1.56 Ib Lub Zeem Muag HMC

Kev Piav Qhia Luv:

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 yog ib qho hydrocarbon (hydrocarbon) exudate los ntawm ntau yam nroj tsuag, tshwj xeeb tshaj yog conifers. Vim nws cov qauv tshuaj tshwj xeeb thiab tuaj yeem siv ua cov xim latex thiab cov nplaum no muaj nqis. Nws yog ib qho sib xyaw ntawm cov tshuaj molecular siab, yog li nws muaj cov ntsiab lus melting sib txawv. Resins tuaj yeem muab faib ua cov resins ntuj thiab cov resins hluavtaws. Muaj ntau hom resin, siv dav hauv kev lag luam lub teeb thiab kev lag luam hnyav, hauv lub neej txhua hnub kuj tuaj yeem pom, xws li yas, iav resin, xim thiab lwm yam. Resin lens yog lub lens tom qab ua tshuaj lom neeg thiab polishing nrog resin ua cov khoom siv raw.

Kev Taw Qhia Txog Kev Tsim Khoom

1.56 yog qhov ntsuas refractive ntawm lub lens

Qhov siab dua qhov refractive index ntawm lub lens, qhov nyias dua lub lens ntawm tib degree. Feem ntau cov neeg siv cov lens nrog refractive index ntawm 1.56. Yog tias qhov degree siab dhau, cov lens nrog refractive index ntawm 1.56 yuav tuab heev, yog li peb yuav tsum xaiv cov lens nrog refractive index loj dua. Kev txheej yog txheej lub lens nrog ib txheej khoom uas muaj ntau yam haujlwm sib txawv. qee qhov

Zaj duab xis tiv thaiv ultraviolet, qee qhov tuaj yeem ua si qhov cuam tshuam ntawm kev nce qhov kev xa tawm ntawm lub lens, yog cov tsom iav meej dua.

Feem ntau, thaum xaiv cov tsom iav, nws raug pom zoo tias qhov ntsuas refractive yuav tsum tsis txhob siab dhau lossis qis dhau, vim tias cov tsom iav uas muaj qhov ntsuas refractive tsis tsim nyog yuav ua rau lub nra hnyav rau cov neeg mob lub qhov muag. Cov tsom iav uas muaj 1.56 muaj qhov ntsuas refractive qis, uas feem ntau haum rau cov neeg mob uas muaj myopia qis lossis myopia nruab nrab. Nws raug pom zoo tias cov neeg uas muaj myopia nruab nrab thiab qis xaiv cov tsom iav uas muaj qhov ntsuas refractive ntawm 1.50 thiab 1.60.

Qhov ntsuas refractive muaj feem cuam tshuam nrog qhov tuab ntawm lub lens, tab sis thaum xaiv lub lens, koj yuav tsum tsis txhob tsuas yog saib qhov ntsuas refractive xwb, tab sis kuj yuav tsum piv qhov hnyav tshwj xeeb ntawm lub lens, kev xa hluav taws xob, kev tiv thaiv UV thiab lwm yam kom nkag siab zoo.
