(Multi-spectrual) Zinc Sulfide (ZnS)
Zinc Sulfide yog tsim los ntawm kev sib txuas los ntawm Zinc vapor thiab H2S roj, tsim los ua cov ntawv ntawm Graphite susceptors. Nws yog microcrystalline nyob rau hauv cov qauv, lub grain loj raug tswj los tsim lub zog siab tshaj plaws. ZnS kis tau zoo nyob rau hauv IR thiab pom spectrum, nws yog ib qho kev xaiv zoo heev rau thermal imaging. ZnS yog ib qho nyuaj, cov qauv muaj zog thiab cov tshuaj tiv thaiv ntau dua li ZnSe, nws feem ntau yog qhov kev xaiv zoo dua lwm cov ntaub ntawv IR. Multi-spectral qib yog ces Kub Isostatically Pressed (HIP) los txhim kho qhov nruab nrab IR kis tau tus mob thiab tsim daim ntawv pom tseeb. Ib leeg siv lead ua ZnS muaj, tab sis tsis muaj ntau. Multi-spectral ZnS (dej-ntshiab) yog siv rau IR qhov rais thiab lo ntsiab muag nyob rau hauv lub thermal band ntawm 8 - 14 μm qhov twg qhov siab tshaj plaws kis tau tus mob thiab qis tshaj yog yuav tsum tau. Tsis tas li ntawd nws raug xaiv los siv qhov pom kev sib dhos yog qhov zoo dua.

Daim duab
Txoj cai daim duab yog kis tau tus mob nkhaus ntawm 10 mm tuab, uncoated ZnS substrate
Lub tswv yim: Zinc Sulphide oxidizes heev ntawm 300 ° C, nthuav tawm cov yas deformation ntawm li 500 ° C thiab dissociates txog 700 ° C. Rau kev nyab xeeb, Zinc Sulphide windows yuav tsum tsis txhob siv siab tshaj 250 ° C hauv qhov qub
huab cua.
