ZnSe ndi mtundu wa zinthu zachikasu komanso zowoneka bwino za mulit-cystal, kukula kwa crystalline tinthu tating'onoting'ono tating'onoting'ono ta 70um, kufalikira kuchokera ku 0.6-21um ndi chisankho chabwino kwambiri pazogwiritsa ntchito zosiyanasiyana za IR kuphatikiza makina apamwamba a CO2 laser.
Zinc Selenide ili ndi mayamwidwe otsika a IR.Izi ndizothandiza pazithunzithunzi zotentha, pomwe kutentha kwa zinthu zakutali kumazindikiridwa kudzera mu radiation yakuda.Kuwonekera kwa kutalika kwa mafunde ndikofunika kwambiri pojambula zinthu za kutentha kwa chipinda, zomwe zimawonekera pamtunda wapamwamba wa pafupifupi 10 μm ndi kutsika kwambiri.
ZnSe ili ndi index yayikulu ya refraction yomwe imafunikira anti-reflection coating kuti ikwaniritse kufalikira kwakukulu.Kupaka kwathu kwa Broadband AR kumakongoletsedwa ndi 3 μm mpaka 12 μm.
Znse zopangidwa ndi chemical vapor deposition(CVD) kwenikweni sizimayamwa zonyansa, kuwonongeka komwaza ndikochepa kwambiri.Chifukwa cha kuyamwa kochepa kwambiri kwa 10.6um wavelength, kotero ZnSe ndiye chinthu choyamba chosankha kupanga zinthu zowoneka bwino zamagetsi amphamvu kwambiri a Co2 laser.Kuphatikiza apo, ZnSe ndi mtundu wazinthu zomwe zimagwiritsidwa ntchito wamba pamakina osiyanasiyana opangira ma waveband.
Zinc Selenide amapangidwa ndi kaphatikizidwe kuchokera ku Zinc vapor ndi H2Se gesi, kupanga ngati mapepala pa Graphite susceptors.Zinc Selenide ndi microcrystalline mu kapangidwe kake, kukula kwambewu kumayendetsedwa kuti apange mphamvu zambiri.Single crystal ZnSe ikupezeka, koma sizodziwika koma idanenedwa kuti imayamwa pang'ono ndipo motero imakhala yothandiza kwambiri pa CO2 Optics.
Zinc Selenide imatulutsa okosijeni kwambiri pa 300 ° C, imawonetsa kupunduka kwa pulasitiki pafupifupi 500 ° C ndikulekanitsa pafupifupi 700 ° C.Kuti mutetezeke, mazenera a Zinc Selenide sayenera kugwiritsidwa ntchito pamwamba pa 250 ° C mumlengalenga wabwinobwino.
Mapulogalamu:
• Ndibwino kuti mugwiritse ntchito laser ya CO2 laser
• 3 mpaka 12 μm burodibandi IR zokutira antireflection
• Zinthu zofewa zomwe sizimalimbikitsidwa m'malo ovuta
• Laser yamphamvu komanso yotsika,
• laser system,
• sayansi ya zamankhwala,
• zakuthambo ndi IR usiku masomphenya.
Mawonekedwe:
• Kuwonongeka kobalalika kochepa.
• Mayamwidwe otsika kwambiri a IR
• Kugonjetsedwa kwambiri ndi kutentha kwa kutentha
• Kubalalika kochepa komanso kocheperako kuyamwa kochepa
