BaF2 Substrate txhais
BaF2 los yog barium fluoride yog cov khoom siv pob tshab crystalline feem ntau siv los ua cov substrate hauv ntau yam kev siv kho qhov muag.Nws belongs rau cov chav kawm ntawm inorganic tebchaw hu ua hlau halides thiab muaj zoo heev kho qhov muag thiab lub cev zog.
BaF2 substrates muaj ntau yam kis tau tus mob npog ultraviolet (UV) rau infrared (IR) wavelengths.Qhov no ua rau lawv haum rau ntau yam khoom siv kho qhov muag, suav nrog ultraviolet spectroscopy, imaging systems, optics rau qhov chaw-raws li telescopes thiab detector windows.
Ib qho ntawm cov yam ntxwv ntawm BaF2 substrate yog nws qhov siab refractive Performance index, uas ua rau kom muaj txiaj ntsig zoo ntawm lub teeb coupling thiab manipulation.Lub siab index ntawm refraction pab txo qhov kev xav tsis zoo thiab ua kom zoo dua qhov kev ua tau zoo ntawm cov txheej txheem kho qhov muag xws li cov coatings tiv thaiv kev cuam tshuam.
BaF2 kuj muaj kev tiv thaiv siab rau hluav taws xob puas tsuaj, ua rau nws zoo tagnrho rau cov ntawv thov nyob rau hauv high-zog hluav taws xob ib puag ncig, xws li particle physics thwmsim thiab nuclear tshuaj imaging.
Tsis tas li ntawd, BaF2 substrate muaj thermal stability zoo thiab tsis tshua muaj thermal expansion coefficient.Qhov no ua rau lawv tsim nyog rau kev siv nyob rau hauv qhov kub thiab txias ib puag ncig thiab kev siv uas yuav tsum tau ua haujlwm kho qhov muag kom tswj tau raws li qhov kub thiab txias.
Zuag qhia tag nrho, BaF2 substrates muaj qhov pom pom zoo tshaj plaws, qhov ntsuas siab tsis pom tseeb, tsis kam tiv thaiv hluav taws xob, thiab thermal stability, ua rau lawv muaj txiaj ntsig hauv ntau lub tshuab kho qhov muag thiab cov khoom siv.
