Yuav ua li cas lub magnification ntawm lub microscope xam?
Tag nrho cov optical magnification=qhov magnification ntawm eyepiece X lub magnification ntawm lub hom phiaj lens (yog hais tias muaj ib tug ntxiv lub hom phiaj lens, lub hom phiaj ntxiv lens yuav tsum tau suav).
Tag nrho cov magnification=lub hom phiaj lens X lub koob yees duab eyepiece magnification X digital magnification (yog tias muaj lub hom phiaj ntxiv, lub hom phiaj lens ntxiv yuav tsum suav nrog)
Siv lub stereo microscope ua piv txwv: thaum qhov loj ntawm lub stereo microscope eyepiece yog 10 zaug, qhov zoom ntau ntawm lub cev zoom yog: 0.7X-4.5X, thiab lub hom phiaj ntxiv yog: 2X. Tom qab ntawd nws qhov kev nthuav dav yog: 10 npaug 0.7 npaug 2 kom tau txais qhov kev nthuav dav yam tsawg kawg nkaus ntawm lub tshuab tsom iav no: 14 npaug, tom qab ntawd qhov siab tshaj plaws yog: 10 npaug 4.5 npaug 2 sib npaug 90 npaug, tom qab ntawd qhov muag tag nrho ntawm lub tso suab microscope Qhov magnification yog 14. ua 90x.
Yog li dab tsi yog qhov digital magnification xam ntawm lub tshuab tsom iav? Piv txwv li, yog tias qhov loj ntawm cov zaub yog 17 ntiv tes thiab 1/3 lub koob yees duab microscope siv, ces qhov kev nthuav dav digital ntawm lub koob yees duab microscope piv rau cov lus hauv qab no yog: 72 zaug. Cov mis rau kev suav cov digital magnification ntawm lub tshuab tsom iav yog: raws li kev teeb tsa ntawm lub tso suab tso suab saum toj no, lub cev zoom yog 0.7X-4.5X, thiab lub hom phiaj ntxiv yog 2X. Lub koob yees duab eyepiece yog 1 (yog tias lub koob yees duab eyepiece tsis muaj ntau yam, nws tsis tas yuav ntxiv rau kev suav). Raws li cov qauv: lub hom phiaj lens X lub koob yees duab eyepiece magnification X digital magnification, qhov tsawg kawg nkaus magnification ntawm digital magnification yog: 0.7 zaug 2 zaug 1 zaug 72 yog sib npaug rau: 100.8 npaug, qhov siab tshaj plaws magnification ntawm digital magnification yog : 4.5 x 2 x 1 x 72=648 times. Qhov ntau ntawm digital magnification yog 100.8 npaug rau 648 zaug.
