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

1.49 Ib Lub Zeem Muag UC
Tus nqi refractive index ntawm lub lens, 1.49, 1.56, 1.60, 1.67, 1.71, 1.74 ntawm lub cim sab saud ntawm lub lens txhais tau tias tus nqi refractive index ntawm lub lens. Rau cov tsom iav myopic, tus nqi refractive index ntawm lub lens siab dua, qhov ntug ntawm lub lens nyias dua, vim tias lwm yam kev teeb tsa zoo ib yam.

CR39 Cov tsom iav dub
Cov tsom iav dub yog ib yam khoom siv los saib xyuas qhov muag kom tiv thaiv kev puas tsuaj rau tib neeg lub qhov muag los ntawm lub hnub ci muaj zog. Nrog kev txhim kho ntawm tib neeg cov khoom siv thiab kab lis kev cai, cov tsom iav dub tuaj yeem siv ua cov khoom siv tshwj xeeb rau kev zoo nkauj lossis tus kheej tus cwj pwm.

1.74 MR-174 FSV High Index HMC optical lenses
Feem ntau, thaum peb tham txog qhov ntsuas ntawm cov iav resin, nws yog los ntawm 1.49 - 1.56 - 1.61 - 1.67 - 1.71 - 1.74. Yog li ntawd, tib lub zog, 1.74 yog qhov nyias tshaj plaws, lub zog siab dua, qhov pom tseeb dua qhov cuam tshuam.
-
1.67 MR-7 FSV High Index HMC optical lenses
1.67 index lens feem ntau muaj ob hom khoom siv, MR-7 khoom siv thiab MR-10 khoom siv.
Tab sis cov khoom siv MR-7 yog cov khoom siv dav dua thiab paub zoo tshaj plaws dua li cov khoom siv MR-10.
-
1.61 MR-8 FSV High Index HMC optical lenses
1.61 index lens feem ntau cais ob hom, 1.61 MR-8 lens thiab 1.61 Acrylic lens.
1.61 MR-8 lens yuav xis dua thaum hnav, vim nws zoo Abbe Value: 41.
-
1.59 Polycarbonate HMC Optical lenses
Cov iav resin feem ntau yog cov khoom siv thermal solid, uas yog, cov khoom siv raw yog kua, thiab cov iav khov kho tau tsim tom qab cua sov. Cov iav PC, tseem hu ua "space lenses", "cosmic lenses", hu ua polycarbonate, yog cov khoom siv thermoplastic.
-
1.56 Bifocal Flat top / Round Top / Blended HMC optical lenses
Cov tsom iav bifocals yog cov tsom iav uas muaj ob qho chaw kho thiab feem ntau yog siv rau kev kho qhov muag presbyopia. Thaj chaw uas cov tsom iav bifocals kho qhov pom kev deb hu ua thaj chaw pom kev deb, thiab thaj chaw uas kho qhov pom kev ze hu ua thaj chaw pom kev ze thiab thaj chaw nyeem ntawv. Feem ntau, thaj chaw deb loj dua, yog li nws kuj hu ua daim tseem ceeb, thiab thaj chaw ze me dua, hu ua daim seem.
-
1.56 Porgressive HMC optical lenses
Lub tsom iav progressive yog lub tsom iav uas muaj ntau lub focal length, txawv ntawm cov tsom iav nyeem ntawv ib txwm muaj thiab cov tsom iav nyeem ntawv bifocal. Cov tsom iav progressive tsis ua rau lub qhov muag nkees thaum siv cov tsom iav bifocal lengths, thiab tsis muaj kab pom tseeb ntawm ob lub focal lengths. Nws yooj yim hnav thiab muaj tsos zoo nkauj, thiab maj mam dhau los ua qhov kev xaiv zoo tshaj plaws rau cov neeg uas muaj presbyopia.
