    Loaʻa i ka Calcium Fluoride ka noi IR ākea e like me nā puka aniani CaF2 spectroscopic, nā prisms CaF2 a me nā lens CaF2.Loaʻa nā māka maʻemaʻe o ka Calcium Fluoride (CaF2) i ka noi kūpono i ka UV a me nā puka makani laser Excimer UV.Loaʻa ka Calcium Fluoride (CaF2) doped me Europium ma ke ʻano he scintillator gamma-ray a ʻoi aku ka paʻakikī ma mua o ka Barium Fluoride.
    Hiki ke hoʻohana ʻia ka Calcium Fluoride no nā noi he nui, me ka vacuum ultra violet, ultra violet a me ka infrared thermal imaging.Hoʻohana maʻamau ka calcium fluoride i ka hoʻolālā apochromatic e hōʻemi i ka hoʻopuehu māmā ʻana i nā lens, ma nā kāmera a me nā telescopes, a ua hoʻohana ʻia i ka ʻoihana aila a me ke kinoea ma ke ʻano he ʻāpana i nā detectors a me nā spectrometers.Hoʻohana mua ʻia i nā puka aniani spectroscopic, a me nā kiʻi wela a me nā ʻōnaehana ʻē aʻe kahi e koi ʻia ai ka hoʻoili kiʻekiʻe ma waena o 0.2µm a me 8µm, ua hoʻouka ʻia ka fluoride calcium e nā reagents liʻiliʻi a hāʻawi i kahi coefficient absorption haʻahaʻa a me ka paepae pōʻino kiʻekiʻe, pono i kāna hoʻohana ʻana i excimer. ʻōnaehana laser.
    Hoʻohana ʻia ʻo Calcium Fluoride i nā ʻōnaehana spectroscopy no ka hoʻokele ʻana a me ka nānā ʻana.Hāʻawi nā lens CaF2 a me nā puka makani ma luna o 90% ka hoʻouna ʻana mai 350nm a hiki i 7µm a hoʻohana ʻia i nā ʻōnaehana spectrometer kahi e koi ʻia ai kahi ākea ākea ākea.Hiki i ka Calcium Fluoride ke hoʻohana ʻia i nā ʻōnaehana me ka ʻole o ka hoʻohana ʻana i nā pale antireflection, ʻaʻole like me nā mea IR ʻē aʻe.
