    Germanium a matsayin mono crystal da farko da aka yi amfani da shi a cikin semi-conductor ba mai sha ba ne a yankunan 2μm zuwa 20μm IR.Ana amfani dashi anan azaman kayan aikin gani don aikace-aikacen yanki na IR.
    Germanium babban abu ne wanda ake amfani dashi don kera Attenuated Total Reflection (ATR) prisms don duban gani.Its refractive index ne irin wannan cewa Germanium yin tasiri na halitta 50% beamsplitter ba tare da bukatar coatings.Har ila yau, Germanium ana amfani da shi sosai a matsayin maƙalar don samar da matatun gani.Germanium ya ƙunshi duka 8-14 micron thermal band kuma ana amfani dashi a tsarin ruwan tabarau don hoton zafi.Ana iya lulluɓe Germanium tare da lu'u-lu'u wanda ke samar da na'urar gani mai ƙarfi ta gaba.
    Ana shuka Germanium ta hanyar amfani da fasahar Czochralski ta wasu ƙananan masana'antun a Belgium, Amurka, China da Rasha.Ma'anar refractive na Germanium yana canzawa da sauri tare da zafin jiki kuma kayan ya zama mara kyau a kowane tsayin raƙuman ruwa kadan sama da 350K yayin da ratar band ɗin ke ambaliya da thermal electrons.
