1.71 Ib Lub Zeem Muag HMC Optical lo ntsiab muag
1.71 lens Lub npe Tag Nrho 1.71 refractive index lens, nrog siab refractive index, siab transmittance, siab Abbe tus yam ntxwv, nyob rau hauv cov ntaub ntawv ntawm tib myopia degree, yuav txo tau lub thickness ntawm lub lens, txo qhov zoo ntawm lub lens, tib yam. lub sij hawm, ua rau lub lens ntau ntshiab thiab ci, tsis yooj yim rau disperse zaj sawv lis. Nws tau pom tias ntxiv cyclic sulfide resin rau hauv cov khoom siv lens tuaj yeem txhim kho qhov ntsuas qhov ntsuas ntawm lub lens, tab sis ntau dhau ntawm cyclic sulfide resin yuav ua rau txo qis ntawm lub teeb xa mus thiab cov khoom tawg. Los ntawm kev tswj xyuas cov ntsiab lus ntawm lub nplhaib sulfur resin hauv 1.71KR resin, 1.71 lub lens ua tiav qhov siab refractive index thiab abbe tooj thaum ua kom lub teeb pom kev zoo, tsis tshua muaj dispersion thiab pom tseeb dua.
