Cov khoom siv ntawm lub lens
1. Cov iav yas. Cov iav yas feem ntau muab faib ua peb hom: cov iav resin, cov iav PC, thiab cov iav acrylic. Nws muaj qhov zoo ntawm lub teeb thiab tsis tawg. Piv nrog cov iav iav, nws muaj kev ua tau zoo tiv thaiv ultraviolet zoo dua. Tab sis cov iav yas tsis zoo tiv taus kev hnav, ntshai kev cuam tshuam, thaum rov zoo, yuav tsum tau them sai sai rau.
2. Lub iav iav. Kev ua haujlwm kho qhov muag ntawm lub iav iav ruaj khov, tsis yooj yim rau deform, tab sis nws tsis yooj yim tawg, kev ua haujlwm nyab xeeb tsis txaus, hauv qhov no, kev ua haujlwm nyab xeeb ntawm lub iav iav uas tau tsim kho dua tshiab yuav siab dua.
3. Cov iav tsom iav polarizing. Cov iav tsom iav polarized feem ntau yog cov iav uas ua los ntawm kev siv lub teeb polarization. Nws tuaj yeem ua rau pom kev meej dua thiab txiav cov teeb ci ntsa iab sab nraud ntawm lub iav. Nws yog cov iav siv dav hauv kev ua lag luam niaj hnub no.
4. Cov iav hloov xim. Cov iav hloov xim yog cov iav uas tsim cov xim sib txawv nyob ntawm seb lub teeb hloov li cas. Nws tso cai rau lub qhov muag hloov kho rau cov chaw teeb pom kev sib txawv, thiab cov tsom iav uas muaj cov iav hloov xim kuj paub tias yog cov tsom iav yooj yim tshaj plaws rau myopia.
Kev Taw Qhia Txog Kev Tsim Khoom
Tus refractive index yog hais txog tus refractive index ntawm lub lens, thiab qhov siab dua tus refractive index, qhov nyias dua lub lens. Tus refractive index feem ntau yog 1.49, 1.56, 1.61, 1.67, 1.74.
Yuav tsum txiav txim siab seb qhov refractive index puas tsim nyog raws li qib, qhov deb ntawm tus menyuam qhov muag thiab qhov loj ntawm lub thav duab. Feem ntau, qhov degree siab dua, qhov refractive index ntawm lub lens yuav siab dua, yuav ua rau lub lens zoo li nyias dua. Ib yam li ntawd, yog tias qhov deb ntawm tus menyuam qhov muag me me thiab lub thav duab loj, koj yuav tsum xaiv lub lens refractive index siab kom ua rau lub lens nyias dua. Ntawm qhov tod tes, yog tias lub thav duab me me thiab qhov deb ntawm tus menyuam qhov muag loj, tsis tas yuav siv lub lens index siab.
