Txheem ZnS (Zinc Sulphide) ua los ntawm CVD (Tshuaj Vapor Deposition) cov txheej txheem los nrhiav kev xa mus rau high school, CVD ZnS yog cov khoom siv polycrystalline, nws yog qhov zoo qhov rais thiab cov khoom siv rau cov duab thaij duab sab qaum ntuj loj rau kev siv tub rog lossis lwm qhov chaw sib zog, rau nws cov kis tau tus mob siab, kev kho qhov muag zoo, kev ua kom tsis muaj zog, qhov nyuaj, thiab tshuaj tsis muaj zog. CVD ZnS yog cheem tsis tau zoo, muaj kev ntshiab heev, ua ntu zus thiab yooj yim machined. Zinc sulfide qhia txog qib siab ntawm qhov Performance index ntawm refraction homogeneity thiab muaj kev sib thooj li ntawm 3-12 micron waveband. Nrog kho qhov muag zoo thiab cov khoom siv zoo heev, CVD ZnS tau muab siv rau hauv ntau daim ntawv thov tub rog uas yuav tsum tau ua kom muaj kev sib thooj rau cov cheeb tsam hostile.
Multispectral ZnS yog tsim los ntawm Standard ZnS los ntawm qhov kev tso tawm tom qab qhov sov isostatic (HIP). Cov txheej txheem no kis tau tus kab mob kis ntawm 0.4 mus rau 12 microns, yog li ua rau cov khoom zoo li dej nrog tsawg heev thiab tawg. Multispectral ZnS qhia tau zoo heev kis tau hla lub pom mus rau sab nrauv ntais ntawm sab qaum ntiv taw infrared waveband zoo tsim nyog rau cov ntawv thov uas yuav tsum tau txhaj ib txoj kab dav rau txoj kab teeb rau ntau txoj kab sib txawv.
