    ʻO ZnSe kahi ʻano mea melemele mulit-cystal, ʻo ka nui o ka crystalline particle ma kahi o 70um, ka hoʻouna ʻana mai ka 0.6-21um kahi koho maikaʻi loa no nā ʻano noi IR me nā ʻōnaehana laser CO2 mana kiʻekiʻe.
    ʻO Zinc Selenide ka haʻahaʻa IR absorption.He mea maikaʻi kēia no ke kiʻi wela, kahi e ʻike ʻia ai nā mahana o nā mea mamao ma o kā lākou ʻeleʻele radiation kino ʻeleʻele.He mea koʻikoʻi ka ʻikena hawewe lōʻihi no ke kiʻi ʻana i nā mea wela o ka lumi, e ʻā ana i ka lōʻihi haʻahaʻa ma kahi o 10 μm me ka haʻahaʻa haʻahaʻa.
    Loaʻa i ka ZnSe kahi papa kuhikuhi kiʻekiʻe o ka refraction e koi ana i kahi uhi anti-reflection e hoʻokō i ka hoʻouna kiʻekiʻe.Hoʻolālā ʻia kā mākou uhi ākea AR no 3 μm a 12 μm.
    ʻO nā mea Znse i hana ʻia e ka hoʻoheheʻe ʻana i ka mahu (CVD) ʻaʻole i loaʻa i ka hoʻomaʻemaʻe ʻana, haʻahaʻa loa ka pōʻino.Ma muli o ka haʻahaʻa haʻahaʻa haʻahaʻa loa no ka hawewe nalu 10.6um, no laila ʻo ZnSe ka mea koho mua no ka hana ʻana i nā mea optical o ka ʻōnaehana laser Co2 mana kiʻekiʻe.Eia kekahi, ʻo ZnSe kekahi ʻano mea maʻamau i hoʻohana ʻia no nā ʻōnaehana optical ʻokoʻa i ka holo ʻana i ka hawewe nalu holoʻokoʻa.
    Hana ʻia ʻo Zinc Selenide e ka synthesis mai ka Zinc vapor a me ke kinoea H2Se, i hana ʻia ma ke ʻano he pepa ma luna o nā susceptors Graphite.ʻO Zinc Selenide ka microcrystalline i loko o ka hoʻolālā, ke kāohi ʻia ka nui o ka palaoa e hana i ka ikaika kiʻekiʻe.Loaʻa ka ZnSe kristal hoʻokahi, akā ʻaʻole maʻamau akā ua hōʻike ʻia he haʻahaʻa ka absorption a no laila ʻoi aku ka maikaʻi no ka CO2 optics.

    ʻO Zinc Selenide ka hoʻohāhā nui ʻana ma 300°C, hōʻike i ka hoʻololi ʻana i ka plastic ma kahi o 500°C a hoʻokaʻawale ma kahi o 700°C.No ka palekana, ʻaʻole pono e hoʻohana ʻia nā puka makani Zinc Selenide ma luna o 250°C i ka lewa maʻamau.

    Nā noi:
    • Kūpono no nā noi laser CO2 mana kiʻekiʻe
    • 3 i ka 12 μm broadband IR antireflection uhi
    • ʻAʻole ʻōlelo ʻia nā mea palupalu no nā kaiapuni paʻakikī
    • Laser mana kiʻekiʻe a haʻahaʻa,
    • ʻōnaehana laser,
    • ʻepekema lapaʻau,
    • ka kilo hoku a me ka hihio IR i ka po.
    Nā hiʻohiʻona:
    • Poino hoopuehu haahaa.
    • Haʻahaʻa loa IR absorption
    • Kūleʻa loa i ka haʻalulu wela
    • Haʻahaʻa dispersion a haʻahaʻa absorption coefficient
