Metsoalle e ratehang, ha u khetha likhalase, na u atisa ho ipotsa hore na u ka khetha thepa ea lense joang?
Kajeno ke u arolelana tsebo e ncha
Ha e le hantle, ha ho thata ho khetha likhalase tse ntle.Pele ho tsohle, re lokela ho nahana ka thepa ea likhalase.Lisebelisoa tse fapaneng li na le litlamorao tse fapaneng.
Mona ke tse ling tsa lisebelisoa tse atileng haholo tsa liaparo tsa mahlo:
①Khalase (e boima/e robeha/e hana ho apara)
Lilense tsa khalase li khetholloa ka ho hlaka ho holimo le boima bo phahameng.Bothata ke hore li robeha habonolo 'me li batla li le boima.Hona joale ka kakaretso ha re khothaletse ho reka mofuta ona oa lense.
②CR39 lense (e bobebe / e nyane e brittle / e sa sebetseng ho feta)
Lilense tsa resin hajoale li sebelisoa haholo ebile ke lisebelisoa tsa boleng bo holimo.Molemo ke hore e batla e le bobebe, ha e na tšusumetso, 'me ha ho bonolo ho e senya.Ka nako e ts'oanang, e monya mahlaseli a ultraviolet ho feta lilense tsa khalase, hape e ka eketsa lisebelisoa tse khahlanong le mahlaseli a kotsi.
③PC (e bobebe haholo / ha e brittle / e sa senyeheng)
Lilense tsa PC ke polycarbonate, e leng thepa ea thermoplastic.Molemo ke hore e bobebe ebile e bolokehile.E loketse likhalase tse se nang rimless.Ka kakaretso e loketse tlhahiso ea likhalase tsa letsatsi, ke hore, likhalase tsa liipone tse bataletseng.
④Lilense tsa tlhaho (tse thata ebile ha li aparoe)
Lilense tsa tlhaho ha li sebelisoe hangata hona joale.Ka mohlala, quartz e na le melemo ea boima bo phahameng le ho hanyetsa ho apara, empa bobe ke hore ha e khone ho monya ka ho feletseng mahlaseli a ultraviolet le a infrared.
Kahoo metsoalle, haeba u roala likhalase, ho kgothaletswa ho sebelisa lilense tsa resin.Boitsebiso bona bo sebelisoa haholo hona joale ~ ~
