Rov nkag siab txog qhov ua tau zoo magnification ntawm microscope

Kev sib raug zoo ntawm qhov ua tau zoo magnification (M) ntawm lub tshuab microscope thiab cov lej aperture (NA) ntawm lub hom phiaj lens tuaj yeem qhia tau tias: 550NA; tau ntev lawm, cov neeg siv tshuab tsom iav tau ua raws li qhov kev sib raug zoo no. Txawm li cas los xij, VanderVoort hauv nws phau ntawv " Phau ntawv Metallography - Cov Ntsiab Lus thiab Kev Coj Ua tau taw qhia tias cov qauv saum toj no tau muab los ntawm kev soj ntsuam cov khoom zoo sib xws nrog lub qhov muag zoo tagnrho, yog li tsis txhob ua raws li dogma. Qhov tseeb, kev daws teeb meem. Tsis yog tsuas yog cuam tshuam nrog kev daws teeb meem ntawm lub hom phiaj lens Related, tab sis kuj tseem cuam tshuam rau qhov sib piv ntawm cov duab khoom. Tsis tas li ntawd, cov teeb pom kev zoo, kev nthuav dav, lub hom phiaj lens zoo, thiab kev soj ntsuam txhua yam yuav cuam tshuam rau qhov sib piv ntawm cov duab duab, thiab Yog li tseem cuam tshuam rau kev daws teeb meem, nws tau taw qhia tias txhawm rau kom tau txais qhov kev daws teeb meem siab tshaj plaws, qhov ua tau zoo tshaj plaws yuav tsum yog kwv yees li 4 zaug nyob rau hauv cov xwm txheej zoo tshaj plaws, uas yog, M≈2200NA; tib lub sijhawm, nws yog qhov tsim nyog kiag li. siv photomicrographs nrog magnifications ntawm 4000 × los yog siab dua.
