High Purity SiC Optical Lens Cubic 4H-semi 6SP Saizi Yakagadzirirwa

Tsananguro pfupi:

Malenzi eSiC (silicon carbide optical lenses) zvinhu zvakagadzirwa nesilicon carbide (SiC) ine hunhu hwakanaka hwefizikisi uye mashandiro ekuona. Malenzi eSiC anoratidzwa nekupisa kwakanyanya (490 W/m·K), kuwedzera kwekupisa kwakaderera (4.0×10⁻⁶/K), uye kugadzikana kwezvakatipoteredza, ave sarudzo yakanakisisa yemasisitimu ekuona anoshanda mumamiriro ezvinhu akaipisisa. Malenzi aya anoratidza mashandiro akanaka ekutumira (kutumirwa kusina kuvharwa >70%) kuburikidza neultraviolet kuenda kumarefu einfrared wavelengths (0.2-6 μm), zvichiita kuti anyatsokodzera masisitimu elaser ane simba guru, space optics, uye optical imaging munzvimbo dzakaoma dzemaindasitiri.

Maitiro ekugadzira malenzi eSiC anosanganisira kukuya nemazvo, kupukuta nemazvo zvakanyanya, uye kurapwa kwakanyatsogadzirwa kuti pave nepamusoro pemaziso ne nanoscale accuracy (surface roughness <1 nm). Ma geometries akagadzirwa anosanganisira aspheric uye freeform surfaces anogona kugadzirwa kuti asvike pazvinodiwa zvemagadzirirwo ema optical systems ane magadzirirwo akanyanya.

Hunhu hweSiC Optical Lens

1. Kubudirira Kwezvinhu

Kuchinjika Kwakanyanya Kwenzvimbo: Inotsungirira tembiricha >1500°C, ngura yakasimba yeasidhi/alkali, uye mwaranzi ine simba rakawanda, yakakodzera nzvimbo dzemuchadenga nedzenyukireya.

Simba Rinoshamisa reMichina: Kuomarara kwedhaimani (Mohs 9.5), simba rekuchinjika >400 MPa, uye kuramba kusimba kwemuchina kupfuura girazi remagetsi remazuva ano.

Kugadzikana kweThermal: Kutenderera kweThermal kwakakwirira 100× kupfuura fused silica, neCTE 1/10 chete yegirazi rakajairika, zvichiita kuti pave nekugadzikana kana kupisa kuchikwira nekukurumidza.

2. Mabhenefiti Ekushanda Kwemaziso

Kutapurirana kwe broad spectral (0.2-6 μm); machira akagadzirwa anogona kuvandudza kutapurirana kusvika >95% mumabhendi chaiwo (semuenzaniso, 3-5 μm mid-IR).

Kurasikirwa nekupararira kwakaderera (<0.5%/cm), kupedzisa pamusoro kusvika pa10/5 scratch-dig standard, uye surface flatness λ/10@633 nm.

High laser-induced damage threshold (LIDT) >15 J/cm² (1064 nm, 10 ns pulses), yakakodzera masisitimu e laser ane simba guru.

3. Kugona Kugadzira Machining Nemazvo

Inotsigira nzvimbo dzakaoma (dzakapfava, dzisina chimiro) nekunyatsorongeka kwechimiro <100 nm PV uye kudzika <1 arcmin.

Inokwanisa kugadzira malenzi makuru eSiC (dhayamita >500 mm) eteresikopu dzemuchadenga nedzemuchadenga.

Mashandisirwo Akakosha eSiC Optical Lens

1. Space Optics & Dziviriro

Magirazi ekuona ari kure esatellite uye magirazi ekuona ari muchadenga, achishandisa hunhu hweSiC hwakareruka (huremu hwe3.21 g/cm³) uye kudzivirira mwaranzi.

Mahwindo echiedza anotsvaga zvombo, anogara achidziya (>1000°C) panguva yekubhururuka kwemhepo.

2. Masisitimu eLaser Ane Simba Rakawanda

Magirazi ekutarisa emidziyo yekucheka/kushongedza nelaser yeindasitiri, achichengetedza nguva refu achishandiswa malaser anoenderera mberi ekirasi yekW.

Zvinhu zvinoumba danda mumasisitimu ekubatanidza inertial confinement (ICF), zvichiita kuti zvive nechokwadi chekuti laser inotumirwa nesimba rakawanda.

3. Kugadzira Semiconductor & Precision

Zvishandiso zvegirazi zveSiC zveEUV lithography optics, zvine thermal deformation <1 nm pasi pe10 kW/m² heat flux.

Magirazi emagetsi ekushandisa maturusi ekuongorora e-beam, achishandisa SiC's conductivity yekudzora tembiricha inoshanda.

