ZnSe Windows
ZnSe imhando yeyero uye yakajeka mulit-cystal zvinhu, saizi yecrystalline particle inenge 70um, kuendesa kureba kubva 0.6-21um isarudzo yakanakisa kune dzakasiyana siyana dzeIR application dzinosanganisira yakakwirira simba CO2 laser masisitimu.
Zinc Selenide ine yakaderera IR kutorwa.Izvi zvakanakira kufungidzira kwekupisa, uko tembiricha yezvinhu zviri kure inowonekwa kuburikidza neayo blackbody radiation spectrum.Kujeka kwewavelength kwakakosha pakufungidzira tembiricha yekamuri zvinhu, izvo zvinopenya pakakwirira wavelength inosvika gumi μm nekudzika kwakanyanya.
ZnSe ine yakakwira index yerefraction iyo inoda anti-reflection coating kuti iwane yakakwirira kutapurirana.Yedu Broadband AR coating yakagadziridzwa 3 μm kusvika 12 μm.
Znse zvinhu zvakagadzirwa nekemikari vapor deposition (CVD) zvakanyanya haipo kunyura kwetsvina, kuparadzira kukuvadza kwakadzikira.Nekuda kwekudzika kwakanyanya kunyura kwechiedza che10.6um wavelength, saka ZnSe ndiyo yekutanga sarudzo yekugadzira zvinhu zvemaziso epamusoro-simba Co2 laser system.Uyezve ZnSe zvakare imhando yezvinowanzo shandiswa zvinhu kune akasiyana optical system mune yakazara kufambisa waveband.
Zinc Selenide inogadzirwa ne synthesis kubva kuZinc vapor uye H2Se gasi, ichigadzira semashizha paGraphite susceptors.Zinc Selenide ndeye microcrystalline muchimiro, saizi yezviyo ichidzorwa kuburitsa simba rakawanda.Single crystal ZnSe inowanikwa, asi haina kujairika asi yakanzi ine yakaderera kunyura uye nekudaro inoshanda zvakanyanya kune CO2 optics.
Zinc Selenide inoita oxidize zvakanyanya pa 300°C, inoratidza deformation yepurasitiki panenge pa500°C uye inopatsanura 700°C.Nekuchengetedza, Zinc Selenide windows haifanirwe kushandiswa pamusoro pe250 ° C mumhepo yakajairika.
