Qeexitaan Substrate BaF2
BaF2 ama barium fluoride waa walax crystalline hufan oo caadi ahaan loo isticmaalo sida substrate ee codsiyada kala duwan ee indhaha.Waxay ka tirsan tahay fasalka xeryahooda inorganic ee loo yaqaan halides birta waxayna leedahay sifooyin muuqaal iyo muuqaal aad u wanaagsan.
Substrates BaF2 waxay leeyihiin fidin ballaaran oo daboolaya ultraviolet (UV) ilaa mowjadaha dhererka infrared (IR).Tani waxay ka dhigaysaa inay ku habboon yihiin qalabyo kala duwan oo indho-indhayn ah, oo ay ku jiraan ultraviolet spectroscopy, hababka sawir-qaadista, indho-fiiqyada telescopes-ku-salaysan iyo daaqadaha wax baadha.
Mid ka mid ah astaamaha lagu garto substrate-ka BaF2 ayaa ah tusmihiisa sare u kaca, kaas oo awood u siinaya isku xidhka iftiinka iyo wax-is-dabamarinta.Tusmada sare ee dib-u-celinta waxay ka caawisaa in la yareeyo khasaaraha milicsiga iyo wanaajinta waxqabadka dahaarka indhaha sida dahaarka ka-hortagga milicsiga.
BaF2 sidoo kale waxay leedahay iska caabin sare oo waxyeello shucaac ah, taasoo ka dhigaysa mid ku habboon codsiyada jawiga shucaaca tamarta sare leh, sida tijaabooyinka fiisigiska qaybaha iyo sawirka daawada nukliyeerka.
Intaa waxaa dheer, substrate BaF2 wuxuu leeyahay degganaansho kulayl wanaagsan iyo iskudubarid kuleyl oo hooseeya.Tani waxay ka dhigaysaa inay ku habboon yihiin isticmaalka jawiga heerkulka sare iyo codsiyada u baahan waxqabadka indhaha si loogu ilaaliyo xaaladaha heerkulka kala duwan.
Guud ahaan, BaF2 substrates waxay leeyihiin hufnaan muuqaal ah oo heer sare ah, index refractive sare, caabbinta waxyeellada shucaaca, iyo xasiloonida kulaylka, taas oo ka dhigaysa mid qiimo leh hababka iyo qalabka kala duwan ee indhaha.
