1.71 Magalasi a Single Vision HMC Optical

Kufotokozera Kwachidule:

Lenzi ya 1.71 Dzina lonse la lenzi ya 1.71 refractive index, yokhala ndi refractive index yapamwamba, transmittance yayikulu, makhalidwe apamwamba a Abbe number, ngati ili ndi digiri yomweyo ya myopia, ingachepetse kwambiri makulidwe a lenzi, kuchepetsa ubwino wa lenzi, nthawi yomweyo, kupangitsa lenzi kukhala yoyera komanso yowala, yosasavuta kufalitsa tinthu ta utawaleza. Zapezeka kuti kuwonjezera cyclic sulfide resin mu zinthu za lenzi kungathandize kuti refractive index ya lenzi ikwere, koma cyclic sulfide resin yambiri ingayambitse kuchepa kwa transmittance ya kuwala ndi kusweka kwa zinthu. Mwa kuwongolera bwino kuchuluka kwa ring sulfure resin mu 1.71KR resin, lenzi ya 1.71 imapeza refractive index yayikulu ndi abbe number pamene ikutsimikizira kuti kuwala kumayenda bwino, kufalikira kochepa komanso kuwona bwino.

Chizindikiro cha lenzi chimatanthauza chizindikiro cha refraction (chomwe chimadziwikanso kuti refractive index) cha zinthu za lenzi za maso. Ndi nambala yoyezera yomwe imafotokoza momwe zinthuzo zimapindirira kuwala bwino. Kupendekera kwa kuwala kudzadalira momwe kuwalako kumadutsa mwachangu kudzera mu lenzi.

Zipangizo za lenzi zimagawidwa pa refractive index yawo. Refractive index iyi ndi chiŵerengero cha liwiro la kuwala pamene likuyenda mumlengalenga ndi liwiro la kuwala pamene likudutsa mu lenzi. Ndi chizindikiro cha kuchuluka kwa kuwala komwe kumapindika pamene likuyenda mu lenzi. Kuwala kumapindika, kapena kupindika, pamwamba pa lenzi, kenako pamene likutuluka mu lenzi. Zipangizo zokhuthala zimapindika kuwala kwambiri, kotero sipakufunika zinthu zambiri kuti zikwaniritse zotsatira zofanana za refractive monga zinthu zochepa. Chifukwa chake lenzi ikhoza kupangidwa kukhala yopyapyala, komanso yopepuka.

Chiyambi cha Kupanga

Ndi magalasi a magalasi anthawi zonse, pakati pa magalasiwo pamakhala poonda ndipo m'mbali mwa magalasiwo ndi zokhuthala kuti zithandize kupendekera kwa kuwala komwe kumachititsa kuti magalasi olembedwa ndi dokotala agwire ntchito! Magalasi okhala ndi ma index apamwamba amakhala ndi index yayikulu ya kupendekera kwa kuwala kuposa magalasi anthawi zonse, zomwe zikutanthauza kuti safunika kukhala okhuthala kwambiri m'mbali kuti agwire ntchito.

Magalasi okhala ndi ma index apamwamba amatanthauza kuti lenzi yokhayo ikhoza kukhala yopyapyala komanso yopepuka. Izi zimathandiza kuti magalasi anu akhale okongola komanso omasuka momwe mungathere. Magalasi okhala ndi ma index apamwamba ndi othandiza kwambiri ngati muli ndi mankhwala amphamvu a magalasi a maso kwa odwala omwe ali ndi vuto la kuwona pafupi, kuwona patali, kapena astigmatism. Komabe, ngakhale omwe ali ndi mankhwala ochepa a magalasi a maso angapindule ndi magalasi okhala ndi ma index apamwamba.

1.71 ndi chinthu chothandizira kuukira. Kawirikawiri, chizindikiro cha refractive chikakhala chachikulu, nambala ya Abbe imakhala yotsika. Nambala ya Abbe ya 1.67 ndi 32, 1.74 ndi 33, ndipo 1.71 imatha kuchita 37. Kuukira kumeneku kumapambana. Nambala ya Abbe ndi yayikulu, kufalikira kwake ndi kochepa, zomwe zimveka bwino. 1.67 ndi yotsika mtengo kwambiri kuposa 1.74, koma ndi yokhuthala kwambiri pankhani ya kutalika. 1.74 ndi yopyapyala, koma mtengo wake ndi wokwera, kutalika kwapakati ndi kwakukulu. Anzanu ambiri amatha kusankha 1.67 yokha pa chikwama chawo. Ndipo 1.71 imadzaza kusiyana kumeneko.
