1. Mabda'a ogaanshaha gudbinta ee UV lens
Cabbirka gudbinta muraayadaha muraayadaha looma farsamayn karo celcelis fudud oo ah gudbinta spectral ee hirarka dhererka kasta, laakiin waa in lagu helaa is dhexgalka miisaanka ee gudbinta spectral iyadoo loo eegayo culeyska hirarka dhaadheer ee kala duwan.Isha bini'aadamku waa hab fudud oo indhaha ah.Marka la qiimeeyo tayada muraayadaha, dareenka isha bini'aadamka ee shucaaca iftiinka ee hirarka kala duwan waa in marka hore la tixgeliyaa.Marka la soo koobo, isha bini'aadamku waxay u nugul yihiin iftiinka cagaaran, sidaas darteed gudbinta xargaha iftiinka cagaaran ayaa saameyn weyn ku leh gudbinta iftiinka muraayadda, taas oo ah, miisaanka xargaha iftiinka cagaaran ayaa ka weyn;taa caksigeeda, sababtoo ah isha bini'aadamku uma nugula iftiinka guduudan iyo casaanka, sidaas darteed gudbinta iftiinka buluuga ah iyo iftiinka cas ayaa saameyn yar ku leh gudbinta iftiinka muraayadda, taas oo ah, miisaanka iftiinka buluugga ah iyo band iftiinka cas sidoo kale waa mid yar.Hab wax ku ool ah oo lagu ogaan karo waxqabadka ka-hortagga ultraviolet ee muraayadaha indhaha waa in tiro ahaan la go'aamiyo lana falanqeeyo gudbinta UVA iyo UVB spectra.
2. Qalabka tijaabada iyo hababka
Tijaabada gudbinta spectral waxaa loo isticmaali karaa in lagu cabbiro gudbinta spectral ee muraayadaha qorraxda ee gobolka ultraviolet si loo go'aamiyo tayada gudbinta ultraviolet ee muunada.Ku xidh mitirka gudbinta spectral-ka ee dekedda taxanaha ah ee kombiyuutarka, billow barnaamijka hawlgalka, samee cabbirida deegaanka 23°C±5°C (kahortaynta, waa in la xaqiijiyo in qaybta cabbiradu aanay lahayn lens ama filter), oo deji tijaabada dhererka hirarka ilaa 280 ~ 480 nm, u fiirso fallaadhaha ultraviolet ee lenska hoos yimaada xaaladda weynaynta qalooca gudbinta.Ugu dambayntii, dhig muraayadaha la tijaabiyey dushooda caagagga tijaabada si aad u tijaabiso gudbinta iftiinka (xusuusnow: masax muraayadaha iyo furayaasha caagga tijaabada ah nadiif ka hor inta aanad tijaabin).
3. Dhibaatooyinka cabbirka
Marka la ogaado muraayadaha muraayadaha, xisaabinta gudbinta ee band ultraviolet waxay qabataa hab fudud oo lagu qiyaaso gudbinta spectral, taas oo lagu qeexay sida celceliska gudbinta.Isla muunadda tijaabada ah, haddii labada qeexitaan ee QB2457 iyo ISO8980-3 loo isticmaalo cabbirka, natiijooyinka gudbinta mawjadaha ultraviolet ee la helay gabi ahaanba way kala duwan yihiin.Marka la cabbiro iyadoo loo eegayo qeexida ISO8980-3, natiijada la xisaabiyay ee gudbinta UV-B waa 60.7%;iyo haddii loo cabbiro si waafaqsan qeexida QB2457, natiijada la xisaabiyay ee gudbinta UV-B band waa 47.1%.Natiijooyinka waxay ku kala duwan yihiin 13.6%.Waxaa la arki karaa in farqiga u dhexeeya heerka tixraaca uu si toos ah u horseedi doono farqiga u dhexeeya shuruudaha farsamada, iyo ugu dambeyntii saameyn ku yeelanayso saxnaanta iyo ujeeddooyinka natiijooyinka cabbirka.Marka la cabbirayo gudbinta alaabada muraayadaha indhaha, dhibaatadan lama iska indho tiri karo.
Gudbinta alaabta muraayadaha iyo qalabka muraayadaha waa la tijaabiyaa oo la falanqeeyaa, qiimaha saxda ah waxaa lagu helaa isdhexgalka miisaanka ee gudbinta muraayadda, iyo natiijooyinka faa'iidooyinka iyo khasaarooyinka alaabta muraayadaha ayaa la helaa.Ugu horreyntii, waxay kuxirantahay in walxaha muraayadda ay xannibi karaan fallaadhaha ultraviolet, UVA iyo UVB, waxayna gudbin karaan iftiin badan oo muuqda si loo gaaro shaqada ka hortagga.Tijaabooyinku waxay muujiyeen in waxqabadka gudbinta ee lenses resin uu yahay kan ugu fiican, oo ay ku xigto muraayadaha muraayadaha, iyo muraayadaha muraayadaha ayaa ah kuwa ugu xun.Waxqabadka gudbinta ee lenses CR-39 ee lenses resin ayaa aad uga fiican PMMA.
