Si Windows

Silicon yog ib tug mono siv lead ua feem ntau siv nyob rau hauv semi-conductor thiab tsis-absorptive ntawm 1.2μm mus rau 6μm IR cheeb tsam.Nws yog siv ntawm no ua ib qho khoom siv kho qhov muag rau IR cheeb tsam daim ntawv thov.
Silicon yog siv los ua lub qhov rais kho qhov muag feem ntau hauv 3 mus rau 5 micron band thiab ua substrate rau kev tsim cov lim dej kho qhov muag.Cov blocks loj ntawm Silicon nrog lub ntsej muag polished kuj tau ua haujlwm ua neutron lub hom phiaj hauv Physics thwmsim.
Silicon yog loj hlob los ntawm Czochralski rub cov tswv yim (CZ) thiab muaj qee cov pa oxygen uas ua rau lub nqus nqus ntawm 9 microns.Txhawm rau zam qhov no, Silicon tuaj yeem npaj los ntawm Float-Zone (FZ) txheej txheem.Optical Silicon feem ntau maj mam doped (5 mus rau 40 ohm cm) rau kev sib kis zoo tshaj 10 microns.Silicon muaj ib tug ntxiv pass band 30 mus rau 100 microns uas tsuas yog siv nyob rau hauv heev heev resistivity uncompensated cov ntaub ntawv.Doping feem ntau yog Boron (p-type) thiab Phosphorus (n-type).
Daim ntawv thov:
• Zoo tagnrho rau 1.2 txog 7 μm NIR daim ntawv thov
• Broadband 3 mus rau 12 μm anti-reflection txheej
• Zoo tagnrho rau daim ntaub ntawv rhiab heev
Feature:
• Cov qhov rais silicon no tsis kis ntawm thaj tsam 1µm lossis qis dua, yog li nws daim ntawv thov tseem ceeb yog nyob rau thaj tsam IR.
• Vim tias nws cov thermal conductivity siab, nws yog qhov tsim nyog rau kev siv los ua lub hwj chim laser iav
▶ Silicon windows muaj lub ci ntsa iab hlau;nws reflects thiab absorbs tab sis tsis kis nyob rau hauv cov cheeb tsam pom.
▶ Silicon qhov rais nto qhov kev xav tau ua rau kev xa tawm poob ntawm 53%.( ntsuas cov ntaub ntawv 1 nto reflection ntawm 27%)
