Ubuziranenge Bwinshi SiC Optical Lens Cubic 4H-semi 6SP Ingano Yashushanyijeho Ishusho

Ibisobanuro bigufi:

Lens ya SiC (silicon carbide optique lens) nibintu byiza bya optique byahimbwe na karbide ya silicon nziza cyane (SiC), itanga ibintu bidasanzwe bya fiziki na chimique nibikorwa byiza. Kurangwa nubushyuhe bwumuriro wa ultrahigh (490 W / m · K), coefficient nkeya yo kwagura ubushyuhe (4.0 × 10⁻⁶ / K), hamwe n’ibidukikije bidasanzwe, ibidukikije bya SiC byahindutse uburyo bwiza bwa sisitemu optique ikora mubihe bikabije. Izi lens zigaragaza imikorere ihebuje yo kohereza (transmitance idahwitse> 70%) hejuru ya ultraviolet kugera kumurambararo wa kure cyane (0.2-6 μ m), bigatuma bikwiranye cyane na sisitemu ya lazeri ifite ingufu nyinshi, optique yo mu kirere, hamwe n'amashusho ya optique mubidukikije bikabije.

Igikorwa cyo gukora lens ya SiC gikubiyemo gusya neza, gusya cyane-gukonjesha, hamwe nubuvuzi bwihariye bwo gutwikira kugirango ugere kuri optique hamwe na nanoscale neza (uburinganire bwubutaka <1 nm). Gometrike yihariye harimo na asifike nubusa byubusa birashobora guhimbwa kugirango byuzuze ibisabwa bya sisitemu yo mu rwego rwo hejuru.

Ibiranga

Ibiranga SiC Optical Lens

Ibidukikije bikabije Kurwanya imihindagurikire y'ikirere: Ihangane n'ubushyuhe> 1500 ° C, aside ikomeye / ruswa ya alkali, hamwe n'imirasire y'ingufu nyinshi, byiza mu byogajuru n'ibikoresho bya kirimbuzi.

Imbaraga zidasanzwe za mashini: Gukomera hafi ya diyama (Mohs 9.5), imbaraga zidasanzwe> 400 MPa, hamwe no kurwanya ingaruka zirenze kure ibirahuri bisanzwe.

Ubushyuhe bwumuriro: Ubushyuhe bwumuriro 100 × hejuru ya silika yahujwe, hamwe na CTE 1/10 gusa cyikirahure gisanzwe, bigatuma umutekano uhagarara mumagare yihuta.

2. Ibyiza byo gukora neza

Ikwirakwizwa ryagutse (0.2-6 μ m); impuzu zihariye zishobora guhindura uburyo bwo kohereza kuri> 95% mumatsinda yihariye (urugero, 3-5 mm hagati ya IR).

Igihombo gito cyo gutatanya (<0.5% / cm), hejuru irangiza kugeza 10/5 igipimo cyo gucukumbura, hamwe nuburinganire bwubutaka λ / 10 @ 633 nm.

Ibyangiritse byatewe na laser (LIDT)> 15 J / cm² (1064 nm, 10 ns pulses), bikwiranye na sisitemu yo kwibanda cyane kuri laser.

3. Ubushobozi bwo Gukora neza

Shyigikira ubuso bugoye (aspheric, freeform) hamwe nukuri neza <100 nm PV hamwe na centration <1 arcmin.

Irashobora guhimba lens nini ya SiC (diameter> 500 mm) kuri telesikope yubumenyi bwikirere hamwe na optique yumwanya.

Porogaramu Yibanze ya SiC Optical Lens

1. Umwanya wa Optics & Defence

Satelite ya kure yunvikana hamwe na telesikopi yo mu kirere, ikoresha ibikoresho bya SiC byoroheje (ubucucike 3.21 g / cm³) hamwe no kurwanya imirasire.

Ushakisha misile optique ya windows, yihanganira ubushyuhe bwindege (> 1000 ° C) mugihe cyo kuguruka hypersonic.

2. Sisitemu Yimbaraga Zinshi

Kwibanda kumurongo wibikoresho byo gukata / gusudira ibikoresho, bikomeza kumara igihe kinini kuri kW-icyiciro gikomeza.

Ibikoresho byerekana ibiti muri sisitemu yo gufunga (ICF), bikwirakwiza ingufu za laser nyinshi.

3. Semiconductor & Gukora neza

Indorerwamo ya SiC isobanura EUV lithographie optique, hamwe nubushyuhe bwumuriro <1 nm munsi ya 10 kW / m² ubushyuhe.

