Ngoku ekubeni ukwazi ukubala ukuba yeyiphi idosi oyifumanayo, kufuneka wazi ukuba yeyiphi idosi esebenzayo ngokwenene. Uninzi lwamanqaku ophononongo kunye nezixhobo zemfundo zidla ngokuthi idosi ephakathi kwe-0.1J/cm² ukuya kwi-6J/cm² yeyona ifanelekileyo kwiiseli, ngaphandle kokwenza nto ingako kwaye okuninzi kurhoxisa izibonelelo.
Nangona kunjalo, ezinye izifundo zifumana iziphumo ezilungileyo kwiindawo eziphezulu kakhulu, ezifana ne-20J/cm², 70J/cm², kwaye zide zibe phezulu njenge-700J/cm². Kusenokwenzeka ukuba isiphumo esinzulu senkqubo yomzimba sibonakala kwiidosi eziphezulu, kuxhomekeke ekubeni ingakanani amandla asetyenziswa emzimbeni iyonke. Kusenokwenzeka nokuba idosi ephezulu iyasebenza kuba ukukhanya kungena nzulu. Ukufumana idosi ye-1J/cm² kumaleko ophezulu wesikhumba kuya kuthatha imizuzwana embalwa kuphela. Ukufumana idosi ye-1J/cm² kwizicubu ezinzulu zemisipha kunokuthatha ixesha elide eliphindwe kayi-1000, kufuna i-1000J/cm²+ kulusu olungaphezulu.
Umgama womthombo wokukhanya ubaluleke kakhulu apha, njengoko kumisela ubungakanani bamandla okukhanya afikelela eluswini. Umzekelo, ukusebenzisa isixhobo sokukhanya okuBomvu kwi-25cm endaweni ye-10cm kuya kwandisa ixesha lokufaka elifunekayo kodwa kugqume indawo enkulu yesikhumba. Akukho nto imbi ngokuyisebenzisa usuka kude, qiniseka ukuba uyayilungisa ngokwandisa ixesha lokufaka.
Ukubala ukuba iseshoni ithatha ixesha elingakanani
Ngoku kufuneka wazi ubuninzi bamandla okukhanya kwakho (buyahluka ngokomgama) kunye nomthamo owufunayo. Sebenzisa le fomyula ingezantsi ukubala ukuba zingaphi imizuzwana ekufuneka usebenzise isibane sakho kuyo:
Ixesha = Idosi ÷ (Ubuninzi bamandla x 0.001)
Ixesha ngemizuzwana, idosi kwi-J/cm² kunye noxinano lwamandla kwi-mW/cm²
