    Vhidhiyo

    ZnSe rudzi rweyero uye yakajeka mulit-cystal zvinhu, saizi yekristallini inokwana inenge 70um, ichiendesa kubva pa0.6-21um isarudzo yakanakisa yemhando dzakasiyana dze IR zvinoshandiswa kusanganisira yakakura simba CO2 laser masystem.
    Zinc Selenide ine yakaderera IR yekumwa. Izvi zvinobatsira pakufungidzira kwekushisa, uko tembiricha yezvinhu zviri kure zvinozivikanwa kuburikidza neyavo blackbody radiation spectrum. Kureba kwemarefu kureba kwakakosha mukufungidzira tembiricha yemukamuri zvinhu, izvo zvinopenya pakakwirira wavelength ingangoita 10 μm ine yakadzika kwazvo kusimba.
    ZnSe ine yakakwira indekisi yekubvisa iyo inoda anti-kuratidza kuratidzwa kuti ibudirire kutapurirana kwakakwirira. Yedu Broadband AR yekupfeka yakagadziridzwa ye3 μm kusvika 12 μm.
    Znse zvinhu zvakagadzirwa nemakemikari vapor deposition (CVD) hazviite kusasviba kwekutora, kuparadzira kukuvara kwakadzika kwazvo. Nekuda kwekutsvaira kwakadzika kwechiedza kwe10,6um wavelength, saka ZnSe ndiyo yekutanga sarudzo yekugadzira zvinhu zvemagetsi-emagetsi-CO2 laser system. Uyezve ZnSe iriwo mhando yezvinhu zvakajairika zvinoshandiswa zveanosiyana masystem system mukutakura kwese waveband.
    Zinc Selenide inogadzirwa ne synthesis kubva kuZinc vapor uye H2Se gasi, ichiita semashizha paGrafite susceptors. Zinc Selenide ndeye microcrystalline muchimiro, saizi yezviyo iri kudzorwa kuti ibudise simba rakanyanya. Kristaro imwechete ZnSe inowanikwa, asi haina kujairika asi yakanzi iine kunyura kwakadzika uye nekudaro inoshanda zvakanyanya kune CO2 optics.

    Zinc Selenide inosanganisa zvakanyanya pa300 ° C, inoratidzira deformation yepurasitiki ingangoita 500 ° C uye inoparadzanisa nezve 700 ° C. Zvekuchengetedza, Zinc Selenide windows haifanire kushandiswa pamusoro pe250 ° C mune yakasarudzika mhepo.

    Mafomu:
    • Yakanaka kune yakakwira simba CO2 laser kunyorera
    • 3 kusvika 12 μm Broadband IR antireflection coating

    Yakakwirira uye yakaderera simba laser,
    • laser system,
    • sainzi yekurapa,
    • nyeredzi uye chiratidzo cheUS usiku.
    Zvimiro:
    • Kukuvara kwakaderera kwekupararira.
    • Yakanyanya yakadzika IR kutora
    • Yakanyanya kusagadzikana nekupisa kwekupisa
    • Kupararira kwakadzika uye kudzika kwekutora kwakaringana
