Isici esisodwa esibalulekile okufanele sicatshangelwe lapho ukhetha amalensi impahla yelensi.
Ipulasitiki ne-polycarbonate yizinto ezijwayelekile zamalensi ezisetshenziswa emigqonyeni yamehlo.
Ipulasitiki ilula futhi ihlala isikhathi eside kodwa ishubile.
I-Polycarbonate izacile futhi inikeza isivikelo se-UV kodwa iklwebheka kalula futhi ibiza kakhulu kunepulasitiki.
Into ngayinye yelensi inezimfanelo ezihlukile ezenza ifaneleke kakhulu amaqembu athile eminyaka yobudala, izidingo nezindlela zokuphila. Lapho ukhetha impahla ye-lens, kubalulekile ukucabangela:
●Isisindo
●Ukumelana nomthelela
●Ukumelana nokunwaya
●Ubukhulu
● Ukuvikelwa kwe-Ultraviolet (UV).
●Izindleko
Uhlolojikelele lwamalensi epulasitiki
Amalensi epulasitiki ayaziwa nangokuthi i-CR-39. Le nto isetshenziswe kabanzi kwezingubo zamehlo kusukela ngeminyaka yawo-1970s futhi iseyinketho ethandwayo kubantu abagqoka izibuko ezinikezwe udokotela ngenxayayoizindleko eziphansi nokuqina. I-coating engazweli, i-tint ne-ultraviolet (UV) evikelayo ingafakwa kalula kulawa ma-lens.
●Isindo esingasindi -Uma kuqhathaniswa nengilazi yomqhele, ipulasitiki ilula. Izibuko ezinamalensi epulasitiki zikhululekile ukuzigqoka isikhathi eside.
●Ukucaca okuhle kokubona -Amalensi epulasitiki anikeza ukucaca okuhle kokubona. Ababangeli ukuhlanekezelwa okuningi kokubona.
●Ihlala isikhathi eside -Amalensi epulasitiki mancane amathuba okuthi aphuke noma aphihlike kunengilazi. Lokhu kubenza babe ukukhetha okuhle kubantu abakhuthele, nakuba bengenabo ubufakazi bokuphahlazeka njenge-polycarbonate.
●Kubiza kancane –Amalensi epulasitiki ngokuvamile abiza kancane kune-polycarbonate.
● Ukuvikelwa kwe-UV okuncane –Ipulasitiki inikeza ukuvikeleka okuncane kuphela emisebeni ye-UV eyingozi. I-UV kufanele ifakwe ukuze ivikeleke ngo-100% uma uhlela ukugqoka izibuko ngaphandle.
Ukubuka konke kwamalensi e-polycarbonate
I-Polycarbonate iwuhlobo lwepulasitiki olungazweli kakhulu oluvame ukusetshenziswa ezimpahleni zamehlo. Amalensi okuqala e-polycarbonate ezohwebo aqalwa ngawo-1980, futhi akhula ngokushesha ekudumeni.
Le nto yelensi imelana ngokuphindwe kashumi kunepulasitiki. Ngenxa yalesi sizathu, ngokuvamile kunconywa izingane kanye nabantu abadala abakhuthele.
●Okuqinile -I-Polycarbonate ingenye yezinto eziqine futhi eziphephile ezisetshenziswa namuhla ezingilazini. Ngokuvamile kunconywa izingane ezincane, abantu abadala abakhuthele, kanye nabantu abadinga izingubo zamehlo zokuphepha.
●Izacile futhi ingasindi -Amalensi e-Polycarbonate azacile ngamaphesenti angama-25 kunepulasitiki yendabuko.
●Ukuvikelwa okuphelele kwe-UV -I-Polycarbonate ivimba imisebe ye-UV, ngakho-ke asikho isidingo sokwengeza i-UV enamathela ezingilazini zakho. Lawa ma-lens ayisinqumo esihle kubantu abachitha isikhathi esiningi bengaphandle.
●Kunconywa ukunamathela okumelana nokuklwebheka -Nakuba i-polycarbonate ihlala isikhathi eside, impahla isajwayele ukuklwebheka. Kunconywa ukunamathela okumelana nokuklwebheka ukusiza lawa ma lens ahlale isikhathi eside.
●Kunconywa ukumboza i-anti-reflective -Abanye abantu abanemiyalelo ephezulu babona ukubukeka kwendawo kanye nokufaka umbala uma begqoke amalensi e-polycarbonate. I-anti-reflective coating inconywa ukunciphisa lo mphumela.
●Umbono osontekile -I-Polycarbonate ingabangela ukubona okuzungezile okusontekile kulawo anemiyalelo eqinile.
●Ibiza kakhulu -Amalensi e-polycarbonate ngokuvamile abiza ngaphezu kwamalensi epulasitiki.
Ungathola ezinye izinketho zezinto ezisetshenziswa ilensi kanye nemisebenzi ngokubheka iwebhusayithi yethuhttps://www.universeoptical.com/stock-lens/. Nganoma yimiphi imibuzo, wamukelekile ukusithinta ukuze uthole ulwazi olwengeziwe.
