1.59 PC Xiav Txiav HMC Optical lenses
Cov iav PC, cov iav resin feem ntau yog cov khoom siv thermosetting, uas yog, cov khoom siv raw yog kua, cua sov kom ua cov iav khov. PC daim kuj tseem hu ua "space piece", "space piece", lub npe tshuaj yog polycarbonate rog, yog cov khoom siv thermoplastic. Uas yog, cov khoom siv raw yog khov, cua sov tom qab ua cov iav, yog li cov iav no yuav kub dhau tom qab cov khoom tiav lawm yuav raug deformed, tsis haum rau cov av noo siab thiab kub.
Lub lens PC muaj lub zog tawv, tsis tawg (2cm siv tau rau iav tiv thaiv mos txwv), yog li nws tseem hu ua lub lens kev nyab xeeb. Lub zog tshwj xeeb tsuas yog 2 grams ib cubic centimeter, ua rau nws yog cov khoom siv sib dua tshaj plaws tam sim no siv rau cov lens.

1.67 MR-7 Xiav Txiav HMC Optical lenses
Raws li tus qauv ISO, cov tsom iav tiv thaiv teeb xiav uas thaiv tau ntau tshaj 20% yog pom zoo rau kev siv txhua hnub ntawm cov khoom siv LED digital xws li TV, khoos phis tawj, pads thiab xov tooj ntawm tes. Cov tsom iav tiv thaiv teeb xiav uas thaiv tau ntau tshaj 40% raws li tus qauv ISO yog pom zoo rau cov neeg uas saib lub vijtsam ntau tshaj 8 teev hauv ib hnub. Vim tias cov tsom iav tiv thaiv teeb xiav lim tau ib feem ntawm lub teeb xiav, daim duab yuav daj thaum saib cov khoom, nws raug pom zoo kom hnav ob khub tsom iav, ib khub tsom iav ib txwm rau kev siv txhua hnub, thiab ib khub tsom iav tiv thaiv teeb xiav uas thaiv tau ntau tshaj 40% rau kev siv cov khoom siv LED digital xws li khoos phis tawj. Cov tsom iav tiv thaiv teeb xiav tiaj tiaj (tsis muaj degree) yog nrov heev ntawm cov neeg siv uas tsis muaj myopic, tshwj xeeb tshaj yog rau kev hnav khoos phis tawj hauv chaw ua haujlwm, thiab maj mam dhau los ua zam.

1.74 Xiav Coat HMC Optical lenses
Cov tsom iav 1.74 txhais tau tias lub lens nrog refractive index ntawm 1.74, uas yog qhov muaj refractive index siab tshaj plaws hauv kev ua lag luam, thiab qhov uas muaj lub lens tuab nyias tshaj plaws. Lwm cov kev ntsuas sib npaug, qhov refractive index siab dua, lub lens nyias dua, thiab nws yuav kim dua. Yog tias qib myopia ntau dua 800 degrees, nws suav tias yog ultra-high myopia, thiab refractive index ntawm 1.74 yog qhov tsim nyog.

1.61 MR-8 Xiav Txiav Ib Leeg Pom Kev HMC Optical lenses
1.60 txhais tau hais tias qhov refractive index ntawm lub lens yog 1.60, qhov siab dua qhov refractive index, qhov nyias dua lub lens ntawm tib qib.
MR-8 yog lub lens polyurethane resin.
1. Ntawm tag nrho cov iav 1.60, nws qhov kev ua tau zoo ntawm qhov muag pom tau zoo heev, thiab tus lej Abbe tuaj yeem ncav cuag 42, uas txhais tau tias qhov pom tseeb thiab qhov tseeb ntawm kev pom tej yam yuav siab dua;
2. Nws lub zog tensile tuaj yeem ncav cuag 80.5, uas zoo dua li cov ntaub ntawv lens ib txwm muaj;
3. Nws qhov kub tsis kam tuaj yeem ncav cuag 100 ℃, qhov kev ua tau zoo ruaj khov, qhov sib piv kuj tseem qis.

1.71 Ib Lub Zeem Muag HMC Optical lenses
1.71 lub lens Lub npe tag nrho 1.71 refractive index lens, nrog rau siab refractive index, siab transmittance, siab Abbe tus lej yam ntxwv, nyob rau hauv cov ntaub ntawv ntawm tib lub myopia degree, tuaj yeem txo qhov tuab ntawm lub lens, txo qhov zoo ntawm lub lens, tib lub sijhawm, ua rau lub lens ntau ntshiab thiab ci, tsis yooj yim rau disperse rainbow grain. Nws pom tias ntxiv cyclic sulfide resin rau hauv cov khoom siv lens tuaj yeem txhim kho qhov refractive index ntawm lub lens, tab sis ntau dhau cyclic sulfide resin yuav ua rau txo qis ntawm lub teeb transmittance thiab cov khoom tawg. Los ntawm kev tswj hwm cov ntsiab lus ntawm lub nplhaib sulfur resin hauv 1.71KR resin, 1.71 lens ua tiav siab refractive index thiab abbe tus lej thaum ua kom muaj lub teeb transmittance zoo, qis dispersion thiab pom tseeb dua.

1.56 Ib Lub Zeem Muag HMC
Lub lens, tseem hu ua lub iav nruab nrab, yog lub chaw pleev xim tom qab kev teeb tsa, tsim nyog rau kev clamping hauv lub thav duab iav, yog li nws hu ua lub iav nruab nrab. Nws cov duab tuaj yeem ua kab rov tav, ntsug, yog qhov yooj yim, yooj yim rau kev teeb tsa.
Kev Faib Tawm: Cov tsom iav tuaj yeem muab faib ua plaub hom raws li cov ntaub ntawv sib txawv:
Resin lens tshwj xeeb lens qhov chaw lens iav lens
