M'nkhaniyi, ife makamaka kulankhula za mmene ife kuyesa khalidwe lamagalasi magalasi.Kwa ife, ubwino wa lens umadalira maonekedwe ndi ntchito.
Tonse tikudziwa kuti mandala ndi amodzi mwamagawo ofunikira kwambiri pawirimagalasi, khalidwe la lens limagwirizana mwachindunji ndi khalidwe la magalasi.Timawononga ndalama zambiri, ndipo tikuyembekeza kugula peyalamagalasi abwino.Ndikosavuta kusankha awirimagalasizomwe mumakonda potengera maonekedwe, koma ntchito ya magalasi ndi yofunika kwambiri.Tiyeni tiwone momwe fakitale imayenderakhalidwewa ma lens.Zachidziwikire, ngati ndinu ogula wamba, ndikhulupilira kuti zikuthandizani.
1. Kuyang'anira maonekedwe.Kwa mtundu, mtundu wa variegated, pitting, scratches ndi mavuto ena pamwamba.Ikani chidutswa cha pepala loyera losaipitsa pansi pake, ndipo fufuzani mosamala ngati pali mavuto omwe ali pamwambawa pansi pa kuwala kwa QC (kuwala kolimba komanso kofananako kuposa kuwala kwa masana wamba).
2. cheke tsatanetsatane.Chifukwa mandala nthawi zambiri amakhala ozungulira, tifunika kugwiritsa ntchito dipstick caliper kuti tiyeze kukula kwake ndi makulidwe ake.
3. Kuyesa kwa Anti-friction.Gwiritsani ntchito pepala linalake laukali kapena nsalu kapena zipangizo zina kuti muzipaka pamwamba pa mandalawo mmbuyo ndi mtsogolo kwa nthawi zingapo ndi mphamvu inayake, ndiyeno muwone zotsatira zake.Mapangidwe apamwambamagalasi ali ndi anti-friction effect.
4. Camber kuyendera: Yang'anani camber ya mandala ndi mita ya camber.Malo oyendera ndi mtengo wopindika wapakati pa mandala komanso osachepera 4 mfundo zozungulira.Mukuwunika kotsatira kwa batch, ikani pansi pa mbale yagalasi kuti muwone ngati ikukhudzana ndi mbale yagalasi.
5.Impact resistance test.Zomwe zimatchedwanso kuyesa kwa mpira, gwiritsani ntchito choyezera mpira kuti muyese kukana kwa lens.
6. Mayeso a ntchito ya lens.Choyamba, zimatengera ntchito yeniyeni ya mandala, ndiyeno amayesa mayeso ofanana.Zodziwika bwino ndizosavomerezeka ndi mafuta, osalowa madzi, olimbikitsidwa, etc., UV400, polarized, etc.
• A. Mayeso osagwira ntchito ngati mafuta: Gwiritsani ntchito cholembera chopangidwa ndi mafuta kuti mujambule pamwamba pa mandala.Ngati imatha kusonkhana mwachangu, ipukuteni ndi mandala mopepuka, kusonyeza kuti ili ndi ntchito yoteteza mafuta.Yang'anani kuchuluka kwa madzi amafuta akusonkhanitsidwa pamodzi, ndikupukuta.Digiri yoyera, yang'anani zotsatira zake zotsutsana ndi mafuta.
• B. Kuyesa ntchito yoletsa madzi: ikani mandala m'madzi oyera ndikuitulutsa, igwedezeni pang'ono, madzi pamtunda adzagwa, kusonyeza kuti lens ili ndi ntchito yopanda madzi.Yang'anani momwe madzi amachitira molingana ndi mlingo wa dontho.
• C. Kulimbitsa ntchito kuyesa: Pansi pa kuwala kwa QC, onani ngati pali guluu woonekera pamwamba ndi periphery ya mandala, ndi kufinya pang'onopang'ono ndi tsamba.Ili ndi mphamvu yabwino komanso yolimba.
• D. Polarization ntchito kuyesa: yesani ndi polarizer.Kapena tsegulani fayilo ya WORD ya pakompyuta, ndiyeno gwirani disolo yoyang'anizana nayo ndikuizungulira mozungulira, mtundu wa lens udzasintha kuchokera ku kuwala kupita kumdima kenako wakuda kwathunthu, ndikupitirizabe kuzungulira kuchokera kukuda mpaka kuwala pang'onopang'ono.Ndi polarizer.Samalani kuti muwone kufanana kwa mtunduwo, ndi zina zotero, komanso ngati kuli mdima wokwanira kuti muweruze ubwino wa polarizing ntchito pamene ili opaque.
• E. UV400 amatanthauza 100% chitetezo cha UV.Magalasi adzuwapamsika mwina si onse ali ndi zotsatira za kudzipatula cheza ultraviolet.Ngati mukufuna kudziwa ngati magalasi amatha kupatula kuwala kwa ultraviolet: pezani nyali yowunikira ndalama ya ultraviolet.ndi banki.Ngati inu mwachindunji kuunikirait, mutha kuwona ultraviolet anti-counterfeiting yandalama.Ngati kudzera mu mandala omwe ali ndi UV400 ntchito, zotsutsana ndi zabodza sizingawoneke.
Zomwe zili pamwambazi ndi njira zowunika ndi kuyesa ma lens.Inde, palibe muyezo wathunthu wa izo.Makasitomala aliyense ndi mtundu uliwonse ali ndi zofunikira zosiyanasiyana zamagalasi.Ena amasamalira kwambiri mawonekedwe ndipo ena amalabadira kwambiri ntchito, kotero kuyang'ana koyang'anira kudzakhalanso kosiyana.
