Puas muaj qhov sib txawv loj ntawm lub stereo microscope thiab lub tshuab kho qhov muag zoo tib yam?
Ordinary optical microscope yog qhov ntsuas qhov muag pom tseeb. Tej yam yooj yim microscopes yav dhau los tsuas muaj ob peb lo ntsiab muag xwb, thaum lub tshuab microscopes siv niaj hnub no muaj ib txheej ntawm lo ntsiab muag. Ordinary optical microscopes feem ntau tuaj yeem nthuav cov khoom los ntawm 1500-2000 zaug. Cov qauv ntawm lub tshuab kho qhov muag zoo tib yam tuaj yeem muab faib ua ob ntu: ib qho yog cov cuab yeej siv tshuab thiab lwm qhov yog qhov kho qhov muag. Tsuas yog thaum ob ntu no sib koom ua ke zoo tuaj yeem ua lub tshuab tsom rau nws lub luag haujlwm.
Stereomicroscope
Stereo microscope txoj cai thiab stereo microscope qauv yog tsim los ntawm lub hom phiaj tseem ceeb ntawm lub lens. Tom qab ntsuas qhov khoom, ob lub teeb teeb pom kev sib cais los ntawm ob pawg ntawm lub hom phiaj nruab nrab lub ntsiab lus, tseem hu ua zoom lo ntsiab muag, thiab tsim ib lub kaum ntse ntse hu ua stereoscopic lub kaum ntse ntse. Feem ntau, nws yog 12 degrees - -15 degrees, tom qab ntawd ua duab los ntawm cov eyepieces, nws qhov kev hloov pauv loj yog tau los ntawm kev hloov qhov kev ncua deb ntawm pawg lens nruab nrab, siv ob txoj kev kho qhov muag, sab laug thiab sab xis kab nyob hauv binocular raj tsis yog sib npaug, tab sis muaj qee qhov clip kaum los muab cov duab peb sab rau sab laug thiab sab xis. Nws yog qhov tseem ceeb ntawm ob lub lens ib leeg lub raj tsom iav tso rau ntawm ib sab, thiab cov axes ntawm ob lub raj tsim ib lub kaum sab xis pom zoo ib yam li qhov tsim thaum tib neeg pom ib yam khoom nrog lub koob yees duab, yog li tsim cov duab peb sab stereoscopic.
Qhov txawv ntawm ob:
Txoj kev siv lub tso suab microscope zoo ib yam li qhov zoo tib yam optical microscope, tab sis nws yooj yim dua. Qhov sib txawv tseem ceeb ntawm ob yog tias: cov khoom siv tsom iav ntawm lub stereo microscope lauj kaub tsis tas yuav tsum tau ua rau hauv ib daim; lub rooj txiav ntawm stereo microscope yog tsau ncaj qha rau ntawm daim iav. Nyob rau hauv lub rooj zaum, nws yog nruab nrog dub thiab dawb ob chav panels los yog iav panels, tus neeg teb xov tooj tuaj yeem xaiv raws li cov khoom thiab cov kev xav tau ntawm kev tshuaj xyuas lub tshuab ntsuas; Cov duab ntawm lub stereo microscope yog upright, uas yog yooj yim rau kev paub qhov txawv cov kev taw qhia thaum lub sij hawm dissection lag luam, thiab tsuas muaj ib lub hom phiaj ntawm lub stereo microscope, nws magnification yuav tsum tau kho tsis tu ncua los ntawm rotating lub adjusting ntsia hlau.
