ʻO CaF2 optical crystal he hana IR maikaʻi loa, nona ka strangth mechanics a me Non-hygroscopic, Hoʻohana nui ia no ka puka aniani.

ʻO ka wehewehe ʻana o ka substrate CaF2
ʻO ka substrate CaF2 e pili ana i kahi mea pani i haku ʻia me nā kristal calcium fluoride (CaF2).He mea akaka ia me nā waiwai optical maikaʻi loa, e like me ka transmittance kiʻekiʻe ma nā ʻāpana ultraviolet (UV) a me infrared (IR).Hoʻohana maʻamau ʻia nā substrates CaF2 i nā ʻano noi like ʻole, me ka optical, spectroscopic, fluorescent, a me nā ʻōnaehana laser.Hāʻawi lākou i kahi kahua paʻa a inert no ka ulu ʻana o nā kiʻiʻoniʻoni lahilahi, ka waiho ʻana o ka uhi, a me ka hana ʻana i nā mea hana optical.ʻO ka ʻike kiʻekiʻe a me ka helu refractive haʻahaʻa o CaF2 e kūpono ia no ka hoʻohana ʻana i nā ʻāpana optical kiʻekiʻe e like me nā lens, windows, prisms, a me nā mea hoʻokaʻawale beam.Eia hou, ua loaʻa i nā substrates CaF2 maikaʻi ka thermal a me ka mechanical stability, e hoʻolilo iā lākou i mea kūpono no nā kaiapuni paʻakikī a me nā ʻōnaehana laser kiʻekiʻe.ʻO kekahi pōmaikaʻi ʻē aʻe o ka substrate CaF2 ʻo ia ka haʻahaʻa refractive index.ʻO ka helu haʻahaʻa o ka refraction e kōkua i ka hōʻemi ʻana i nā poho noʻonoʻo a me nā hopena optical makemake ʻole, ma laila e hoʻonui ai i ka hana optical a me ka ratio signal-to-noise o nā optics a me nā ʻōnaehana.
Loaʻa i ka substrate CaF2 kahi paʻa wela a me ka mechanical maikaʻi.Hiki iā lākou ke kū i nā wela kiʻekiʻe a hōʻike i ke kūpaʻa haʻalulu maikaʻi loa.Hoʻohana kēia mau waiwai i nā substrates CaF2 i kūpono no ka hoʻohana ʻana i nā kaiapuni koi, e like me nā ʻōnaehana laser mana kiʻekiʻe, kahi mea koʻikoʻi ka wela a me ka lōʻihi.
ʻO ka inertness kemika o CaF2 e hāʻawi iā ia i mea pono.He kūpaʻa ia i ka nui o nā kemika a me nā waikawa, maʻalahi e mālama a kūpono me nā ʻano mea like ʻole a me nā kaʻina hana.
Ma keʻano holoʻokoʻa, ʻo ka hui pū ʻana o nā waiwai optical maikaʻi loa, ke kūpaʻa wela/mechanical, a me ka inertness kemika e kūpono i nā substrates CaF2 no nā noi e koi ana i nā optics kiʻekiʻe a me ka hilinaʻi.
