Germanium (zeeg)
Germanium muaj qhov tsaus grey smoky tsos nrog lub siab refractive Performance index ntawm 4.024 ntawm 10.6 µm & tsawg optical dispersion.Ge yog siv los tsim Attenuated Total Reflection (ATR) prisms rau spectroscopy.Nws qhov refractive index ua rau muaj txiaj ntsig zoo ntawm 50% beamsplitter yam tsis xav tau txheej txheej.Ge kuj tseem siv dav los ua lub substrate rau kev tsim cov lim dej kho qhov muag.Ge npog tag nrho 8 - 14 µm thermal band thiab siv nyob rau hauv lub lens tshuab rau thermal imaging.Germanium tuaj yeem ua AR coated nrog pob zeb diamond ua rau lub ntsej muag tawv tawv heev.Tsis tas li ntawd, Ge yog inert rau huab cua, dej, alkalis, thiab cov kua qaub (tshwj tsis yog nitric acid), nws muaj qhov ntom ntom nrog Knoop Hardness (kg / mm2): 780.00 tso cai rau nws ua tau zoo rau kev kho qhov muag hauv qhov xwm txheej rugged.Txawm li cas los Ge's kis tau tus mob yog kub rhiab heev, qhov nqus yuav loj heev uas germanium yog ze li ntawm opaque ntawm 100 ° C thiab kiag li tsis-transmissive ntawm 200 ° C.

Tswv yim: Thaum ua hauj lwm nrog Germanium, ib tug yuav tsum yeej ib txwm hnav hnab looj tes, qhov no yog vim hais tias plua plav los ntawm cov khoom yog txaus ntshai.Rau koj txoj kev nyab xeeb, thov ua raws li txhua yam kev ceev faj kom raug, suav nrog cov hnab looj tes thaum tuav cov khoom no thiab ntxuav koj txhais tes kom huv si tom qab ntawd.
Yog xav paub ntxiv cov ntaub ntawv tshwj xeeb hauv qhov tob, thov saib peb cov catalog optics kom pom peb cov kev xaiv ua tiav ntawm optics ua los ntawm germanium.
