Yuav ua li cas koj tau txais qhov magnification ntawm lub microscope?
Ntau lub chaw soj nstuam tau siv lub tshuab ntsuas ntsuas, tab sis lawv tsis paub txog kev paub txog kev siv tshuab microscopes, tsuas yog paub yuav ua li cas khiav lawv, tab sis lawv yuav tsis meej meej txog qee qhov kev nkag siab yooj yim. Yog li hnub no peb yuav tham txog yuav ua li cas xam qhov magnification ntawm microscopes.
Qee tus neeg yuav hais tias qhov no tsis yog ib lo lus nug yooj yim heev, tab sis nws yog qhov nyuaj me ntsis.
Ua ntej tshaj plaws, cia peb ua ib qho piv txwv: thaum qhov loj ntawm lub qhov muag ntawm lub stereoscopic microscope 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 ua kom pom tseeb yog: 10 npaug 0.7 npaug 2, thiab qhov kev nthuav dav qis ntawm lub tshuab tsom iav no yog: 14 npaug, thiab qhov loj ntawm zui yog: 10 npaug 4.5 npaug 2 sib npaug 90 npaug, yog li tag nrho qhov kev nthuav dav ntawm lub koob yees duab stereoscopic. yog 14x90x. Ntawm chav kawm, qhov no tsuas yog qhov tseeb magnification ntawm lub microscope party. Tom ntej no yog qhov kev nthuav dav digital ntawm lub tshuab microscope.
Piv txwv li, qhov loj ntawm lub monitor yog 17 ntiv tes, thiab 1/3 ntawm lub koob yees duab microscope yog siv, yog li qhov kev nthuav dav digital ntawm lub koob yees duab microscope yog 72 zaug piv nrog cov lus hauv qab no. Cov mis rau kev xam cov digital magnification ntawm lub microscope yog: raws li lub configuration ntawm lub stereoscopic microscope saum toj no, lub 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 yuav tsum tsis txhob muab ntxiv rau hauv kev suav). Raws li cov qauv: lub hom phiaj lens x lub koob yees duab eyepiece magnification x digital magnification, qhov me me ntawm digital magnification zui yog: 0.7 zaug 2 zaug 1 zaug 72 sib npaug: 100.8 npaug, thiab qhov loj ntawm qhov loj ntawm digital magnification zui yog: 4.5 x 2 x 1 x 72 sib npaug: 648 x. Tom qab ntawd qhov ntau ntawm digital magnification yog 100.8 npaug rau 648 zaug.
Hauv qhov no, ob lub qauv yuav tshwm sim:
1. Tag nrho optical magnification=eyepiece magnification x lub hom phiaj magnification.
2. Digital tag nrho magnification=lub hom phiaj lens X lub koob yees duab eyepiece magnification X digital magnification
Cov mis no haum rau txhua lub tshuab tsom, txawm tias nws yog metallographic microscope, biological microscope thiab lwm yam.
