Feem ntau MR-7 siv los ua cov iav tsom iav siab, nrog rau qhov ntsuas refractive ntawm 1.677. Txaus siab rau qhov zoo dua li yav dhau los, txawm tias muaj cov lej siab. Piv rau cov iav tsom iav ib txwm muaj, MR-7 nyias dua thiab muaj kev nyab xeeb dua. MR-7 kuj yog cov khoom siv uas muaj cov nyhuv dyeing zoo dua tam sim no. Qee cov iav tsom iav xim thiab cov tsom iav myopia yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv no.
Kev Taw Qhia Txog Kev Tsim Khoom
Cov khoom siv MR-7 thiab MR-10 muaj qhov refractive index txog li 1.67, thiab cov iav siab tsim tau lub teeb dua thiab nyias dua. Qhov kub ntawm MR-7 yog 85 degrees, thiab MR-10 yog 100 degrees. Ob qho tib si MR-7 thiab MR-10 yog cov khoom siv iav refractive index 1.67. MR-7 yooj yim dua rau zas dua li MR-10, yog li MR-7 zoo dua rau cov tsom iav myopia, lossis cov iav zam. Cov iav MR-10 muaj qhov nyuaj dua, tiv taus kub zoo dua, thiab ua tau zoo dua. Lawv feem ntau siv rau hauv cov chaw ua haujlwm thiab kev ua cov iav tshwj xeeb.
Feem ntau ntawm cov tsom iav niaj hnub no yog ua los ntawm cov iav resin. Feem ntau, yog tias tsis tiv taus cua sov, zaj duab xis ntawm qhov chaw ntawm lub lens yuav tawg, uas yog tshwm sim los ntawm kev nthuav dav thermal. Piv nrog rau zaj duab xis reflective ntawm lub lens, qib ntawm kev nthuav dav thermal ntawm cov khoom siv hauv paus yog qhov loj heev, thiab qib ntawm kev nthuav dav thermal ntawm zaj duab xis reflective thiab cov khoom siv hauv paus yog txawv, thiab zaj duab xis yuav tawg.
Raws li qhov kev xav no, MR-10 zam tau qhov teeb meem no txij thaum pib tsim cov khoom siv, thiab los ntawm kev txhim kho tas mus li, nws tau dhau los ua cov khoom siv uas muaj kev tiv taus cua sov zoo thiab cov coefficient nthuav dav thermal qis.
Ua ntej, thaum qhov kub nce ntxiv, qhov coefficient ntawm thermal expansion feem ntau yuav nce ntxiv, tab sis qhov coefficient ntawm thermal expansion ntawm MR-10 yog 25% me dua li ntawm cov khoom siv dav dav 1.67. Piv nrog rau cov khoom siv dav dav 1.67, MR-10 muaj qhov thermal expansion tsawg dua, tsis yooj yim tawg, thiab tsis tshua muaj kev cuam tshuam los ntawm cua sov.
Qhov thib ob, thaum qhov kub yog 95 ° C, ntau qhov tawg tshwm sim ntawm lub lens 1.67 ib txwm muaj, thaum MR-10 tsis cuam tshuam kiag li.
