Fluorescent number case ua nrog cov xim fluorescent uas muaj cov cuab yeej ntawm kev hloov lub wavelengths luv luv ntawm lub teeb ultraviolet mus rau lub teeb pom ntev dua kom pom cov xim ntau dua.
Fluorescent number case yog ultraviolet fluorescent number case, tseem hu ua xim tsis muaj xim fluorescent ink thiab invisible ink, yog tsim los ntawm kev ntxiv cov khoom sib txuam pom fluorescent hauv tus number case.
Daim ntawv thov ntawm lub teeb ultraviolet (200-400nm) irradiation excitation thiab emit pom lub teeb (400-800nm) tshwj xeeb number case, hu ua UV fluorescent number case.
Nws tuaj yeem muab faib ua nthwv dej luv luv thiab ntev nthwv dej raws li qhov sib txawv excitation wavelength.
Lub excitation wavelength ntawm 254nm yog hu ua luv-yoj UV fluorescent number case, lub excitation wavelength ntawm 365nm yog hu ua long-wave UV fluorescent number case, raws li kev hloov xim thiab muab faib ua xim tsis muaj xim, tsis muaj xim, discoloration peb, tsis muaj xim tuaj yeem pom liab, daj. , ntsuab, xiav thiab daj xim;
Xim tuaj yeem ua rau cov xim qub ci;
Kev hloov xim tuaj yeem hloov ib xim mus rau lwm qhov.
