Lub microscope lub magnification factor ua haujlwm li cas?
Ntau lub chaw soj nstuam tau siv cov tshuab microscopes, 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 xam qhov magnification ntawm microscopes?
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, cia peb muab piv txwv: thaum qhov magnification ntawm lub stereo microscope eyepiece yog 10 lub sij hawm, qhov magnification ntau ntawm qhov sib txawv ntawm qhov magnification yog 0.7X-4.5X, thiab qhov ntxiv lub hom phiaj yog 2 X. Optical magnification ntawm lub tshuab ntsuas no yog 10 npaug ntawm 0.7 npaug 2, uas ua rau qhov kev nthuav dav tsawg ntawm 14 npaug thiab qhov loj ntawm 10 npaug 4.5 npaug 2, uas yog 90 zaug. Yog li ntawd, tag nrho cov optical magnification ntawm lub tso suab microscope yog 14 txog 90 zaug. 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, yog tias qhov loj ntawm lub monitor yog 17 ntiv tes thiab 1/3 lub koob yees duab microscope siv, qhov kev nthuav dav digital ntawm lub koob yees duab microscope yog 72 npaug piv rau cov lus hauv qab no. Cov mis laij lej rau digital magnification ntawm lub tshuab tsom iav yog raws li hauv qab no: raws li kev teeb tsa ntawm lub tso suab tso suab, 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 1 (yog tias lub koob yees duab eyepiece tsis muaj ntau, nws tsis tas yuav suav nrog hauv kev suav). Raws li cov qauv: lub hom phiaj X lub koob yees duab eyepiece magnification X digital magnification, digital magnification yog 0.7 zaug 2 zaug 1 zaug 72, uas yog 100.8 npaug, thiab cov magnification yog 4.5 zaug 2 zaug 1 zaug 72, yog 648x. Qhov ntau ntawm digital magnification yog 100.8 npaug rau 648 zaug.
Hauv qhov no, ob qho qauv yuav tshwm sim:
1. Tag nrho optical magnification=magnification ntawm lub qhov muag X magnification ntawm lub hom phiaj lens
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.
