Qhov txawv ntawm stereoscopic microscope thiab dog dig optical microscope
Ib qho yooj yim optical microscope yog ib qho cuab yeej kho qhov muag. Yav dhau los, cov tshuab microscopes yooj yim tsuas yog tsim los ntawm ob peb lub lo ntsiab muag, thaum tam sim no siv cov tshuab microscopes 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: cov cuab yeej siv tshuab thiab lub tshuab kho qhov muag. Ob qhov no tau ua haujlwm zoo los ua lub luag haujlwm ntawm lub tshuab tsom.
Stereomicroscope
Lub hauv paus ntsiab lus thiab cov qauv ntawm stereoscopic microscope yog tsim los ntawm lub hom phiaj tseem ceeb ntawm lub lens. Tom qab kev yees duab ib yam khoom, ob lub teeb ntawm lub teeb yog 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 lub volumetric kaum. Feem ntau, lub kaum sab xis saib yog 12 degrees txog 15 degrees. Tom qab kev yees duab los ntawm txhua lub qhov muag, qhov kev hloov pauv loj yog tau los ntawm kev hloov qhov kev ncua deb ntawm pawg lens nruab nrab. Los ntawm kev siv ob txoj hauv kev kho qhov muag, sab laug thiab sab xis kab teeb nyob rau hauv binocular lens raj tsis yog tib yam, Nws muaj lub kaum ntse ntse, muab cov duab peb sab rau sab laug thiab sab xis. Nws qhov tseem ceeb muaj ob lub raj microscopes muab tso rau ntawm ib sab, nrog rau qhov muag pom ntawm ob lub raj tsim qhov kev xav tau tsim thaum tib neeg saib ib qho khoom nrog lawv lub koob yees duab, yog li tsim cov duab peb sab.
Qhov txawv ntawm ob:
Txoj kev siv ntawm stereoscopic microscope zoo ib yam li cov khoom siv kho qhov muag zoo tib yam, tab sis nws yooj yim dua. Qhov sib txawv tseem ceeb ntawm ob yog tias cov khoom siv tshuaj ntsuam xyuas lub tshuab hluav taws xob tsis tas yuav tsum tau ua rau hauv ib thooj; Lub stereoscopic microscope txiav lub rooj yog tsau ncaj qha rau ntawm daim iav puag thiab nruab nrog ib tug dub thiab dawb ob sab phaj los yog iav phaj. Tus neeg teb xov tooj tuaj yeem xaiv raws li cov khoom thiab cov kev xav tau ntawm kev tshuaj xyuas daim iav; Cov duab ntawm lub stereoscopic microscope yog upright, ua rau nws yooj yim rau paub qhov txawv orientation thaum lub sij hawm ua hauj lwm anatomical. Lub hom phiaj ntawm lub tshuab tsom iav stereoscopic tsuas yog ib qho xwb, thiab nws qhov kev nthuav dav tuaj yeem hloov kho tsis tu ncua los ntawm kev tig cov kauv.
