Bangane abathandekayo, lapho ukhetha izibuko, ingabe uvame ukuzibuza ukuthi ungakhetha kanjani impahla ye-lens?
Namuhla ngikwabelana nawe ngolwazi olusha
Eqinisweni, akunzima ukukhetha izibuko ezinhle.Okokuqala, kufanele sicabangele impahla izibuko.Izinto ezihlukene zinemiphumela ehlukene.
Nazi ezinye zezinto ezivame kakhulu zezingubo zamehlo:
①Ingilazi (isinda/iphuka kalula/ingagugi)
Amalensi engilazi abonakala ngokucaca okuphezulu nobulukhuni obuphezulu.Ububi ukuthi kulula ukuphuka futhi asindayo uma kuqhathaniswa.Manje ngokuvamile asikhuthazi ukuthenga lolu hlobo lwamalensi.
②CR39 lens (ilula / i-brittle kancane / ukumelana okwengeziwe)
Njengamanje amalensi eresin asetshenziswa kakhulu futhi ayizinto ezisezingeni eliphezulu.Inzuzo ukuthi ilula uma iqhathaniswa, ayizweli, futhi akulula ukuyiphuka.Ngesikhathi esifanayo, ibamba imisebe ye-ultraviolet kangcono kunama-glass lens, futhi ingangeza izakhi ezilwa ne-ultraviolet.
③PC (ilula kakhulu / ayishwabanisi / ayizweli ukuguga)
Amalensi e-PC ayi-polycarbonate, okuyi-thermoplastic material.Inzuzo ukuthi ilula futhi iphephile.Ifanele izibuko ezingenarimless.Ngokuvamile kufanelekile ukukhiqizwa kwezibuko zelanga, okungukuthi, izibuko zezibuko eziyisicaba.
④Amalensi emvelo (aqinile futhi awagugi)
Amalensi emvelo awavamile ukusetshenziswa manje.Isibonelo, i-quartz inezinzuzo zokuqina okuphezulu nokumelana nokugqoka, kodwa okubi ukuthi ayikwazi ukumunca ngokugcwele imisebe ye-ultraviolet ne-infrared.
Ngakho-ke bangane, uma ugqoka izibuko, kunconywa ukusebenzisa ama-resin lens.Le nto isetshenziswa kabanzi njengamanje~~
