Qhov sib txawv ntawm lub stereo microscope thiab ib qho zoo tib yam optical microscope
Ib qho yooj yim optical microscope yog qhov ntsuas qhov muag pom tseeb. Yav dhau los, lub tshuab microscopes yooj yim tsuas yog muaj ob peb lo ntsiab muag xwb, tab sis cov tshuab microscopes siv tam sim no suav nrog cov lo ntsiab muag. Ordinary optical microscopes feem ntau tuaj yeem nthuav cov khoom 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 qhov chaw sib koom ua ke zoo tuaj yeem ua lub tshuab tsom iav.
Stereomicroscope
Lub hauv paus ntsiab lus thiab cov qauv ntawm lub stereo microscope yog tsim los ntawm lub hom phiaj tseem ceeb ntawm lub lens. Ob lub teeb ci tom qab kev pom cov khoom raug 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 saib lub kaum ntse ntse, uas feem ntau yog 12 degrees - -15 degrees, thiab tom qab ntawd ua duab los ntawm lawv cov eyepieces. Nws qhov kev hloov pauv loj yog tau los ntawm kev hloov qhov kev ncua deb ntawm pawg lens nruab nrab. Siv txoj kev kho qhov muag ob-channel, sab laug thiab sab xis kab nyob rau hauv binocular raj tsis yog sib npaug, tab sis muaj qee qhov sib tshooj. cov ces kaum, muab cov duab peb sab rau ob lub qhov muag sab laug thiab sab xis. Nws yog qhov tseem ceeb ntawm ob lub tshuab raj ib leeg tso rau ib sab. Lub optical axes ntawm ob lub raj tsim lub kaum sab xis ntawm kev pom tsim thaum tib neeg saib ib yam khoom nrog lub koob yees duab, yog li tsim cov duab stereoscopic hauv qhov chaw peb sab.
Qhov txawv ntawm ob:
Kev siv lub stereomicroscope zoo ib yam li qhov zoo tib yam optical microscope, tab sis yooj yim dua. Qhov sib txawv tseem ceeb ntawm ob yog tias: cov khoom yuav tsum tau soj ntsuam hauv lub stereomicroscope tsis tas yuav tsum tau ua rau hauv lub mount; lub rooj txiav ntawm lub stereomicroscope ncaj qha rau ntawm daim iav. Nws yog mounted rau ntawm lub hauv paus thiab yog nruab nrog ib tug dub thiab dawb ob chav vaj huam sib luag los yog iav phaj. Tus neeg teb xov tooj tuaj yeem xaiv raws li cov khoom thiab cov kev xav tau ntawm lub tshuab tsom. Cov duab ntawm lub stereo microscope yog upright, uas yog yooj yim rau kev txheeb xyuas qhov taw qhia thaum lub sij hawm dissection ua hauj lwm. Lub stereo microscope tsuas muaj ib lub hom phiaj lens xwb. , nws qhov magnification tuaj yeem hloov kho tsis tu ncua los ntawm kev hloov kho cov ntsia hlau.
