Calcium Fluoride (CaF2)
Calcium Fluoride (CaF2) bụ otu kristal cubic, ọ na-arụ ọrụ na gburugburu ebe obibi.CaF2a na-ejikarị maka ngwa chọrọ nnyefe dị elu na oke infrared na ultraviolet spectral ranges.Ngwa ahụ na-egosiputa akara ntugharị dị ala, dị iche site na 1.35 ruo 1.51 n'ime oke ojiji ya nke 180 nm ruo 8.0 μm, ọ nwere ntugharị refractive nke 1.428 na 1.064 µm.Calcium fluoride bụkwa nke na-adịghị ahụkebe nke ọma ma na-enye ike dị elu ma e jiri ya tụnyere barium fluoride, magnesium fluoride, na nwanne nwanne ya nke lithium fluoride.Agbanyeghị, CaF2bụ ntakịrị hygroscopic ma nwee ike ịdaba na ujo ọkụ.Calcium Fluoride dị mma maka ngwa ọ bụla na-achọsi ike ebe oke mmebi ya dị elu, obere fluorescence, na ịdị n'otu dị elu bara uru.Ọnụ ụzọ mmebi laser dị oke elu na-eme ka a na-eji ya na ngwa laser excimer, a na-ejikarị ya na spectroscopy na eserese okpomọkụ dị jụụ.
