Yuav ua li cas yog tshaj tawm ntawm lub tshuab tsom me me?
Ntau lub chaw soj ntsuam siv cov tshuab raj, tab sis lawv tsis paub txog cov kev paub txog kev muaj feem xyuam ntawm me me. Lawv tsuas paub ua haujlwm lawv, tab sis tsis yog tseeb txog qee yam kev paub yooj yim. Yog li hnub no peb yuav tham txog yuav ua li cas cov kev tshaj lij ntawm lub tshuab tsom iav tau muab xam?
Tej zaum qee tus neeg yuav hais tias qhov no tsis yog teeb meem yooj yim heev, tab sis qhov tseeb nws tseem muaj teeb meem me ntsis.
Ua ntej tshaj plaws, cia muab ib qho piv txwv: Thaum lub ntsiab ntawm lub ntsej muag lub cev yog 10 xoos yog 10 zaug 0.7 zaug Yog li ntawd, tag nrho cov kev kho qhov muag tag nrho ntawm cov kab ke no yog 14 npaug rau 90 zaug. Ntawm chav kawm, qhov no tsuas yog qhov tseeb tiag tiag ntawm lub tshuab tsom mainframe. Tom ntej yog cov digital magnification ntawm lub tshuab tsom.
Piv txwv li, yog tias qhov loj ntawm tus ntsuas yog 17 ntiv thiab 1/3 lub koob yees duab tsom iav siv, lub koob yees duab digital ntawm lub xovtooj ntawm lub rooj hauv qab no yog 72 zaug. Cov mis rau xam cov digital factification yog: raws li lub hom phiaj tseem ceeb yog 1 (yog tias lub koob yees duab lub ntsej muag yog 1 (yog tias lub koob yees duab Eyepiece tsis muaj kev nthuav dav, nws tsis tas yuav muaj nyob hauv kev suav). Raws li cov qauv: Lub hom phiaj X lub koob yees duab lub ntsej muag x digitalification, ntsuas qhov tsawg kawg yog 0.7 zaug hnub tim 12, uas sib npaug 100.8 zaug. Qhov siab tshaj plaws rau kev nthuav dav yog 4.5 zaug 2 zaug sijhawm 12, uas sib npaug ntawm cov digital tshaj plaws yog los ntawm 100.8 zaug rau 648 zaug.
Hauv qhov no, ob tus qauv yuav tshwm sim:
1. Optical Tas Nrho Tshaj Tawm =} Eyepiece magnification X Lub Zog Tshaj Tawm
2. Digital Totalification=Lub Hom Phiaj Lens X Cov Koob Yees Duab X cov yeeb yaj kiab x digital magnification
Cov mis no haum rau txhua lub tshuab ntsuas, txawm tias nws yog lub tshuab tsom qe me me, kev siv roj ntsha, thiab lwm yam
