Short-Wave Infrared (SWIR) yog ib qho tshwj xeeb tsim kho qhov muag lens tsim los ntes luv-yoj infrared lub teeb uas tsis ncaj qha perceivable los ntawm tib neeg lub qhov muag. Cov kab no yog kev cai tsim raws li lub teeb nrog wavelengths spanning ntawm 0.9 mus rau 1.7 microns. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub lens luv-yoj infrared hinges ntawm cov khoom sib kis ntawm cov khoom siv rau ib lub teeb ntawm lub teeb, thiab nrog kev pab los ntawm cov khoom siv kho qhov muag tshwj xeeb thiab txheej txheej tshuab, lub lens tuaj yeem ua tau zoo ua lub teeb luv luv infrared thaum tiv thaiv pom. lub teeb thiab lwm yam tsis xav tau wavelengths.
Nws cov yam ntxwv tseem ceeb muaj xws li:
1. High transmittance thiab spectral selectivity:SWIR lo ntsiab muag siv cov khoom siv kho qhov muag tshwj xeeb thiab txheej thev naus laus zis kom tau txais kev xa tawm siab nyob rau hauv lub luv-yoj infrared band (0.9 mus rau 1.7 microns) thiab muaj spectral selectivity, ua kom yooj yim rau kev txheeb xyuas thiab ua cov wavelengths ntawm lub teeb infrared thiab inhibition ntawm lwm cov wavelengths ntawm lub teeb. .
2. Tshuaj tiv thaiv corrosion thiab thermal stability:Cov khoom siv thiab txheej txheej ntawm lub lens qhia tau zoo heev ntawm cov tshuaj lom neeg thiab thermal stability thiab tuaj yeem txhawb nqa kev ua haujlwm kho qhov muag nyob rau hauv qhov kub hloov pauv thiab ntau yam xwm txheej ib puag ncig.
3. Kev daws teeb meem siab thiab qis distortion:SWIR lo ntsiab muag manifests siab daws teeb meem, tsis tshua muaj distortion, thiab ceev teb optical cwj pwm, ua kom tiav cov kev xav tau ntawm high-txhais duab.
Shortwave infrared lo ntsiab muag tau siv dav hauv kev tshuaj xyuas kev lag luam. Piv txwv li, nyob rau hauv cov txheej txheem tsim khoom semiconductor, SWIR lo ntsiab muag tuaj yeem kuaj pom qhov tsis zoo hauv silicon wafers uas nyuaj rau pom hauv qab lub teeb pom kev. Shortwave infrared imaging thev naus laus zis tuaj yeem txhim kho qhov raug thiab ua haujlwm ntawm kev tshuaj xyuas wafer, yog li txo cov nqi tsim khoom thiab txhim kho cov khoom zoo.
Short-wave infrared lo ntsiab muag ua lub luag haujlwm tseem ceeb hauv kev tshuaj xyuas semiconductor wafer. Txij li lub teeb infrared shortwave tuaj yeem permeate silicon, tus cwj pwm no txhawb lub zog luv-yoj infrared lo ntsiab muag txhawm rau txheeb xyuas qhov tsis xws luag hauv silicon wafers. Piv txwv li, lub wafer tej zaum yuav muaj fissures vim residual kev nyuaj siab thaum lub sij hawm tsim cov txheej txheem, thiab cov fissures no, yog hais tias undetected, yuav ncaj qha cuam tshuam rau cov tawm los thiab raug nqi ntawm qhov kawg ua tiav IC nti. Los ntawm leveraging luv-yoj infrared lo ntsiab muag, xws li cov tsis xws luag yuav pom tau zoo, yog li txhawb ntau lawm efficiency thiab cov khoom zoo.
Hauv kev siv tswv yim, cov lo ntsiab muag luv luv infrared tuaj yeem muab cov duab zoo sib xws, ua rau cov teeb meem me me pom tau meej. Daim ntawv thov ntawm cov cuab yeej tshawb nrhiav no tsis yog tsuas yog txhim kho qhov tseeb ntawm kev tshawb nrhiav tab sis kuj txo tus nqi thiab lub sijhawm ntawm kev tshawb nrhiav phau ntawv. Raws li kev tshawb fawb kev lag luam, qhov kev thov rau luv-yoj infrared lo ntsiab muag nyob rau hauv lub semiconductor nrhiav kom tau kev lag luam yog nce xyoo los ntawm lub xyoo thiab xav kom muaj kev ruaj ntseg txoj kev loj hlob nyob rau hauv ob peb xyoos tom ntej no.
