Thawj kauj ruam hauv txhua txoj kev tsim kho kho qhov muag yog xaiv cov khoom siv kho qhov muag. Qhov ntsuas kho qhov muag (cov nqi kho mob, kev sib txuas, cov khoom siv kub (Hardness Kev ua tau zoo ntawm kho qhov muag thiab tshuab. Kab lus no yuav qhia luv luv cov ntaub ntawv kho qhov muag thiab lawv cov khoom.
Cov ntaub ntawv kho qhov muag yog muab faib rau hauv peb pawg: khoos kas kho qhov muag, kho cov khoom siv kho tshiab thiab tshwj xeeb kho qhov muag.
01 optical iav
Kho lub khob kho qhov muag yog ib qho amorphous (iav) kho qhov muag tshiab uas tuaj yeem hloov lub teeb. Lub teeb dhia dhau los ntawm nws tuaj yeem hloov nws qhov kev paub txog kev tshaj tawm, theem thiab siv. Nws yog feem ntau siv los ua cov khoom siv kho qhov muag siv xws li princs, lo ntsiab muag, iav, iav, iav, iav, iav, iav, iav, iav, iav, iav, iav, iav, iav, iav, iav, iav thiab lim hauv cov twj siv kho tshiab lossis tshuab. Lub khob kho qhov muag muaj siab transparency, tshuaj ruaj khov thiab lub cev sib dhos hauv cov qauv thiab kev ua tau zoo. Nws muaj meej thiab muaj tseeb kho qhov muag. Nyob rau hauv qis-kub lub xeev, kho qhov muag lub ntsej muag khaws cov amorphous qauv ntawm lub xeev kub-ua kua siab. Qhov tsim nyog, cov khoom siv hauv lub cev thiab tshuaj lom neeg ntawm cov iav, thermal conductivity, etcal modulus, etc., yog tib yam nyob rau hauv tag nrho cov lus qhia, uas yog hu ua isotropy.
Cov chaw tsim khoom tseem ceeb ntawm lub khob kho kab mob suav nrog lub teb chaws Yelemees, Corning ntawm Tebchaws Asmeskas, Airara ntawm Nyij Pooj, thiab Domestic Chengdu iav (CDGM), thiab lwm yam.
Cov Lus Qhia Tsis Zoo thiab Kev Rho Tawm Discam

02. Optical Crystal
Kho dua tshiab yog hais txog cov ntaub ntawv siv lead ua siv hauv cov xov tooj ntawm cov khoom siv. Vim yog cov qauv qauv ntawm kev khou muaju, nws tuaj yeem siv dav siv los ua ntau qhov rai, lo ntsiab muag, thiab prisms rau cov kev siv vstaviolet thiab infrared. Raws li cov qauv crystal, nws tuaj yeem faib ua ib qho siv lead ua thiab polycrystalline. Tib cov ntaub ntawv siv ua siv khov kho thiab kev hloov pauv lub teeb, nrog rau cov khoom siv tsis tau yooj yim, yog li ib qho muaju tsuas yog siv hauv khou.
Tshwj xeeb: Cov UV thiab Infrared Crystal Cov Khoom Siv suav nrog: QOS2), Lithcium Fluoride (Foob), silicon (GE), thiab lwm yam)
Sab Nraum Npib, siv cov npe muaj xws li calcarizing muaj xws li calcarite (CACO3), QUBZ (SIRE2), sodium nitrate (nitrate), thiab lwm yam), thiab lwm yam.
Achromatic siv lead ua: Qhov tshwj xeeb dispersion cov yam ntxwv ntawm cov siv lead ua yog siv los ua cov egromatic lub hom phiaj lo ntsiab muag. Piv txwv li, cov fluoride (CAf2) tau ua ke nrog iav los ua ib qho kev ua yeeb yam, uas tuaj yeem tshem tawm cov roj av me me thiab theem nrab spectrum.
Laser Crystal: Siv ua cov khoom ua haujlwm rau cov roj av-lub xeev, xws li ruby, neodej fluoride, neodium aluminium GARNET Crystal, thiab lwm yam.
Crystal cov ntaub ntawv raug muab faib ua ntuj thiab muaj kev loj hlob. Ntuj muaju yog tsawg heev, nyuaj rau loj hlob artificially, txwv nyob rau hauv loj, thiab kim. Feem ntau suav tias yog cov khoom iav tsis txaus, nws tuaj yeem ua haujlwm hauv qhov tsis muaj teeb pom kev thiab yog siv hauv semiconductor thiab laser Industries.
03 Tshwj Xeeb Optical Cov Ntaub Ntawv
a. Iav-Ceramic
Iav-ceramic yog cov khoom siv kho tshiab tshwj xeeb uas tsis yog cov iav lossis tsis muaj lead ua, tab sis qee qhov chaw nyob nruab nrab. Lub ntsiab sib txawv ntawm iav-ceramic thiab dog dig optical iav yog muaj cov qauv siv lead ua. Nws muaj cov qauv crystal zoo tshaj li ceramic. Nws muaj cov yam ntxwv ntawm kev nthuav tawm tsawg thermal uas muaj zog, lub zog siab, nrawm, thiab tsis tshua muaj neeg ruaj khov. Nws yog dav siv nyob rau hauv kev ua cov iav tiaj tiaj, txheem txuj ci, cov tsom iav loj, laser gyroscopes, thiab lwm yam.
Lub thermal expansion coefficient ntawm microcrystalline cov khoom siv kho qhov muag tuaj yeem ncav cuag 0.0 × 0.2 × 10-7 / ℃ (0 ~ 50 ℃)
b. Silicon Carbide
Silicon carbide yog ib qho tshwj xeeb cov khoom siv tej hub uas tseem siv los ua cov khoom siv kho kom zoo nkauj. Silicon carbide muaj cov tawv nqaij uas muaj zog, tsis muaj kev cuam tshuam nrog cov nyhuv muaj zog, thiab cov nyhuv hnyav. Nws suav hais tias yog cov khoom tseem ceeb rau cov tsom iav loj loj thiab yog siv dav hauv ib lub dav hlau, high-zog roj, semiconductors thiab lwm thaj teb.
Cov ntaub ntawv ntawm cov khoom siv kho tshiab kuj tseem tuaj yeem hu tau cov khoom siv tawm. Ntxiv rau cov pawg loj ntawm cov khoom siv kho qhov muag, cov khoom siv fiber ntau, cov khoom siv uaquecical, cov khoom siv ua kua, thiab lwm yam. Kev txhim kho ntawm kev siv kho kho kho tshiab yog qhov tsis sib xws los ntawm kev siv tshuab kho qhov muag. Peb cia siab tias yuav nce qib ntawm kuv lub teb chaws lub tshuab kho qhov muag siv kho kho kho.
