Lenzi yepurasitiki inogadzirwa nejekiseni
Ruzivo rwechigadzirwa:
Matekiniki ekugadzira majekiseni e optical inzira inodhura zvishoma yekugadzira malenzi epurasitiki nemazvo. Yakakodzera kugadzira malenzi epurasitiki akawanda ane nzvimbo dzakatenderera, dzakaita sedenderedzwa uye dzakareruka. Kugadzira majekiseni e optics kunogona kudzokororwa zvakanyanya uye kwakarurama. Zvikuru nekuda kwekunyatsogadzirwa kwema molds uye kunyatsogadzirwa kwawo.
Pane zvinhu zvitatu zvikuru zvinokonzerwa nekupinza majekiseni nemazvo: muchina wekugadzira majekiseni, maforoma uye nzira yekudzvanya. Hunhu hwemaforoma ndihwo hunosarudza hunhu hwechikamu chekupedzisira zvakananga. Maforoma akavakwa nechikamu chakakombama. Kureva kuti, kana uchida nzvimbo yakakombama, foroma inenge yakakombama. Maforoma akagadzirwa ne alloy, uye akagadzirwa ne lathe yakanyatsonaka. Zvikamu zvakawanda zvinogona kudzvanywa panguva imwe chete nemaburi akawanda paforoma. Hazvirevi kuti zvinofanira kunge zvakafanana; modhi yakasiyana ye lens inogona kuvakwa mumaburi akasiyana paforoma imwe chete uye kugadzirwa panguva imwe chete kuchengetedza mari yeforoma, ukuwo ichideredza kumhanya kwekugadzirwa kwemodhi yega yega yezvikamu.
Kugadzira ma prototype kunodiwa usati wagadzira batch. Ma mold acho achagadzirwa uye kugadzirwa zvichienderana nezvinodiwa ne optical. Anogona kuchinjwa kuti ave nechokwadi chekuti zvikamu zvekupedzisira zvinokwanisa kusangana nezvinodiwa nevatengi. Mukugadzira batch, pachava nekutarisa kwekutanga kwechinhu pamwe nekutarisa mukati mekugadzira panguva yekugadzira. Uye chikamu chekupedzisira chakagadzirwa chichachengetwa kuti chiongororwe mune ramangwana.
Zvinhu zvepurasitiki hazvigoni kumira tembiricha yakanyanya kupfuura iyo machira akaiswa pairi

Mashoko:
Kugadziriswa kwechigadzirwa ichi kunowanikwa kuti chienderane nezvinodiwa nehunyanzvi hwako. Tizivise zvaunoda.
