Zinc Selenide (ZnSe)
Zinc Selenide ichiedza-yero, yakasimba musanganiswa inosanganisira zinc uye selenium. Iyo inogadzirwa nekubatanidzwa kweZinc vapor uye H2Se gasi, kuumba semashizha pane graphite substrate. ZnSe ine index of refraction ye 2.403 pa 10.6 µm, nekuda kwehunhu hwayo hwekufungidzira, kunyura kwakaderera coefficient uye kushomeka kwepamusoro kuvhundutsa kwekupisa, inowanzoshandiswa mumasisitimu emeso anosanganisa CO.2laser (inoshanda pa10.6 μm) ine isingadhure HeNe alignment lasers. Nekudaro, yakapfava uye inokwenya nyore. Kutapurirana kwayo kwakasiyana 0.6-16 µm kunoita kuti ive yakanakira IR zvikamu (mahwindo nemalenzi) & yeanoonekwa ATR prisms, uye anoshandiswa zvakanyanya mumasisitimu ekufungidzira anopisa. ZnSe inotumirawo chimwe chiedza chinooneka uye ine kunyura kwakaderera muchikamu chitsvuku chechimiro chinooneka, kusiyana negermanium nesilicon, nokudaro zvichibvumira kurongeka kwemaziso.
Zinc Selenide oxidizes zvakanyanya pa 300 ℃, inoratidza deformation yepurasitiki paanenge 500 ℃ uye inoparadzanisa nezve 700 ℃. Nekuchengetedza, mahwindo eZnSe haafanire kushandiswa pamusoro pe250 ℃ munzvimbo yakajairika.

Mazano: Paunenge uchishanda neZinc Selenide, munhu anofanira kugara akapfeka magurovhosi, izvi zvinodaro nekuti zvinhu zvine njodzi. Kuti uchengetedzeke, ndapota tevera matanho ese akakodzera, kusanganisira kupfeka magirovhosi paunenge uchibata chinhu ichi uye kunyatsogeza maoko ako mushure.
Kuti uwane rumwe ruzivo rwakadzama rwe data, ndapota tarisa yedu katalogi optics kuti uone yedu yakazara sarudzo ye optics yakagadzirwa kubva zinc selenide.
