MR-174 yog lub hnub qub ntawm MR series tsev neeg, nrog lub siab tshaj plaws refractive index nyob rau hauv lub series, ua rau nws lub qhov kawg nyias thiab lub teeb lens.
Cov khoom siv MR-174 muaj qhov ntsuas tsis pom kev ntawm 1.74, AbbeTus nqintawm 32, thiab kub distortion kub ntawm 78 ° C.Thaum ua tau zoo heev lightness thiab thinness, nws kuj siv "Do Green" cov khoom muab los ntawm cov khoom cog.
MR-174 yog ib tug neeg sawv cev ntawm high-refractive index khoom nyob rau hauv lub ntiaj teb no lens lag luam.Yog li ntawd, cov neeg siv khoom uas muaj qib siab dua, lossis cov neeg siv khoom uas ua raws li nyias thiab lub teeb ua haujlwm ntawm cov lo ntsiab muag thiab txhawj xeeb txog kev tiv thaiv ib puag ncig, dav yuav MR.Lenses ua los ntawm -174 khoom.
Qhuav Taw Qhia
Sib piv ntawm 1.74 thiab 1.67:
1.67 thiab 1.74 ob leeg sawv cev rau qhov ntsuas qhov ntsuas ntawm lub lens, thiab qhov sib txawv tshwj xeeb yog nyob rau hauv plaub yam nram qab no.
1. Thickness
Qhov siab dua qhov Performance index ntawm refraction ntawm cov khoom, lub zog muaj peev xwm rau refract teeb meem teeb.Qhov siab dua qhov refractive index, lub thinner lub thickness ntawm lub lens, uas yog, lub thickness ntawm qhov chaw ntawm lub lens yog tib yam, tib degree ntawm tib cov khoom, lub ntug ntawm lub lens nrog siab refractive index yog thinner dua. ntug ntawm lub lens nrog qis refractive index.
Qhov ntawd yog hais tias, nyob rau hauv cov ntaub ntawv ntawm tib degree, lub lens nrog ib tug refractive index ntawm 1.74 yog nyias dua li ib lub lens nrog ib tug refractive index ntawm 1.67.
2. Nyhav
Siab dua refractive index, thinner lo ntsiab muag, thiab sib dua lo ntsiab muag rau ib tug ntau xis hnav.
Qhov ntawd yog hais tias, nyob rau hauv cov ntaub ntawv ntawm tib degree, lub lens nrog ib tug refractive index ntawm 1.74 yog sib dua li ib lub lens nrog ib tug refractive index ntawm 1.67.
3. AbTus nqi(Dispersion coefficient)
Feem ntau hais lus, qhov siab dua qhov refractive index ntawm lub lens, qhov pom tseeb dua tus qauv zaj sawv ntawm ntug thaum saib cov khoom.Qhov no yog qhov tshwm sim dispersion ntawm lub lens, uas feem ntau qhia los ntawm AbbeTus nqi(Dispersion coefficient).Qhov siab dua AbbeTus nqi, zoo dua.Yam tsawg kawg nkaus AbbeTus nqintawm lo ntsiab muag rau tib neeg hnav tsis tuaj yeem qis dua 30.
Txawm li cas los xij, tus nqi Abbe ntawm ob lub lens refractive no tsis siab, tsuas yog hais txog 33.
Feem ntau, qhov siab dua qhov refractive index ntawm cov khoom, qhov qis dua tus nqi Abbe.Txawm li cas los xij, nrog kev kho dua tshiab ntawm cov khoom siv lens, txoj cai no maj mam tawg.
4. Nqe
Qhov siab dua qhov refractive index ntawm lub lens, tus nqi kim dua.Piv txwv li, 1.74 lo ntsiab muag ntawm tib hom yuav ntau dua5piv tus nqi ntawm 1.67.
