    Iparameters technical

    Igermanium njengekristale yemono esetyenziswa ikakhulu kwi-semi-conductor ayisiyomfutho kwi-2μm ukuya kwi-20μm ye-IR. Isetyenziswa apha njengecandelo elibonakalayo lezicelo zommandla we-IR.
    IGermanium sisalathiso esiphakamileyo semathiriyeli esetyenziselwa ukwenza iAttenuated Total Reflection (ATR) prism ye-spectroscopy. Isalathiso sayo sokukhupha into yokuba iGermanium yenze i-beamsplitter yendalo eyi-50% ngaphandle kwemfuneko yokwaleka. IGermanium ikwasetyenziswa kakhulu njengesiqhekeza semveliso yezihluzi zamehlo. IGermanium igubungela yonke i-8-14 micron thermal band kwaye isetyenziswa kwiinkqubo zeelensi zokucinga ngokufudumeleyo. Igermanium inokuba yi-AR isongelwe ngeDayimane evelisa i-optic engaphambili enzima kakhulu.
    IGermanium ikhuliswa kusetyenziswa ubuchule beCzochralski ngenani elincinci labenzi baseBelgium, eUSA, China naseRussia. Isalathiso sokubonisa seGermanium sitshintsha ngokukhawuleza ngamaqondo obushushu kwaye imathiriyeli iba opaque kuwo onke amaza ombane ngaphezulu kwe-350K njengoko isikhewu sebhendi sikhukula ngee-elektroni ezishushu.
    Isicelo:
    • Ilungele ukusetyenziswa kwe-IR ekufuphi
    • Ibhendi ebanzi ye-3 ukuya kwi-12 μm yokulwa nembonakalo
    • Ilungele ukusetyenziswa kwezicelo ezifuna ukusasazeka okuphantsi
    • Ilungele ukusetyenziswa kwamandla asezantsi e-CO2 laser
    Phawu:
    Ezi festile zegermanium azihambisi indawo eyi-1.5µm okanye ngaphantsi, ke ngoko eyona nto iphambili kuyo kukusetyenziswa kwemimandla ye-IR.
    • Iifestile zeGermanium zinokusetyenziswa kuvavanyo lwee-infrared ezahlukeneyo.
