pamusoro kunogona kudzorwa kusvika kuRa < 0.5 nm, zvichiita kuti chiedza chisarasike zvakanyanya uye chienderane zvakanyanya mumawaveguides.
Kuenderana Kwemidziyo Yemagetsi
- Kudzivirira kweHPSI SiC (>10⁹ Ω·cm) kunobatsira kudzivirira kukanganiswa kwemasaini. Inogonawo kushanda sechishandiso chemagetsi chinoshanda zvakanaka, ichivandudza mamodule ekutonga magetsi mumagirazi eAR.
Mirayiridzo Yekutanga Yekushandisa
Zvikamu zveOptical zveAI/AR Glasses
- MaLenses eDiffractive Waveguide: MaSiC substrates anoshandiswa kugadzira mawaveguide eoptical akatetepa zvikuru anotsigira FOV yakakura uye kubvisa murarabungu.
- Mapuratifomu eMahwindo nePrisms: Kuburikidza nekucheka nekupukuta kwakagadzirwa, SiC inogona kugadzirwa kuita mahwindo anodzivirira kana maprisms ekuona egirazi reAR, zvichiwedzera kufambiswa kwechiedza uye kuramba kupfeka.
Kuwedzerwa Kwemapurogiramu Mune Mimwe Minda
- Magetsi Emagetsi: Anoshandiswa muzviitiko zvine simba guru, zvakaita sema inverter emotokari itsva ane simba uye ma industrial motor controls.
- Quantum Optics: Inoshanda senzvimbo yekuisa mavara, inoshandiswa muzvikamu zvekutaurirana kwequantum uye zvishandiso zvekunzwa.

Mabasa eXKH: Kugona Kugadzira Kwakabatana uye Kugadzirisa
Kambani yeXKH ine hunyanzvi hwekubatanidza zvinhu kubva pazvinhu zvakagadzirwa kusvika kuma wafers apera, zvichifukidza kukura kwese kweSiC substrate, kucheka, kupolisha, uye kugadzirisa zvinhu zvakagadzirwa. Zvakanakira zvikuru zvebasa zvinosanganisira:
- Kusiyana-siyana kwezvinhu:Tinogona kupa mhando dzakasiyana dzewafer dzakadai se4H-N type, 4H-HPSI type, 4H/6H-P type, uye 3C-N type. Kuramba, ukobvu, uye kurongeka zvinogona kugadziriswa zvichienderana nezvinodiwa.
- .Kugadzirisa Saizi Inochinjika:Tinotsigira kugadzirwa kwewafer kubva pa 2-inch kusvika 12-inch dhayamita, uye tinokwanisawo kugadzirisa zvivakwa zvakakosha zvakaita sezvidimbu zvesikweya (semuenzaniso, 5x5mm, 10x10mm) uye ma prism asina kurongeka.
- Kudzora Kwakarurama Kwegiredhi Remaziso:Kuchinja kweTTV (Wafer Total Thickness Variation) kunogona kuchengetwa pa <1μm, uye kuomarara kwenzvimbo paRa < 0.3 nm, zvichizadzisa zvinodiwa zve nano-level flatness zvemidziyo yewaveguide.
- Mhinduro yeMusika Inokurumidza:Muenzaniso webhizinesi wakabatanidzwa unovimbisa shanduko inoshanda kubva pakutsvaga nekuvandudza zvinhu kuenda pakugadzirwa kwezvinhu zvakawanda, zvichitsigira zvese kubva pakusimbiswa kwezvinhu zvidiki kusvika pakutumirwa kwezvinhu zvakawanda (nguva yekutungamirwa inowanzova mazuva gumi nemashanu kusvika makumi mana).
Mibvunzo Inowanzo bvunzwa nezve HPSI SiC Wafer
Mubvunzo 1: Sei HPSI SiC ichionekwa sechinhu chakanakira magirazi eAR waveguide?
A1: Chiratidzo chayo chepamusoro che refractive index (2.6–2.7) chinoita kuti magadzirirwo emafungu matete uye anoshanda zvakanaka anotsigira nzvimbo yakakura yekuona (semuenzaniso, 70°–80°) ukuwo achibvisa "rainbow effect".
Mubvunzo wechipiri: HPSI SiC inovandudza sei kutarisirwa kwekupisa mumagirazi eAI/AR?
