SWIR LEDs feem ntau tsim tawm ntawm Arsenide, Gallium, thiab Indium. Cov thev naus laus zis feem ntau yog siv InGaAs lattice txhawm rau txhawm rau txhawm rau ntes thiab tawm lub teeb uas pom muaj nyob hauv SWIR wavelength.
Raws li tau hais ua ntej, nws yog ib qho tseem ceeb los xaiv qhov tseeb SWIR illumination thiab qhov zoo tshaj plaws wavelength rau kev ua tau zoo. SWIR LEDs yuav tsum ua raws li tib txoj cai siv rau kev tshuaj xyuas lub teeb pom kev.
Nyob ntawm daim ntawv thov, nws tuaj yeem siv cov lus lossis ntau lub SWIR illuminators. Qhov ntawd suav nrog cov teeb pom kev tsaus ntuj, lub teeb nraub qaum, lub teeb pem hauv ntej (on-axis), dome teeb, bar teeb, lub teeb lub nplhaib, thiab lwm yam. Thaum siv SWIR LEDs, cov txiaj ntsig tau zoo tshaj plaws tau txais nrog kev sib txuam siab. Ntxiv rau, nws yuav tsum muaj qhov tsim nyog siv, thaj tsam loj, thiab qhov sib txawv yam tsis muaj qhov xav tau tshwj xeeb.
