Ezimweni zemvelo, imisebe yelanga ibhekwa njengesizathu esiyinhloko sokuguga, futhi isimiso sokuchayeka emisebeni ngaphansi kwengilazi yefasitela siyafana.Ngakho-ke, ukulingisa imisebe yelanga kubalulekile ekugugeni kwesimo sezulu sokwenziwa kanye nokuchayeka okwenziwe emisebeni.Umthombo wemisebe ye-xenon arc uthola enye yezinhlelo ezimbili ezihlukene zokuhlunga ukukhanya ukuze uguqule ukusatshalaliswa kwe-spectral kwemisebe eyikhiqizayo, ukulingisa ukusatshalaliswa okubonakalayo kwemisebe yelanga e-ultraviolet nebonakalayo, futhi kulingisa ukusatshalaliswa okubonakalayo kwemisebe ye-ultraviolet nemisebe yelanga ebonakalayo ehlungwe nge-3mm. ingilazi yefasitela eliwugqinsi.

Ukusatshalaliswa kwamandla kwe-spectra emibili kuchaza inani le-irradiance kanye nokuchezuka okuvumelekile kwemisebe yokukhanya ehlungwa yisihlungi ebangeni lokukhanya kwe-ultraviolet elingaphansi kwamaza angama-400mm.Ngaphezu kwalokho, i-CIE No.85 inendinganiso ye-irradiance enobude obungafika ku-800nm, njengoba imisebe ye-xenon arc ingalingisa kangcono imisebe yelanga ngaphakathi kwalolu hlu.

Ngesikhathi sokuhlolwa kwemishini yokuchayeka, i-irradiance ingashintsha ngenxa yokuguga kwe-xenon arc kanye nohlelo lokuhlunga.Lolu shintsho lwenzeka ikakhulukazi ebangeni le-ultraviolet, elinomthelela omkhulu we-photochemical ezintweni ze-polymer.Ngakho-ke, akudingekile kuphela ukulinganisa isikhathi sokuchayeka, kodwa futhi ukukala ububanzi be-wavelength obungaphansi kuka-400nm noma amandla emisebe yokuchayeka kubude obucacisiwe obunjengo-340nm, futhi usebenzise lawa manani njengamavelu ereferensi wokuguga.

Akunakwenzeka ukulingisa ngokunembile imiphumela yezici ezihlukahlukene zezimo zezulu ezimbotsheni.Ngakho-ke, ezingeni legumbi lokuhlola isibani se-xenon, igama elithi ukuguga kwesimo sezulu sokwenziwa lisetshenziselwa ukuhlukanisa ukuguga kwesimo sezulu semvelo.Ukuhlola okulingisiwe kwengilazi yefasitela ehlungiwe ngemisebe yelanga okukhulunywe ngayo esilinganisweni segumbi lokuhlola isibani se-xenon kubizwa ngokuthi ukuchayeka emisebeni yokwenziwa.
