Ndeipi lens yezvinhu iri nani?

1.67 HMC
Magirazi zvishoma nezvishoma ave chinhu chinofanira-kuva nevanhu vazhinji, asi vanhu vazhinji vanovhiringidzika chaizvo pamusoro pekusarudza lenses.Kana kuenzanisa kusina kunaka, hazvizongokundikani kugadzirisa maonero, asiwo zvinokuvadza hutano hwedu hwemaziso, saka tingasarudza sei. lenzi chaiyo kana uchiwana magirazi?

 

(1) dzakaonda uye dzakareruka

Iwo akajairika refractive indices eCONVOX lenzi ndeaya: 1.56, 1.59, 1.61, 1.67, 1.71, 1.74.Pasi pedhigirii rimwe chetero, iyo yakakwira iyo refractive index yelens, iyo inosimba kugona kudzoreredza chiitiko chiedza, iyo lenzi yakatetepa uye inorema huremu.Yakareruka uye yakasununguka kupfeka.

(2) Kujeka

Iyo refractive index haingotaridzi ukobvu hwelens, asiwo inobata nhamba yeAbbe.Iyo yakakura nhamba yeAbbe, idiki yekuparadzira.Sezvineiwo, iyo idiki nhamba yeAbbe, yakakura kupararira, uye zvakanyanya kujeka kwekufungidzira.Asi kazhinji kutaura, iyo yakakwirira iyo refractive index, iyo yakakura kupararira, saka hutete uye kujeka kwe lens kazhinji hazvigone kuverengerwa.

(3) Chiedza chekufambisa

Chiedza chekufambisa zvakare chimwe chezvinhu zvinokanganisa kunaka kwelens.Kana chiedza chakanyanya kusviba, kutarisa zvinhu kwenguva yakareba kunokonzera kuneta kwekuona, izvo zvisingabatsiri kuhutano hwemaziso.Zvishandiso zvakanaka zvinogona kuderedza kurasikirwa kwechiedza, uye mwenje wekufambisa mhedzisiro yakanaka, yakajeka uye yakajeka.Ipa iwe kuona kwakajeka.

 (4) UV kudzivirira

Chiedza cheUltraviolet chiedza chine wavelength ye10nm-380nm.Yakawandisa ultraviolet mwaranzi inokonzeresa kukuvadza kumuviri wemunhu, kunyanya maziso, uye kunyange kukonzera upofu mumatambudziko akaomarara.Panguva ino, iyo anti-ultraviolet basa re lens inonyanya kukosha.Inogona kunyatso kuvharira ultraviolet rays pasina kukanganisa mafambiro echiedza chinooneka, uye kudzivirira maziso pasina kukanganisa maitiro ekuona.
