Muchikamu chino, tinonyanya kutaura nezvekuti tinoedza sei kunaka kwemagirazi lenzi.Kwatiri, kunaka kwe lens kunoenderana nechitarisiko uye basa.
Isu tese tinoziva kuti lens ndechimwe chezvakakosha zvikamu zvepairimagirazi, hutano hwe lens hunoenderana zvakananga nehutano hwemagirazi.Isu tinoshandisa mari yakawanda, uye isu tinotarisira kutenga peyamagirazi akanaka.Zviri nyore chaizvo kusarudza peyamagirazikuti unofarira maererano nechitarisiko, asi basa rema lenses rakakoshawo.Ngatitarisei kuti fekitori inoongorora seiqualityye lenzi.Ehe, kana uri mutengiwo zvake, ndinovimba zvichakubatsira.
1. Kuongororwa kwekuonekwa.Kune ruvara, variegated color, pitting, scratches uye mamwe matambudziko epamusoro.Isa chidimbu chemapepa machena asina kusvibisa pasi payo, uye nyatsotarisa kana pane chero matambudziko ari pamusoro apa pasi pechiedza cheQC (chakasimba uye chakafanana chiedza kupfuura chiedza chemasikati).
2. Specification cheki.Nekuda kwekuti lenzi inowanzotenderedzwa, tinoda kushandisa mafuta dipstick caliper kuyera dhayamita nekukora kwelenzi.
3. Anti-friction test.Shandisa rimwe bepa rakakasharara kana jira kana zvimwe zvinhu kukwiza pamusoro pe lens kumashure nekudzoka kwenhamba yakati yenguva neimwe simba, uye wozoona mhedzisiro.Yepamusoro-sorolenzi dzine zvirinani anti-friction effect.
4. Camber kuongorora: Tarisa camber yelens ine camber mita.Nzvimbo yekuongorora ndiyo curvature kukosha kwepakati pe lens uye inokwana 4 mapoinzi akaitenderedza.Muchikamu chinotevera chekuongorora, chiise chakatsetseka pandiro yegirazi kuti utarise kana yakaenzana yakabatana nendiro yegirazi.
5.Impact resistance test.Iyo inonziwo bvunzo yekudonha bhora, shandisa yekudonha bhora tester kuti uedze kupikisa kwelens.
6. Lens basa bvunzo.Chokutanga pane zvose, zvinoenderana nemabasa chaiwo e-lens, uye ozoita muedzo unoenderana.Iwo akajairika mafuta-chiratidzo, kusapinda mvura, kusimbiswa, nezvimwe, UV400, polarized, nezvimwe.
• A. Oil-proof function test: Shandisa peni yakagadzirwa nemafuta kudhirowa pamusoro pe lens.Kana ikakwanisa kuungana pamwe nekukasira, pukuta nelenzi zvishoma, zvichiratidza kuti ine basa rinodzivirira mafuta.Tarisa chiyero chemvura ine mafuta ichiungana pamwe chete, uye pukuta iyo.Yakachena dhigirii, ongorora ayo anti-oiri maitiro.
• B. Kuedza kwekushanda kwemvura: isa lens mumvura yakachena uye uibudise kunze, izunungusa zvishoma, mvura iri pamusoro ichadonha, zvichiratidza kuti lens ine basa rekudzivirira mvura.Tarisa maitiro ekudzivirira mvura zvichienderana nehuwandu hwekudonha.
• C. Kusimbisa basa rekuedza: Pasi pechiedza cheQC, cherechedza kana pane akajeka glue layer pamusoro pepamusoro uye periphery ye lens, uye zvinyoronyoro svina ne blade.Iine simba rakanaka uye kuoma.
• D. Polarization basa rekuedza: kuedza ne polarizer.Kana kuti vhura faira reWORD rekombuta, wobva wabata lenzi rakatarisa pariri woritenderedza newachi, ruvara rwelenzi rwunoshanduka kubva kuchiedza kuenda kurima uye robva rasviba zvachose, uye ramba uchitenderera kubva mutema uchienda kuchiedza zvishoma nezvishoma.Iyo inonzi polarizer.Chenjerera kuti utarise kufanana kweruvara, nezvimwewo, uye kana kwasviba zvakakwana kutonga kunaka kweiyo polarizing basa kana iri opaque.
• E. UV400 zvinoreva 100% UV kudzivirira.Magirazi ezuvapamusika vangasava vese vane mhedzisiro yekuparadzanisa ultraviolet mwaranzi.Kana iwe uchida kuziva kana lenzi inogona kuparadzanisa ultraviolet rays: tsvaga ultraviolet mari detector rambi.uye mari yebhengi.Kana iwe wakanyatsovhenekerait, iwe unogona kuona iyo ultraviolet inopesana nekunyepedzera yebanknote.Kana kuburikidza nelenzi ine UV400 basa, iyo anti-yekunyepedzera haigone kuonekwa.
Idzi dziri pamusoro ndedzimwe nzira dzekuongorora uye dzekuyedza lenzi.Chokwadi, hapana mwero wakakwana wazvo.Wese mutengi uye mhando yega yega ine zvakasiyana zvinodiwa lenzi.Vamwe vanonyanya kutarisisa kutaridzika uye vamwe vanobhadhara zvakanyanya kuita basa, saka iyo yekutarisisa yekutarisa ichave yakasiyana.
