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 kwiimpawu 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.
