Yuav ua li cas txiav txim siab yuav ua li cas kom loj hlob ib lub microscope?
Ntau lub chaw soj nstuam siv lub tshuab ntsuas tshuab, tab sis lawv tsis paub txog cov kev paub txog kev siv tshuab microscopes. Lawv tsuas paub yuav ua li cas khiav lawv, tab sis tej zaum yuav tsis meej meej txog qee qhov kev paub yooj yim. Yog li hnub no peb yuav tham txog yuav ua li cas lub magnification ntawm microscopes xam?
Tej zaum qee tus neeg yuav hais tias qhov no tsis yog qhov teeb meem yooj yim heev, tab sis qhov tseeb nws tseem nyuaj me ntsis.
Ua ntej ntawm tag nrho cov, cia peb muab piv txwv: thaum lub magnification ntawm lub stereo microscope eyepiece yog 10x, lub zoom ntau yam ntawm lub variable magnification lub cev yog 0.7X-4.5X, thiab lub hom phiaj ntxiv yog 2X. Optical magnification ntawm lub tshuab ntsuas no yog 10 npaug ntawm 0.7 npaug 2, ua rau qhov kev nthuav dav yam tsawg kawg nkaus ntawm 14 npaug. Qhov siab tshaj plaws yog 10 npaug 4.5 npaug 2, uas sib npaug 90 npaug. Yog li ntawd, tag nrho cov optical magnification ntawm lub stereo microscope yog li ntawm 14 npaug rau 90 zaug. Ntawm chav kawm, qhov no tsuas yog qhov tseeb magnification ntawm lub microscope mainframe. Tom ntej no yog qhov kev nthuav dav digital ntawm lub tshuab microscope.
Piv txwv li, yog tias qhov loj ntawm tus saib yog 17 ntiv tes thiab 1/3 lub koob yees duab microscope siv, qhov kev nthuav dav digital ntawm lub koob yees duab microscope raws li qhia hauv 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 sab saum toj, qhov sib txawv ntawm qhov sib txawv yog 0.7X-4.5X, thiab lub hom phiaj ntxiv yog 2X. Lub koob yees duab eyepiece yog teem rau 1 (yog tias lub koob yees duab eyepiece tsis muaj qhov sib npaug, nws tsis tas yuav suav nrog hauv kev suav). Raws li cov qauv: lub hom phiaj lens X lub koob yees duab eyepiece magnification X digital magnification, qhov tsawg kawg nkaus digital magnification yog 0.7 zaug 2 zaug 1 zaug 72, uas sib npaug 100.8 npaug. Qhov siab tshaj plaws digital magnification yog 4.5 npaug 2 zaug 1 zaug 72, uas sib npaug 648 npaug. Yog li, qhov ntau ntawm digital magnification yog los ntawm 100.8 npaug rau 648 zaug.
Hauv qhov no, ob lub qauv yuav tshwm sim:
1. Optical tag nrho magnification= eyepiece magnification X lub hom phiaj magnification
2. Digital tag nrho magnification=objective lens X lub koob yees duab eyepiece magnification X digital magnification
Cov mis no haum rau txhua lub tshuab tsom, txawm tias nws yog lub tshuab microscope, ib lub tshuab kuaj kab mob lom, thiab lwm yam.
