Okondedwa, posankha magalasi, kodi nthawi zambiri mumadabwa momwe mungasankhire zinthu za lens?
Lero ndikugawana nanu chidziwitso chatsopano
Kwenikweni, sizovuta kusankha magalasi abwino.Choyamba, tiyenera kuganizira zinthu za magalasi.Zida zosiyanasiyana zimakhala ndi zotsatira zosiyana.
Nazi zina mwazovala zamaso zomwe zimapezeka kwambiri:
①Magalasi (olemera/osalimba/osavala)
Magalasi agalasi amadziwika ndi kumveka bwino komanso kuuma kwakukulu.Choyipa chake ndi chakuti nzosavuta kuthyoka komanso ndi olemera.Tsopano ife si amalangiza kugula mtundu wa mandala.
②CR39 lens (yopepuka / yocheperako / yosamva kuvala)
Ma lens a resin amagwiritsidwa ntchito kwambiri pakadali pano ndipo ndi zida zapamwamba kwambiri.Ubwino wake ndikuti ndi wopepuka, wosakhudzidwa, komanso wosavuta kuswa.Panthawi imodzimodziyo, imatenga kuwala kwa ultraviolet bwino kuposa magalasi agalasi, ndipo imatha kuwonjezera zinthu zotsutsana ndi ultraviolet.
③PC (yopepuka kwambiri / yopanda brittle / yosavala)
Ma lens a PC ndi polycarbonate, yomwe ndi zinthu za thermoplastic.Ubwino wake ndikuti ndi wopepuka komanso wotetezeka.Ndizoyenera magalasi opanda malire.Nthawi zambiri ndi yoyenera kupanga magalasi adzuwa, ndiko kuti, magalasi a magalasi athyathyathya.
④Magalasi achilengedwe (olimba komanso osavala)
Magalasi achilengedwe sagwiritsidwa ntchito kawirikawiri.Mwachitsanzo, quartz ili ndi ubwino wa kuuma kwakukulu ndi kukana kuvala, koma kuipa kwake ndikuti sikungathe kuyamwa bwino cheza cha ultraviolet ndi infrared.
Kotero abwenzi, ngati mumavala magalasi, ndi bwino kugwiritsa ntchito magalasi a resin.Izi zimagwiritsidwanso ntchito kwambiri masiku ano ~~
