    ZnSe ndi mtundu wachikasu komanso wowonekera mulit-cystal zakuthupi, kukula kwa tinthu tibulu tating'ono ndi pafupifupi 70um, kufalitsa osiyanasiyana kuchokera ku 0.6-21um ndichisankho chabwino kwambiri pazogwiritsa ntchito za IR kuphatikiza mitundu yayikulu yama CO2 laser system.
    Zinc Selenide ali ndi mayendedwe otsika a IR. Izi ndizopindulitsa pakujambula kwamatenthedwe, komwe kutentha kwa zinthu zakutali kumazindikirika kudzera pamagetsi awo amtundu wakuda. Kuwonetsera kwazitali zazitali ndikofunikira pakujambula kutentha kwa chipinda, chomwe chimatuluka pamtunda wa pafupifupi 10 μm motsika kwambiri.
    ZnSe ili ndi cholozera chokwera kwambiri chomwe chimafuna chovala chotsutsa kuti chikwaniritse kufalikira kwakukulu. Chovala chathu chachikulu cha AR chimakonzedwa kwa 3 μm mpaka 12 μm.
    Zinthu za Znse zopangidwa ndi mankhwala otulutsa nthunzi (CVD) kwenikweni sizipezeka kuyamwa kosayera, kuwonongeka kofalikira kumakhala kotsika kwambiri. Chifukwa chotsika kwambiri kwa kuwala kwa 10.6um wavelength, kotero ZnSe ndiye chinthu choyambirira kusankha zinthu zopangira mawonekedwe amtundu wapamwamba wa CO2 laser. Kuphatikiza apo ZnSe ndi mtundu wazinthu zomwe zimagwiritsidwa ntchito mosiyanasiyana pamawayilesi athunthu.
    Zinc Selenide imapangidwa ndi kaphatikizidwe kuchokera ku Zinc vapor ndi H2Se gasi, ndikupanga ngati ma sheet pa graphite susceptors. Zinc Selenide ndi microcrystalline yomwe imapangidwira, kukula kwa tirigu kumayang'aniridwa kuti kutulutsa mphamvu zambiri. Crystal imodzi ZnSe imapezeka, koma siofala koma akuti imakhala ndi mayamwidwe ochepa motero imagwira ntchito kwambiri kwa ma CO2 optics.

    Zinc Selenide imakhudzanso kwambiri pa 300 ° C, imawonetsa kupindika kwa pulasitiki pafupifupi 500 ° C ndipo imasiyanitsa pafupifupi 700 ° C. Kuti mukhale otetezeka, mawindo a Zinc Selenide sayenera kugwiritsidwa ntchito pamwamba pa 250 ° C m'malo abwinobwino.

    Mapulogalamu:
    • Chothandiza pamagetsi apamwamba a CO2 laser
    • 3 mpaka 12 μm burodibandi IR antireflection zokutira
    • Zinthu zofewa sizikulimbikitsidwa m'malo ovuta
    • Laser yamphamvu komanso yotsika,
    • makina a laser,
    • sayansi yamankhwala,
    • zakuthambo ndi masomphenya a usiku a IR.
    Mawonekedwe:
    • Kuwonongeka kochepa.
    • Kutsika kwambiri kwa IR
    • Kwambiri kugonjetsedwa ndi matenthedwe mantha