Ibikoresho bya electromagnetic kubikoresho byo kugenzura e-beam, ukoresheje ubushobozi bwa SiC kugirango ugenzure ubushyuhe bukabije.

4. Kugenzura Inganda & Ingufu

Endoscope yerekana itanura ryubushyuhe bwo hejuru (1500 ° C ikomeza gukora).

Ibikoresho bya infragre optique kubikoresho byo gutema amavuta neza, birwanya umuvuduko wo hasi (> 100 MPa) nibitangazamakuru byangirika.

Ibyiza byo Kurushanwa

1. Ubuyobozi Bwuzuye Bwuzuye
Lens ya SiC irenze ibikoresho bisanzwe bya optique (silika yahujwe, ZnSe) mumashanyarazi / ubukanishi / imiti ihamye, hamwe nubushobozi bwabo "bwo hejuru cyane + kwaguka kwinshi" bikemura ibibazo byo guhindura ubushyuhe muri optique nini.

2. Ikiguzi cyubuzima bwiza
Mugihe ibiciro byambere biri hejuru, SiC lens yongerewe igihe cya serivisi (5-10 glass ikirahuri gisanzwe) hamwe nigikorwa cyo kubungabunga ibidukikije bigabanya cyane igiciro cya nyirubwite (TCO).

3. Gutegura Ubwisanzure
Ibikorwa bifitanye isano cyangwa CVD ituma ibyubaka bya SiC byoroheje byubaka (ibimamara by ubuki), bigera ku gipimo ntagereranywa-ku bipimo.

Ubushobozi bwa XKH

1. Serivise zo gukora ibicuruzwa

Ibisubizo byanyuma-byanyuma biva muburyo bwa optique (Zemax / Code V simulation) kugeza kubitanga byanyuma, bishyigikira aspheric / off-axis parabolike yubusa.

Impuzu zihariye: anti-reaction (AR), karubone isa na diyama (LIDT> 50 J / cm²), ITO ikora, nibindi.

2. Sisitemu Yubwishingizi Bwiza

Ibikoresho bya Metrology harimo 4D interterometero na cyera-urumuri rwerekana neza λ / 20 hejuru yukuri.

Urwego-Ibikoresho QC: XRD kristu yerekana icyerekezo kuri buri SiC irimo ubusa.

3. Serivisi zongerewe agaciro

Isesengura rya Thermo-structure (ANSYS simulation) yo guhanura imikorere.

Igishushanyo mbonera cya SiC cyerekana imiterere yo gutezimbere.

Umwanzuro

Lens ya SiC irimo gusobanura imipaka yimikorere ya sisitemu yo hejuru ya optique ikoresheje ibintu bitagereranywa. Ubushobozi bwacu bwahujwe muburyo bwa synthesis ya SiC, gutunganya neza, no kugerageza bitanga ibisubizo byimpinduramatwara kubirere byindege hamwe ninganda zikora inganda. Hamwe niterambere muri SiC kristu yo gukura, iterambere rizaza rizibanda kuri aperture nini (> 1m) hamwe na geometrike igoye cyane (freeform array).

Nkumushinga wambere wambere mubikoresho bigezweho bya optique, XKH kabuhariwe mubikoresho bikora cyane birimo safiro, karbide ya silicon (SiC), na wafer ya silicon, itanga ibisubizo byanyuma kugeza kumpera kuva gutunganya ibikoresho fatizo kugeza kurangiza neza. Ubuhanga bwacu bugenda:

1.Ibihimbano byabigenewe: Gutunganya neza geometrike igoye (aspheric, freeform) hamwe no kwihanganira ± 0.001mm

2. Guhindura ibikoresho: Gutunganya safiro (Windows ya UV-IR), SiC (optique ifite ingufu nyinshi), na silicon (IR / micro-optique)

3. Serivisi zongerewe agaciro:

Kurwanya-kwerekana / kuramba (UV-FIR)

Metrology-ishyigikiwe nubwiza bufite ireme (λ / 20 uburinganire)

Iteraniro ryisuku kubikorwa byanduye

Gukorera mu kirere, mu gice cya kabiri, no mu nganda za lazeri, duhuza ubumenyi bwa siyansi y’ibikoresho n’inganda zateye imbere kugira ngo dutange optique ihanganira ibidukikije bikabije mu gihe tunoza imikorere ya optique.
