I-Silicon Carbide Prism / Isibuko Se-Infrared Optics Aerospace-Grade

Incazelo emfushane:

Isibuko esiyisicaba se-silicon carbide (SiC) siyingxenye ye-optical esezingeni eliphezulu eyenziwe nge-ceramic ye-SiC ethuthukisiwe. Sinesilinganiso esiyingqayizivele sokuqina-kuya-esisindoni, ukusebenza okuphezulu kwe-infrared, kanye nokuqina kwemvelo okuvelele, kuyisinqumo esifanele sezinhlelo ze-optical ezidinga kakhulu. Uma kuqhathaniswa nezinto zendabuko ezifana ne-fused silica, i-germanium, ne-zinc selenide, izibuko ze-SiC azigcini nje ngokugqama phakathi kwe-infrared spectrum kodwa futhi ziletha amandla alula, aphezulu omshini, kanye nokuzinza kwesikhathi eside ngaphansi kwezimo zokusebenza ezinzima.

Umdwebo Oningiliziwe

Ukubuka konke

Lesi sibuko sisetshenziswa kabanzi emithwalweni yezindiza, ezinhlelweni ze-laser, ekuthathweni kwezithombe ze-infrared, kanye nasemetrology enembile kakhulu.

Izici Eziyinhloko

Ukulungiswa kwesakhiwo okulula: Umklamo othuthukisiwe onezakhiwo zezinyosi kanye ne-topology unciphisa isisindo ngaphandle kokulahlekelwa amandla.
Ilula kakhulu: Ilula kakhulu kunezingqimba zesibuko ezivamile, ezibalulekile kumapulatifomu ezindiza kanye neselula.
Ukuqina okuphezulu: Igcina ukunemba komfanekiso womphezulu ngisho noma inezimbobo ezinkulu nezincane.
Ukwanda okuphansi kokushisa: Iqinisekisa ukusebenza kokukhanya kuzo zonke izinguquko zokushisa okusheshayo noma okweqile.
Ukumelana nokuklwebheka nokuguguleka: Ukuqina okufana nedayimane, ukumelana nokuguguleka kwemvelo.
Ukuqedwa kobuso obunembile kakhulu: Ukuthamba ≤ 1 μm, ikhwalithi yobuso ifanelekela izithombe ezidingakalayo kanye nezinhlelo zokusebenza ze-laser.

Izinzuzo Zokusebenza

Ukuqina okuphezulu kanye nobukhulu: I-modulus enwebekayo efika ku-420–450 GPa, eqinisekisa ukusebenza okuzinzile ngaphansi kwemithwalo esindayo nokudlidliza.
Ukuphambuka okuncane kokushisa: I-coefficient ephansi kakhulu yokwanda kokushisa (i-CTE), okuqinisekisa ukuzinza kokukhanya ezindaweni ezishintshashintshayo zokushisa.
Ukumelana nokushaqeka kokushisa kanye nokugqwala: Izinzile ezindaweni ezine-asidi/alkali futhi imelana nokushintshashintsha kwezinga lokushisa okusheshayo.
Isakhiwo esincane esiminyene, esingenazo izimbobo: Ubuningi obufika ku-3.14 g/cm³ ngaphandle kokufaka izikhala ezisele ngemuva komshini, okunikeza ukubonakaliswa okuhle kakhulu kanye nobuqotho besakhiwo.

Izicelo

I-infrared optics: Izinhlelo zokuthwebula izithombe ze-infrared eziphakathi nezikude, amakhamera okushisa, kanye ne-surveillance optics.
I-Laser kanye ne-optoelectronics: Izibuko ze-laser ezinamandla aphezulu, isiteringi se-beam, kanye nezinhlangano ze-reflective optical.

Imibuzo Evame Ukubuzwa

Q1: Ingabe isibuko se-SiC siyabonakalisa kumaza okukhanya abonakalayo?
A1: I-substrate ngokwayo ayibonakali, kodwa ngezingubo ezifanele ezibonisa ukukhanya (zensimbi noma ze-dielectric), izibuko ezisicaba ze-SiC zingasebenza kahle kuma-wavelengths abonakalayo, e-infrared, ngisho nase-laser.

Umbuzo 2: Yiziphi izinzuzo ezinikezwa yi-SiC kunezibuko zengilazi noma zensimbi?
A2: I-SiC ilula kakhulu, iqinile, futhi izinzile kakhulu ekushiseni kunezingqimba zengilazi noma zensimbi. Ihlala isikhathi eside kakhulu ezindaweni ezinzima noma ezisendaweni.

Umbuzo 3: Ingabe izibuko ezisicaba ze-SiC zingasetshenziswa ezinhlelweni ze-laser ezinamandla aphezulu?
A3: Yebo. Njengoba ine-conductivity enhle kakhulu yokushisa kanye nokuqina kwemishini, ama-substrate e-SiC afanelekela izibuko ze-laser ezinamandla aphezulu noma ezinamandla aphezulu uma zihlanganiswa nezingubo ezifanele.

Q4: Yiliphi izinga lokuthamba elingafinyelelwa?
A4: Ngemva kokupholisha okunembe kakhulu, ukuba yisicaba kungafinyelela ku-≤ 1 μm, ngokulingana kanye nokuba lukhuni kwendawo kulawulwa ukuze kuhlangatshezwane nemininingwane eqinile yokukhanya.
