Zinc Selenide (ZnSe)
Zinc Selenide yog lub teeb daj, cov khoom sib xyaw uas muaj zinc thiab selenium. Nws yog tsim los ntawm synthesis ntawm Zinc vapor thiab H2Se gas, sib sau ua nplooj ntawv ntawm graphite substrate. ZnSe muaj qhov Performance index ntawm refraction ntawm 2.403 ntawm 10.6 µm, vim nws cov duab zoo heev, tsis tshua muaj kev nqus coefficient thiab siab tsis kam rau thermal shock, nws feem ntau siv hauv cov tshuab kho qhov muag uas sib txuas CO2laser (ua haujlwm ntawm 10.6 μm) nrog pheej yig HeNe alignment lasers. Txawm li cas los xij, nws yog mos heev thiab yuav khawb tau yooj yim. Nws kis tau tus mob ntawm 0.6-16 µm ua rau nws zoo tagnrho rau IR Cheebtsam (qhov rais thiab lo ntsiab muag) & rau spectroscopic ATR prisms, thiab dav siv nyob rau hauv thermal imaging systems. ZnSe kuj kis tau qee lub teeb pom kev zoo thiab muaj qhov nqus qis hauv qhov liab ntawm qhov pom spectrum, tsis zoo li germanium thiab silicon, yog li tso cai rau kev pom kev kho qhov muag.
Zinc Selenide oxidizes heev ntawm 300 ℃, nthuav tawm cov yas deformation ntawm li 500 ℃ thiab dissociates txog 700 ℃. Rau kev nyab xeeb, ZnSe qhov rais yuav tsum tsis txhob siv siab tshaj 250 ℃ nyob rau hauv ib txwm huab cua.

Tswv yim: Thaum ua hauj lwm nrog Zinc Selenide, ib tug yuav tsum yeej ib txwm hnav hnab looj tes, qhov no yog vim hais tias 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 tiav ntawm optics ua los ntawm zinc selenide.
