Yuav ua li cas xam qhov magnification ntawm lub tshuab microscope?
Ntau lub chaw soj nstuam tau siv lub tshuab tsom iav, 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?
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 stereoscopic microscope eyepiece yog 10 zaug, lub zoom ntau yam yog 0.7X-4.5X, thiab lub hom phiaj ntxiv yog 2 X. Optical magnification ntawm lub tshuab ntsuas no yog 10 npaug 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. Tag nrho optical magnification ntawm no stereoscopic 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 kev teeb tsa ntawm lub stereoscopic microscope saum toj no, 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, qhov tsawg kawg nkaus digital magnification yog 0.7 zaug 2 zaug 1 zaug 72, uas yog 100.8 zaug. Qhov siab tshaj plaws digital magnification yog 4.5 zaug 2 zaug 1 zaug 72, uas yog 648 zaug. Qhov ntau ntawm digital magnification yog 100.8 txog 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=hom phiaj 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 ntsuas metallographic, lub tshuab kuaj kab mob lom neeg, thiab lwm yam.
