BaF2 Substrate Definition
I-BaF2 okanye i-barium fluoride yimathiriyeli yekristale ebonakalayo edla ngokusetyenziswa njenge-substrate kwizicelo ezahlukeneyo zamehlo.Yeyodidi lwe-inorganic compounds eyaziwa ngokuba yi-metal halides kwaye ineempawu ezibalaseleyo zokubona kunye nezomzimba.
I-BaF2 substrates inoluhlu olubanzi lothumelo olugubungela i-ultraviolet (UV) ukuya kwi-infrared (IR) wavelengths.Oku kubenza bafanelekele uluhlu lwezixhobo ezibonakalayo, kubandakanywa i-spectroscopy ye-ultraviolet, iinkqubo zokucinga, i-optics ye-telescopes ezisekelwe kwindawo kunye neefestile ze-detector.
Enye yeempawu eziphawulekayo ze-BaF2 substrate yi-index yayo ephezulu ye-refractive, eyenza ukudibanisa ukukhanya okusebenzayo kunye nokukhwabanisa.Isalathiso esiphezulu se-refraction sinceda ukunciphisa ilahleko yokubonakalisa kunye nokwandisa ukusebenza kweengubo ze-optical ezifana ne-anti-reflective coatings.
I-BaF2 ikwanayo nokumelana okuphezulu nomonakalo wokusasazeka kwemitha, iyenza ilungele ukusetyenziswa kwindawo ene-eneji yemitha ephezulu, efana nemifuniselo yefiziksi yamasuntswana kunye nokucinga ngamayeza enyukliya.
Ukongeza, i-substrate ye-BaF2 inozinzo oluhle lwe-thermal kunye ne-coefficient yokwandisa i-thermal ephantsi.Oku kubenza bafaneleke ukusetyenziswa kwiindawo eziphezulu zokushisa kunye nezicelo ezifuna ukusebenza kwe-optical ukuba kugcinwe phantsi kweemeko zokushisa ezahlukeneyo.
Ngokubanzi, ii-substrates ze-BaF2 zine-optical transparency egqwesileyo, isalathisi esiphezulu se-refractive, ukuchasana nomonakalo we-radiation, kunye nokuzinza kwe-thermal, okubenza baxabiseke kwiinkqubo ezahlukeneyo ze-optical kunye nezixhobo.
