(Multi-spectrual) Zinc Sulfide (ZnS)
Hana ʻia ʻo Zinc Sulfide e ka synthesis mai ka Zinc vapor a me ke kinoea H2S, i hana ʻia ma ke ʻano he mau pepa ma luna o nā susceptors Graphite. He microcrystalline ia i ka hoʻolālā, ke kāohi ʻia ka nui o ka palaoa e hana i ka ikaika kiʻekiʻe. Hoʻouna maikaʻi ʻo ZnS i ka IR a ʻike ʻia, he koho maikaʻi loa ia no ke kiʻi wela. ʻOi aku ka paʻakikī o ka ZnS, ʻoi aku ka ikaika a ʻoi aku ka paʻa o ke kemika ma mua o ZnSe, ʻoi aku ka maʻamau o ke koho ʻoi aku ka maikaʻi ma mua o nā mea IR ʻē aʻe. A laila, ʻo ka Hot Isostatically Pressed (HIP) ka papa multi-spectral no ka hoʻomaikaʻi ʻana i ka hoʻouna ʻana i ka waena IR a hana i ke ʻano akaka. Loaʻa ka ZnS kristal hoʻokahi, akā ʻaʻole maʻamau. Hoʻohana ʻia ʻo ZnS multi-spectral (wai-māmā) no nā puka makani IR a me nā lens i loko o ka puʻupuʻu wela o 8 - 14 μm kahi e koi ʻia ai ka hoʻouna kiʻekiʻe a me ka absorption haʻahaʻa. Ua koho ʻia nō hoʻi no ka hoʻohana ʻana i kahi pono o ka alignment ʻike ʻia.

Manaʻo Manaʻo: Zinc Sulphide oxidize nui ma 300°C, hōʻike i ka plastic deformation ma kahi o 500°C a hoʻokaʻawale ma kahi o 700°C. No ka palekana, ʻaʻole pono e hoʻohana ʻia nā puka makani Zinc Sulphide ma luna o 250°C ma ke ʻano maʻamau

No ka ʻikepili kikoʻī hohonu, e ʻoluʻolu e nānā i kā mākou papa inoa optics e ʻike i kā mākou koho piha o nā optics i hana ʻia mai ka zinc sulfide.
