1.59 PC Blue Hlais HMC Optical lo ntsiab muag
PC lo ntsiab muag, cov lo ntsiab muag dav dav yog cov khoom siv thermosetting, uas yog, cov khoom siv raw yog kua, rhuab los ua cov khoom lo ntsiab muag. PC daim tseem hu ua "qhov chaw", "qhov chaw", lub npe tshuaj yog polycarbonate rog, yog cov khoom siv thermoplastic. Ntawd yog, cov khoom siv raw yog cov khoom, rhuab tom qab shaping rau hauv lo ntsiab muag, yog li no lo ntsiab muag yuav overheated tom qab cov khoom tiav lawm yuav deformed, tsis haum rau high humidity thiab tshav kub zaus.
PC lo ntsiab muag muaj ib tug muaj zog toughness, tsis tawg (2cm yuav siv tau rau mos mos iav), yog li nws tseem hu ua kev ruaj ntseg lens. Qhov tshwj xeeb lub ntiajteb txawj nqus tsuas yog 2 grams ib cubic centimeter, ua rau nws cov khoom siv lightest tam sim no siv rau lo ntsiab muag.

1.74 Blue Coat HMC Optical lo ntsiab muag
Qhov tsom iav 1.74 txhais tau hais tias lub lens nrog qhov ntsuas pom ntawm 1.74, uas yog ib qho uas muaj qhov ntsuas siab tshaj plaws ntawm lub khw, thiab ib qho nrog lub lens tuab tshaj plaws. Lwm qhov tsis sib npaug, qhov siab dua qhov ntsuas qhov ntsuas pom, lub lens thinner, thiab nws yuav kim dua. Yog hais tias qhov degree ntawm myopia yog ntau tshaj 800 degrees, nws yog suav hais tias yog ultra-siab myopia, thiab ib tug refractive index ntawm 1.74 yog haum.

1.61 MR-8 Xiav Hlais Ib Lub Zeem Muag HMC Optical lo ntsiab muag
1.60 txhais tau hais tias lub lens refractive index yog 1.60, qhov siab dua qhov refractive index, lub thinner lub lens ntawm tib degree.
MR-8 yog polyurethane resin lens.
1. Ntawm tag nrho 1.60 lo ntsiab muag, nws qhov kev ua haujlwm kho qhov muag kuj zoo heev, thiab tus lej Abbe tuaj yeem ncav cuag 42, uas txhais tau hais tias qhov pom tseeb thiab kev ncaj ncees ntawm kev pom yuav siab dua;
2. Nws lub zog tensile tuaj yeem ncav cuag 80.5, uas zoo dua li cov ntaub ntawv lo ntsiab muag;
3. Nws qhov kub tsis kam tuaj yeem ncav cuag 100 ℃, qhov kev ua tau zoo yog qhov ruaj khov, qhov kev faib ua feem kuj tseem qis.

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.