4. Kuongorora Maindasitiri & Simba

Magirazi eEndoscope ezvitofu zvinopisa zvakanyanya (1500°C inoshanda nguva dzose).

Zvishandiso zve infrared optical zvekushandisa pakuchekerera mafuta, zvinodzivirira kumanikidzwa kwemugodhi (>100 MPa) uye zvinoparadza.

Mabhenefiti Emakwikwi Akakosha

1. Hutungamiriri Hwakakwana hweKushanda
Magirazi eSiC anopfuura zvinhu zvechinyakare zve optical (fused silica, ZnSe) mukupisa/kugadzika kwemakemikari, ane "high conductivity + low expansion" maitiro avo ekugadzirisa matambudziko ekupisa muma optics makuru.

2. Kushanda Nesimba Kwemari Yehupenyu Hwese
Kunyange zvazvo mitengo yekutanga yakakwira, hupenyu hwekushanda kweSiC lenses (5-10× girazi remazuva ose) uye kushanda pasina kugadzirisa zvinoderedza zvakanyanya mutengo wekuva muridzi (TCO).

3. Rusununguko rwekugadzira
Maitiro ekubatanidza ma "reaction-bonded" kana kuti CVD anogonesa ma "SiC optical structures" akareruka (honeycomb cores), zvichiita kuti pave nekusimba kusingaenzaniswi pakati pehuremu ne "hardness-to-weight ratios".

Kugona Kwebasa reXKH

1. Mabasa Ekugadzira Zvinhu Zvakagadzirwa Nevanhu

Mhinduro dzinobva pakugadzira optical (Zemax/Code V simulation) kusvika pakutumira kwekupedzisira, zvichitsigira aspheric/off-axis parabolic freeform surfaces.

Mapfekero akasarudzika: anti-reflection (AR), dhaimani-yakaita sekabhoni (LIDT>50 J/cm²), conductive ITO, nezvimwewo.

2. Masisitimu Ekusimbisa Hunhu

Midziyo yeMetrology inosanganisira 4D interferometers uye maprofayiri echiedza chena zvinoita kuti λ/20 ive yakarongeka pamusoro.

QC yedanho rezvinhu: Kuongorora kwekutarisa kweXRD kweSiC yega yega isina chinhu.

3. Mabasa Akawedzerwa Kukosha

Kuongorora kwekubatanidza kweThermo-structural (ANSYS simulation) yekufanotaura mashandiro.

Dhizaini yekugadzirisa chimiro chekuisa lenzi yeSiC yakabatanidzwa.

Mhedziso

Magirazi eSiC ari kutsanangura patsva miganho yekushanda kwemasisitimu e optical akanyatsogadzirwa kuburikidza nehunhu hwawo husina muganho. Hunhu hwedu hwakabatanidzwa mukugadzira zvinhu zveSiC, kugadzira machine chaiyo, uye kuyedza zvinopa mhinduro dze optical dzinochinja-chinja muzvikamu zvekugadzira zvemuchadenga nepamusoro. Nekufambira mberi mukukura kweSiC crystal, kufambira mberi mune ramangwana kuchatarisa pamipata yakakura (>1m) uye ma geometries akaomarara epamusoro (freeform arrays).

Semugadziri anotungamira wezvinhu zvepamusoro zve optical, XKH inonyanya kugadzira zvinhu zvinoshanda zvakanyanya zvinosanganisira safira, silicon carbide (SiC), uye silicon wafers, zvichipa mhinduro dzakasiyana-siyana kubva pakugadzirisa zvinhu kusvika pakupedzisa nemazvo. Hunyanzvi hwedu hunosanganisira:

1. Kugadzira Zvakagadzirwa Nemaoko: Kugadzira nemazvo ma geometries akaomarara (aspheric, freeform) ane kushivirira kusvika ±0.001mm

2. Kuchinja-chinja kwezvinhu: Kugadzira sapphire (mahwindo eUV-IR), SiC (magirazi ane simba guru), uye silicon (IR/micro-optics)

3. Mabasa Akawedzerwa Kukosha:

Mapendi anodzivirira kupenya/anogara kwenguva refu (UV-FIR)

Kuvimbiswa kwemhando yepamusoro kunotsigirwa neMetrology (λ/20 flatness)

Kuungana kwenzvimbo yekugezera yekushandiswa kunokonzerwa nekusvibiswa

Tichishandira maindasitiri emuchadenga, semiconductor, uye laser, tinobatanidza hunyanzvi hwesainzi yezvinhu nekugadzira zvinhu zvepamusoro kuti tipe optics dzinotsungirira mamiriro ezvinhu akaomarara uku tichivandudza mashandiro e optical.
