He kupu whakataki poto mōNgongo whakaahua ultraviolet:

Ko te ngongo whakaahua ultraviolet he momo ngongo kimi ultraviolet me te pānga photoelectric. Ka whakamahia e tēnei momo pūtau whakaahua te cathode hei whakaputa tukunga whakaahua, ka neke ngā irahiko photoelectron ki te anode i raro i te mahi a te mara hiko, ā, ka puta te ionization nā te tukinga ki ngā ngota hau i roto i te ngongo i te wā o te ionization; ka whiwhi te anode i ngā irahiko hou me ngā irahiko photoelectron i hangaia e te tukanga ionization, ko ngā ion pai ka whiwhi te cathode i te taha ke. Nō reira, he maha ngā wā ka nui ake te iahiko photoelectric i roto i te ara iahiko anode i tērā i roto i te ngongo whakaahua korehau. Ka taea e ngā pūtau whakaahua ultraviolet me ngā pānga photovoltaic whakarewa me te hau te kite i te irahiko ultraviolet i roto i te awhe 185-300mm me te whakaputa i te iahiko photoelectric.

Kāore e pāngia e te hihi i waho o tēnei rohe hihi, pērā i te hihi o te rā e kitea ana me ngā pūtake rama o roto. Nō reira, kāore e hiahiatia te whakamahi i te pare rama e kitea ana pērā i ētahi atu taputapu haurua-ā-ira, nō reira he watea ake te whakamahi.
Ka taea e te ngongo whakaahua ultraviolet te kite i te ngoikore o te hihi ultraviolet. Ka taea te whakamahi i roto i te hinu wahie poiha, te aroturuki hau, te whakaoho ahi, te pūnaha hiko hei aroturuki i te tiaki uira o te whakawhiti hiko kāore e tiakina, me ētahi atu.
