Intshayelelo emfutshane yeItyhubhu yefoto ye-Ultraviolet:

I-Ultraviolet phototube luhlobo lwetyhubhu yokubona i-ultraviolet enefuthe le-photoelectric. Olu hlobo lwe-photocell lusebenzisa i-cathode ukuvelisa i-photoemission, ii-photoelectrons ziya kwi-anode phantsi kwesenzo sentsimi yombane, kwaye i-ionization yenzeka ngenxa yokungqubana neeathom zegesi kwityhubhu ngexesha le-ionization; ii-electron ezintsha kunye nee-photoelectron ezenziwe yinkqubo ye-ionization zombini zifunyanwa yi-anode, ngelixa ii-ions ezintle zifunyanwa yi-cathode kwicala elichaseneyo. Ke ngoko, i-photocurrent kwisekethe ye-anode inkulu ngokuphindwe kaninzi kunaleyo ikwi-vacuum phototube. Ii-photocell ze-Ultraviolet ezine-photovoltaic yesinyithi kunye neziphumo ze-gas multiplier zinokubona imitha ye-ultraviolet kuluhlu lwe-185-300mm kwaye zivelise i-photocurrent.

Ayinamvakalelo kwimitha engaphandle kwale ndawo ye-spectral, njengokukhanya kwelanga okubonakalayo kunye nemithombo yokukhanya yangaphakathi. Ngoko ke akufuneki ukusebenzisa isikhuselo sokukhanya esibonakalayo njengezinye izixhobo ze-semiconductor, ngoko ke kulula ngakumbi ukuyisebenzisa.
I-ultraviolet phototube inokubhaqa imitha ye-ultraviolet ebuthathaka. Ingasetyenziswa kwi-oyile ye-fuel yebhoyila, ukujonga igesi, i-alamu yomlilo, inkqubo yamandla yokujonga umbane kwi-transformer engajongwanga, njl.
