1. Molao-motheo oa ho lemoha phetiso ea lense ea UV
Tekanyo ea phetisetso ea lilense tsa likhalase tsa letsatsi e ke ke ea sebetsoa e le karolelano e bonolo ea phetisetso ea spectral ho bolelele bo bong le bo bong, empa e lokela ho fumanoa ka ho kopanya boima ba phetisetso ea spectral ho latela boima ba maqhubu a fapaneng a maqhubu.Leihlo la motho ke mokhoa o bonolo oa optical.Ha ho hlahlojoa boleng ba likhalase, kutloisiso ea leihlo la motho ho mahlaseli a khanyang a li-wavelengths tse fapaneng e tlameha ho qala ho nahanoa.Ka bokhutšoanyane, leihlo la motho le ela hloko leseli le letala, kahoo ho fetisoa ha sehlopha sa leseli le letala ho na le tšusumetso e kholo ho phetiso ea leseli la lense, ke hore, boima ba lebone le letala bo boholo;ho fapana le hoo, hobane leihlo la motho ha le amehe ka leseli le pherese le leseli le lefubelu, kahoo Phetiso ea leseli le pherese le leseli le lefubelu li na le phello e nyane ho phetiso ea leseli ea lense, ke hore, boima ba leseli le pherese. red light band e boetse e batla e le nyane.Mokhoa o atlehang oa ho lemoha tšebetso e khahlanong le ultraviolet ea lilense ke ho tseba ka bongata le ho sekaseka phetisetso ea likhahla tsa UVA le UVB.
2. Lisebelisoa tsa liteko le mekhoa
Teko ea spectral transmittance tester e ka sebelisoa ho lekanya phetiso ea spectral ea likhalase tsa letsatsi sebakeng sa ultraviolet ho fumana boleng ba phetisetso ea ultraviolet ea sampole.Hokela meter ea spectral transmittance koung ea serial ea komporo, qala lenaneo la ts'ebetso, etsa tlhahlobo ea tikoloho ho 23 ° C ± 5 ° C (pele ho tekanyetso, e tlameha ho netefatsoa hore karolo ea ho lekanya ha e na lense kapa filthara), 'me u behe tlhahlobo. bolelele ba maqhubu ho fihla ho 280 ~ 480 nm, hlokomela mahlaseli a ultraviolet a lense tlas'a boemo ba ho holisa lekhalo la phetisetso.Qetellong, beha lilense tse lekiloeng holim'a li-plug tsa rabara tsa teko ho hlahloba phetisetso ea leseli (hlokomela: hlakola lilense le li-plug tsa rabara tsa teko pele ho tlhahlobo).
3. Mathata tekanyong
Ha ho fumanoa likhalase tsa letsatsi, palo ea phetisetso ea sehlopha sa ultraviolet e nka mokhoa o bonolo oa ho lekanya phetisetso ea spectral, e hlalosoang e le karolelano ea phetisetso.Bakeng sa sampole e tšoanang tlas'a teko, haeba litlhaloso tse peli tsa QB2457 le ISO8980-3 li sebelisetsoa ho lekanya, liphetho tsa phetisetso ea waveband ea ultraviolet e fumanoeng li fapane ka ho felletseng.Ha e lekantsoe ho ea ka tlhaloso ea ISO8980-3, sephetho se baloang sa phetiso ho sehlopha sa UV-B ke 60.7%;'me haeba e lekantsoe ho ea ka tlhaloso ea QB2457, sephetho se baliloeng sa phetisetso ho sehlopha sa UV-B ke 47.1%.Liphetho li fapane ka 13.6%.Ho ka bonoa hore phapang ea litekanyetso tsa litšupiso e tla lebisa ka ho toba phapanong ea litlhoko tsa tekheniki, 'me qetellong e ama ho nepahala le sepheo sa liphetho tsa tekanyo.Ha u lekanya phetisetso ea lihlahisoa tsa mahlo, bothata bona bo ke ke ba hlokomolohuoa.
Ho fetisoa ha lihlahisoa tsa likhalase tsa mahlaseli le lisebelisoa tsa lense ho lekoa le ho hlahlojoa, 'me boleng bo nepahetseng bo fumanoa ka ho kopanya boima ba phetisetso ea spectral,' me liphello tsa melemo le boiketlo ba lihlahisoa tsa likhalase li fumanoa.Ntlha ea pele, ho itšetlehile ka hore na thepa ea lense e ka thibela mahlaseli a ultraviolet, UVA le UVB, 'me e ka fetisa leseli le bonahalang haholoanyane ho finyella ts'ebetso ea anti-glare.Liteko li bontšitse hore ts'ebetso ea phetisetso ea lilense tsa resin ke eona e ntle ka ho fetisisa, e lateloa ke lilense tsa khalase, 'me lilense tsa kristale ke tsona tse mpe ka ho fetisisa.Ts'ebetso ea phetisetso ea lilense tsa CR-39 har'a lilense tsa resin e ntle haholo ho feta PMMA.
