Gawo la CaF2
Kufotokozera
CaF2 Optical crystal ili ndi magwiridwe antchito abwino kwambiri a IR, omwe ali ndi zimango zamphamvu komanso Zopanda hygroscopic, Amagwiritsidwa ntchito kwambiri pawindo la kuwala.

CaF2 Substrate Tanthauzo
Gawo laling'ono la CaF2 limatanthawuza gawo laling'ono lopangidwa ndi makhiristo a calcium fluoride (CaF2).Ndi chinthu chowonekera chokhala ndi mawonekedwe abwino kwambiri owoneka bwino, monga kufalikira kwakukulu kumadera a ultraviolet (UV) ndi infrared (IR).Magawo a CaF2 amagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza makina owoneka bwino, owoneka bwino, fulorosenti, ndi makina a laser.Amapereka nsanja yokhazikika komanso yopanda mphamvu ya kukula kwa filimu yopyapyala, kuyika zokutira, komanso kupanga zida zowoneka bwino.Kuwonekera kwapamwamba komanso kutsika kwa refractive index ya CaF2 kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazinthu zowoneka bwino kwambiri monga magalasi, mazenera, ma prisms, ndi ma splitter amitengo.Kuphatikiza apo, magawo a CaF2 ali ndi kukhazikika kwamafuta komanso makina, kuwapangitsa kukhala abwino kwa malo ovuta komanso makina amphamvu kwambiri a laser.Ubwino wina wa gawo lapansi la CaF2 ndi index yake yotsika.Mlozera wocheperako wa refraction umathandizira kuchepetsa kutayika kwa zowunikira ndi zotsatira zosafunikira za kuwala, potero kumakulitsa magwiridwe antchito komanso chiŵerengero cha signal-to-noise cha optics ndi machitidwe.
Gawo laling'ono la CaF2 limakhalanso ndi kukhazikika kwamafuta komanso makina.Amatha kupirira kutentha kwambiri ndikuwonetsa kukana kwamphamvu kwa kutentha.Zinthu izi zimapangitsa magawo a CaF2 kukhala oyenera kugwiritsidwa ntchito m'malo ovuta, monga makina amphamvu kwambiri a laser, komwe kutayika kwa kutentha ndi kukhazikika ndikofunikira.
Kusakhazikika kwamankhwala kwa CaF2 kumaperekanso mwayi.Imalimbana ndi mankhwala osiyanasiyana ndi ma asidi, osavuta kugwira komanso ogwirizana ndi zinthu zosiyanasiyana komanso njira zopangira.
Ponseponse, kuphatikiza kwa mawonekedwe owoneka bwino, kukhazikika kwamafuta / makina, komanso kusakhazikika kwamankhwala kumapangitsa magawo a CaF2 kukhala abwino kwa mapulogalamu omwe amafunikira ma optics apamwamba kwambiri komanso odalirika.
