Dab tsi yog qhov magnification ntawm electron microscope
Lub magnification ntawm lub tshuab tsom xam yog hais txog cov khoom ntawm qhov loj ntawm lub qhov muag thiab lub hom phiaj lens, thiab qhov kev nthuav dav yog qhov ntev lossis qhov dav ntawm cov duab duab. Yog hais tias qhov loj ntawm lub qhov muag yog 10 npaug thiab qhov loj ntawm lub hom phiaj lens yog 40 npaug, qhov loj ntawm lub tshuab tsom iav yog ═10 × 40═400 zaug.
Muaj ob lub ntsiab lus ntawm kev nthuav dav tag nrho, ib qho yog optical magnification thiab lwm qhov yog digital magnification (digital magnification tsuas yog koom nrog thaum lub cuab yeej duab txuas nrog).
1. Optical magnification yog hais txog qhov kev nthuav dav ntawm cov khoom peb soj ntsuam los ntawm lub tshuab tsom iav qhov muag tom qab tau nthuav dav. Txoj kev suav ntawm optical magnification yog qhov yooj yim, uas yog, lub hom phiaj lens ntau * eyepiece ntau.
Piv txwv li, nyob rau hauv kev xam ntawm qhov magnification ntawm lub stereo microscope, lub hom phiaj lens ntawm ib tug nruam zoom stereo microscope feem ntau yog 0.7-4.5 zaug, thiab nyob rau hauv cov ntaub ntawv ntawm ib tug 10 zaug eyepiece, tag nrho qhov loj ntawm lub tshuab ntsuas no yog 7-45 zaug.
Kev suav cov tshuab kuaj kab mob lom neeg thiab cov kab mob metallographic yog yooj yim dua. Lub hom phiaj ntawm lub hom phiaj yog 4 zaug, 10 zaug, 40 zaug, thiab 100 zaug. Qhov kev teeb tsa ib txwm ntawm eyepieces yog 10 zaug, thiab tseem muaj 16 zaug thiab 20 zaug. Tag nrho cov magnification tuaj yeem tau txais los ntawm kev muab nws los ntawm kev nthuav dav ntawm lub hom phiaj lens.
