Bahlobo abathandekayo, xa ukhetha iiglasi, ngaba uhlala uzibuza indlela yokukhetha izinto eziphathekayo zelensi?
Namhlanje ndikwabelana nawe ngolwazi olutsha
Enyanisweni, akunzima ukukhetha iiglasi ezilungileyo.Okokuqala, kufuneka siqwalasele izinto zeeglasi.Izinto ezahlukeneyo zineempembelelo ezahlukeneyo.
Nazi ezinye zezona zinto zixhaphakileyo zempahla yamehlo:
①Iglasi (inzima/eethe-ethe/inganxibi)
Iilensi zeglasi zibonakaliswa ngokucaca okuphezulu kunye nobunzima obuphezulu.Ingxaki kukuba kulula ukuziqhawula kwaye zinzima kakhulu.Ngoku ngokuqhelekileyo asicebisi ukuthenga olu hlobo lwelensi.
②CR39 ilens (ikhaphukhaphu / incinci ibrittle / iyakwazi ukunxiba)
Iilensi zeresin ngoku zisetyenziswa kakhulu kwaye zizixhobo ezikumgangatho ophezulu.Inzuzo kukuba ilula, ayinyangeki, kwaye akukho lula ukuyiqhawula.Kwangaxeshanye, ifunxa imitha ye-ultraviolet engcono kuneeglasi zeglasi, kwaye inokongeza izinto ezichasene ne-ultraviolet.
③PC (ikhaphukhaphu kakhulu / ayinankumnkum / ayinxibi)
Iilensi zePC ziyi-polycarbonate, eyona nto i-thermoplastic.Inzuzo kukuba ilula kwaye ikhuselekile.Ifanelekile kwiiglasi ezingenamsinga.Ngokuqhelekileyo ifanelekile ukuveliswa kwezibuko zelanga, oko kukuthi, izibuko zezibuko zeglasi.
④Ielensi zendalo (zinzima kwaye azigugi)
Iilensi zendalo azifane zisetyenziswe ngoku.Ngokomzekelo, i-quartz ineenzuzo zobunzima obuphezulu kunye nokuxhatshazwa kokugqoka, kodwa i-disadvantage kukuba ayikwazi ukufunxa ngokupheleleyo i-ultraviolet kunye nemitha ye-infrared.
Ngoko bahlobo, ukuba unxibe iiglasi, kuyacetyiswa ukuba usebenzise iilensi ze-resin.Le mathiriyeli ikwasetyenziswa ngokubanzi ngoku ~~
