Ko te arotahi Germanium he arotahi whatu i hangaia mai i te germanium.Ko te Germanium (Ge) he rawa tioata me te taupū refractive teitei rawa (4.002@11µm) o nga rauemi infrared e whakamahia nuitia ana.He iti ano te mararatanga, te pakeke me te kiato.Na te whanui o te awhe tuku (neke atu i te 45% i roto i te roopu 2-12 micron) me te puatakore ki te UV me te marama ka kitea, he pai te Germanium mo te tono IR penei i nga punaha whakaata waiariki, tono mara infrared me nga taputapu tātari tika.
Ko te Germanium hoki kei raro i te rerenga waiariki.Ma te tipu o te pāmahana, ka tino tere te whakauru.Na tenei awenga omaoma wera, kaore e pai te whakamahi i te arotahi germanium ki te wera i runga ake i te 100°C.
Ka taea e te Wavelength Infrared te hanga momo ahua o te arotahi germanium me nga papa rererangi, concave, convex, aspheric me nga papa rereke.Ko te Germanium te mea rongonui mo nga punaha whakahaere i roto i te rohe 3-5, 8-12µm ranei, me nga paninga anti-whakaata (AR coating), ka taea te kawe ake ki te 97.5-98.5% i runga i te bandwidth o te paninga.Ka taea hoki e tatou te tono paninga waro rite taimana (paninga DLC), paninga roa teitei ranei (whakakikorua HD) ki runga i te mata o te arotahi hei whakamarumaru atu i te pakaru me te pa.
Ko te roangaru infrared e hanga ana i te kounga o te ahua porowhita me te arotahi germanium aspheric.Ka taea e ratou te arotahi, te rereke ranei i te kurupae marama taumai ki te whakatutuki i nga whakaritenga motuhake o te punaha infrared.Ko te tono ko te whakamaarama waiariki, thermograph, kurupae collimating, tātari hihinga me te aha atu.
