ʻO ka wehewehe ʻana o ka substrate BaF2
ʻO ka BaF2 a i ʻole ka barium fluoride kahi mea aniani aniani i hoʻohana mau ʻia ma ke ʻano he substrate i nā noi optical like ʻole.Aia ia i ka papa o nā pūhui inorganic i ʻike ʻia ʻo nā halides metala a loaʻa iā ia nā waiwai optical a me ke kino.
Loaʻa i nā substrates BaF2 kahi laula hoʻouna ākea e uhi ana i nā lōʻihi hawewe ultraviolet (UV) a i ka infrared (IR).ʻO kēia ka mea i kūpono iā lākou no ka nui o nā mea uila, me ka spectroscopy ultraviolet, nā ʻōnaehana kiʻi kiʻi, nā optics no nā telescopes a me nā puka makani ʻike.
ʻO kekahi o nā hiʻohiʻona ʻokoʻa o ka substrate BaF2 ʻo ia kona kiʻekiʻe refractive index, e hiki ai i ka hoʻopili māmā a me ka hoʻoponopono ʻana.ʻO ka helu helu kiʻekiʻe o ka refraction e kōkua i ka hōʻemi ʻana i ka nalowale o ka noʻonoʻo ʻana a me ka hoʻokō ʻana i ka hana o nā uhi ʻike e like me nā uhi anti-reflective.
He kūpaʻa kiʻekiʻe nō hoʻi ʻo BaF2 i ka pōʻino o ka radiation, e kūpono ana ia no nā noi ma nā wahi hoʻoheheʻe ikaika nui, e like me nā hoʻokolohua ʻokoʻa physics a me ke kiʻi lāʻau nuklea.
Eia kekahi, ʻo ka substrate BaF2 he paʻa wela maikaʻi a haʻahaʻa haʻahaʻa hoʻonui hoʻonui.ʻO kēia ka mea i kūpono iā lākou no ka hoʻohana ʻana i nā wahi wela kiʻekiʻe a me nā noi e koi ana i ka hana optical e mālama ʻia ma lalo o nā kūlana wela.
Ma ke ʻano holoʻokoʻa, loaʻa i nā substrates BaF2 ka ʻike ʻike maikaʻi loa, ka helu refractive kiʻekiʻe, ke kūpaʻa ʻana i ka pōʻino o ka radiation, a me ke kūpaʻa wela, e hoʻolilo iā lākou i mea waiwai i nā ʻōnaehana optical a me nā mea hana.
