I-Germanium njengekristale e-mono esetyenziswa ikakhulu kwi-semi-conductor ayifuni ukufunxa kwi-2μm ukuya kwi-20μm yemimandla ye-IR.Isetyenziswa apha njengecandelo le-optical kwizicelo zengingqi ye-IR.
I-Germanium sisixhobo sesalathisi esiphezulu esisetyenziselwa ukwenza iiprism ze-Attenuated Total Reflection (ATR) ukwenzela i-spectroscopy.Isalathiso salo sokuphindaphinda sinjalo ukuba i-Germanium yenza i-beamsplitter yendalo esebenzayo ye-50% ngaphandle kwemfuneko yeengubo.IGermanium ikwasetyenziswa kakhulu njenge substrate yokuvelisa izihluzo zamehlo.I-Germanium igquma yonke i-8-14 micron thermal band kwaye isetyenziswa kwiinkqubo zelensi kumfanekiso wobushushu.I-Germany inokuba yi-AR iqatywe ngeDayimane ivelisa i-optic yangaphambili eyomeleleyo.
IGermanium ikhuliswa kusetyenziswa ubuchule beCzochralski ngabavelisi abambalwa eBelgium, USA, China naseRussia.Isalathiso se-refractive se-Germanium sitshintsha ngokukhawuleza ngeqondo lobushushu kwaye imathiriyeli iba yi-opaque kuwo onke amaza amaza angaphezulu kancinane kwe-350K njengoko umsantsa webhendi uphuphuma ngee-electron ezishisayo.
Isicelo:
• Ilungele izicelo ezikufutshane ne-IR
• Ibroadband 3 ukuya 12 μm anti-reflection umaleko
• Ilungele izicelo ezifuna usasazo oluphantsi
• Inkulu kusetyenziso lwelaser yamandla aphantsi e-CO2
Uphawu:
• Ezi festile zegermanium azihambisi kwingingqi ye-1.5µm okanye ngaphantsi, ngoko ke usetyenziso lwayo oluphambili lukwimimandla ye-IR.
• Iifestile ze-Germanium zingasetyenziswa kwimifuniselo eyahlukeneyo ye-infrared.
