Ukhetho olwahlukileyo lwesibane segumbi lokuvavanya ukuguga kwe-ultraviolet (UV).
Ukulinganisa i-ultraviolet kunye nokukhanya kwelanga
Nangona ukukhanya kwe-ultraviolet (UV) kubala kuphela i-5% yokukhanya kwelanga, yeyona nto iphambili yokukhanyisa eyenza ukuqina kweemveliso zangaphandle kwehle. Oku kungenxa yokuba impembelelo yefotochemical yokukhanya kwelanga yonyuka ngokuhla kwe-wavelength.
Ngoko ke, akuyimfuneko ukuvelisa i-spectrum yokukhanya kwelanga xa ulinganisa umphumo owonakalisayo wokukhanya kwelanga kwiipropati ezibonakalayo zezinto eziphathekayo. Kwiimeko ezininzi, sifuna kuphela ukulinganisa isibane se-UV samaza amafutshane.
Isizathu sokuba izibane ze-UV zisetyenziswe kwigumbi lovavanyo lokuguga le-UV kukuba zizinzile kunezinye izibane kwaye zinokuvelisa iziphumo zovavanyo ngcono. Ukusebenzisa isibane se-UV se-fluorescent ukulinganisa impembelelo yokukhanya kwelanga kwiipropati ezibonakalayo, ezifana nokuncipha kokukhanya, ukuqhekeka, ukuxobula, njalo njalo, yeyona ndlela ilungileyo.
Kukho izibane ezahlukeneyo ze-UV onokukhetha kuzo. Uninzi lwezi zibane ze-UV zivelisa ukukhanya kwe-ultraviolet kunokukhanya okubonakalayo kunye ne-infrared. Umahluko omkhulu wezibane ubonakaliswa kumandla e-UV ewonke aveliswa ngabo kuluhlu lwamaza ahlukeneyo.
Izibane ezahlukeneyo ezisetyenziswa kwigumbi lokuvavanya ukuguga kwe-ultraviolet ziya kuvelisa iziphumo ezahlukeneyo zovavanyo. Eyona ndawo ingqongileyo yesicelo sokuvezwa inokwazisa ukuba loluphi uhlobo lwesibane se-UV ekufuneka sikhethwe. Iingenelo zezibane ze-fluorescent ziziphumo zovavanyo olukhawulezayo; ulawulo lokhanyiso olwenziwe lula; i-spectrum ezinzileyo; isondlo esincinci; ixabiso eliphantsi kunye neendleko ezifanelekileyo zokusebenza.
