    Khetho le Tšebeliso ea Radiometer ea UV

    新闻缩略图 5-24

    Ho na le lintlha tse 'maloa tse lokelang ho nahanoa ha u khetha sesebelisoa sa mahlaseli a UV. Tsena li kenyelletsa boholo ba sesebelisoa le sebaka se fumanehang, hammoho le ho netefatsa hore karabo ea sesebelisoa e ntlafalitsoe bakeng sa lebone la UV le lekoang. Ke habohlokoa ho hlokomela hore li-radiometer tse etselitsoeng mehloli ea leseli la mercury li ka 'na tsa se ke tsa tšoanelehaMehloli ea leseli la UV LED, kahoo ke cirtical ho buisana le baetsi ba lisebelisoa ho etsa bonnete ba ho lumellana.

    Li-radiometer li sebelisa mekhoa e fapaneng ea ho arabela, 'me bophara ba karabelo ea sehlopha ka seng bo khethoa ke moetsi oa lisebelisoa. Ho fumana 'malo o nepahetseng oa LED, ho khothalletsoa ho sebelisa radiometer e nang le karabo e bataletseng ka har'a ± 5 nm CWL ea thahasello. Li-waveband tse tšesaane li ka fumana likarabo tse bataletseng tsa mahlo. Ho feta moo, ho bohlokoa ho lekanya radiometer ho sebelisa mohloli o tšoanang oa radiation joalo ka o lekantsoeng ho ntlafatsa ts'ebetso ea ona. Mefuta e matla ea sesebelisoa e boetse e lokela ho nkoa ho netefatsa hore e loketse ho lekanya LED e khethehileng. Ho sebelisa li-radiometer tse ntlafalitsoeng bakeng sa mehloli ea matla a tlase kapa li-LED tse nang le matla a phahameng ho ka fella ka ho bala ho sa nepahalang ho fetang sebaka sa sesebelisoa.

    Le hoja li-LED tsa UV li hlahisa mocheso o fokolang ho feta mekhoa e thehiloeng ho mercury, li ntse li hlahisa mocheso o itseng. Ka hona, ke habohlokoa ho shebella mocheso oa radiometer nakong ea ho pepeseha ha LED e tsitsitseng le ho netefatsa hore e lula e le ka har'a meeli e khothalletsoang. Ho khothalletsoa hore radiometer e lumelloe ho pholile pakeng tsa litekanyo. E le molao o akaretsang oa monoana, haeba radiometer e chesa haholo hore e se ke ea ama, e chesa haholo ho etsa litekanyo tse nepahetseng. Ho feta moo, ho beha lisebelisoa tsa optics libakeng tse fapaneng ka tlas'a lebone la UV LED ho ka baka phapang e fokolang ha ho baloa, haholo-holo haeba li le haufi le fensetere ea quartz.Sistimi ea UV ea LED. Mekhoa e tsitsitseng ea ho bokella lintlha e bohlokoa bakeng sa ho fumana liphetho tse tšepahalang.

    Qetellong, basebelisi ba lokela ho latela litataiso tsa moetsi bakeng sa tšebeliso e nepahetseng, tlhokomelo le tlhoekiso ea sesebelisoa. Ho lekanya khafetsa le ho lokisoa ha li-radiometer hoa hlokahala ho boloka ho nepahala ha tsona.
