Ukhetho olwahlukileyo lwesibane segumbi lovavanyo lokuguga le-ultraviolet (UV)
Ukulinganisa i-ultraviolet kunye nelanga
Nangona ukukhanya kwe-ultraviolet (UV) kubangela i-5% kuphela yelanga, yeyona nto iphambili ebangela ukuba ukuqina kweemveliso zangaphandle kwehle. Oku kungenxa yokuba impembelelo ye-photochemical yelanga iyanda ngokuncipha kwe-wavelength.
Ngoko ke, akunyanzelekanga ukuphinda uvelise lonke uhlobo lokukhanya kwelanga xa ulinganisa impembelelo eyonakalisayo yokukhanya kwelanga kwiimpawu ezibonakalayo zezinto. Kwiimeko ezininzi, kufuneka silinganise ukukhanya kwe-UV kwegagasi elifutshane.
Isizathu sokuba izibane ze-UV zisetyenziswe kwigumbi lovavanyo lokuguga lwe-UV kukuba zizinzile ngakumbi kunezinye izibane kwaye zinokuvelisa iziphumo zovavanyo ngcono. Ukusebenzisa isibane se-UV esikhanyayo ukulinganisa impembelelo yokukhanya kwelanga kwiimpawu zomzimba, ezinje ngokuncipha kokukhanya, ukuqhekeka, ukuxobuka, njalo njalo, yeyona ndlela ilungileyo.
Kukho izibane ezahlukeneyo ze-UV onokukhetha kuzo. Uninzi lwezi zibane ze-UV zivelisa ukukhanya kwe-ultraviolet endaweni yokukhanya okubonakalayo kunye nokukhanya kwe-infrared. Umahluko ophambili wezibane ubonakala kumandla e-UV apheleleyo aveliswa zizo kuluhlu lwazo lwamaza ombane.
Izibane ezahlukeneyo ezisetyenziswa kwigumbi lovavanyo lokuguga le-ultraviolet ziya kuvelisa iziphumo zovavanyo ezahlukeneyo. Indawo yokusetyenziswa kokukhanya inokubonisa ukuba loluphi uhlobo lwesibane se-UV ekufuneka sikhethwe. Iingenelo zezibane ze-fluorescent ziziphumo zovavanyo ezikhawulezayo; ulawulo lokukhanyisa olulula; i-spectrum ezinzileyo; ulondolozo oluncinci; ixabiso eliphantsi kunye neendleko zokusebenza ezifanelekileyo.
