Gawo la BaF2
Kufotokozera
BaF2 Optical crystal ili ndi magwiridwe antchito abwino kwambiri a IR, kutulutsa kwabwino kwa mawonekedwe osiyanasiyana.

Tanthauzo la gawo lapansi la BaF2
BaF2 kapena barium fluoride ndi zinthu zowoneka bwino za crystalline zomwe zimagwiritsidwa ntchito ngati gawo lapansi pazogwiritsa ntchito zosiyanasiyana.Ndi m'gulu la mankhwala opangidwa ndi inorganic otchedwa metal halides ndipo ali ndi mawonekedwe owoneka bwino komanso owoneka bwino.
Magawo a BaF2 ali ndi mitundu yotakata yopatsirana yomwe imaphimba mafunde a ultraviolet (UV) kupita ku infrared (IR) wavelengths.Izi zimawapangitsa kukhala oyenerera pazida zosiyanasiyana zowoneka bwino, kuphatikiza ma ultraviolet spectroscopy, makina ojambulira, ma optics a ma telescope otengera malo ndi mazenera owunikira.
Chimodzi mwazinthu zosiyanitsa gawo la gawo la BaF2 ndi index yake yayikulu ya refractive, yomwe imathandizira kulumikizana bwino kwa kuwala ndikusintha.Mlozera wapamwamba wa refraction umathandizira kuchepetsa kutayika kwa zowunikira ndikuwongolera magwiridwe antchito a zokutira zowoneka bwino monga zokutira zotsutsana ndi reflective.
BaF2 ilinso ndi kukana kwambiri kuwonongeka kwa ma radiation, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo okhala ndi mphamvu zambiri, monga kuyesa kwa particle physics ndi kulingalira kwamankhwala a nyukiliya.
Kuphatikiza apo, gawo laling'ono la BaF2 lili ndi kukhazikika kwabwino kwamafuta komanso kutsika kwamphamvu kowonjezera kwamafuta.Izi zimawapangitsa kukhala oyenera kugwiritsidwa ntchito m'malo otentha kwambiri komanso ntchito zomwe zimafuna kuti mawonekedwe aziwoneka bwino azisungidwa mosiyanasiyana kutentha.
Ponseponse, magawo a BaF2 ali ndi mawonekedwe owoneka bwino kwambiri, mawonekedwe apamwamba a refractive, kukana kuwonongeka kwa ma radiation, komanso kukhazikika kwamafuta, kuwapangitsa kukhala ofunikira pamakina ndi zida zosiyanasiyana.
