CaF2 Substrate txhais
CaF2 substrate yog hais txog cov khoom siv substrate uas muaj calcium fluoride (CaF2) crystals.Nws yog cov khoom siv pob tshab nrog cov khoom siv kho qhov muag zoo, xws li kev xa tawm siab hauv cheeb tsam ultraviolet (UV) thiab infrared (IR).CaF2 substrates feem ntau yog siv rau ntau yam kev siv, suav nrog kho qhov muag, spectroscopic, fluorescent, thiab laser tshuab.Lawv muab lub platform ruaj khov thiab inert rau nyias zaj duab xis loj hlob, txheej deposition, thiab kho qhov muag khoom fabrication.Lub siab transparency thiab qis refractive index ntawm CaF2 ua rau nws haum rau siv nyob rau hauv high-precision optical Cheebtsam xws li lo ntsiab muag, qhov rais, prisms, thiab beam splitters.Tsis tas li ntawd, CaF2 substrates muaj qhov zoo thermal thiab mechanical stability, ua rau lawv zoo tagnrho rau ib puag ncig hnyav thiab lub zog laser tshuab.Lwm qhov zoo ntawm CaF2 substrate yog nws qhov qis qis qis.Qhov ntsuas qis ntawm refraction pab txo qhov kev xav tsis zoo thiab tsis xav tau qhov cuam tshuam ntawm qhov muag, yog li txhim kho qhov kev ua tau zoo ntawm qhov muag thiab cov teeb liab-rau- suab nrov piv ntawm optics thiab tshuab.
Lub CaF2 substrate kuj muaj thermal thiab mechanical stability.Lawv tuaj yeem tiv taus qhov kub thiab txias thiab pom zoo thermal shock tsis kam.Cov khoom no ua rau CaF2 substrates tsim nyog siv rau hauv qhov xav tau ib puag ncig, xws li lub zog laser tshuab, qhov kub dissipation thiab durability yog qhov tseem ceeb.
Cov tshuaj inertness ntawm CaF2 kuj ua rau nws zoo dua.Nws yog resistant rau ntau yam tshuaj thiab acids, yooj yim los lis thiab sib xws nrog ntau yam ntaub ntawv thiab kev tsim khoom.
Zuag qhia tag nrho, kev sib xyaw ua ke ntawm cov khoom siv kho qhov muag zoo heev, thermal / mechanical stability, thiab tshuaj inertness ua rau CaF2 substrates zoo tagnrho rau cov ntawv thov uas xav tau qhov zoo tshaj plaws optics thiab kev ntseeg siab.
