Qhov sib txawv ntawm inverted microscope thiab stereo microscope
Cov lus hais yav dhau los yog hais txog txoj hauv kev ntawm microscopy ntawm orthostatic microscope, kev soj ntsuam ntawm ntu tseem ceeb. Thiab inverted microscope yog hloov mus rau biology, tshuaj thiab lwm yam kev lag luam ntawm cov ntaub so ntswg kab lis kev cai, kab lis kev cai ntawm tes, plankton, kev tiv thaiv ib puag ncig, tshuaj xyuas zaub mov thiab lwm yam kev soj ntsuam microscopic. Txawm li cas los xij, cov kev txwv ntawm cov yam ntxwv ntawm cov qauv saum toj no, cov khoom yuav tsum tau tshuaj xyuas yog muab tso rau hauv lub tais petri (los yog kab lis kev cai), uas yuav tsum tau inverted lub hom phiaj tsom iav tsom iav thiab qhov chaw pom muaj qhov ua haujlwm ntev heev, tuaj yeem ncaj qha rau ntawm lub tsom iav tsom iav. petri phaj nyob rau hauv cov khoom yuav tsum tau soj ntsuam rau microscopic kev soj ntsuam thiab kev tshawb fawb. Yog li ntawd, txoj hauj lwm ntawm lub hom phiaj lens, condenser lens thiab lub teeb qhov chaw yog thim rov qab, yog li nws yog hu ua 'inverted microscope'. Vim qhov kev txwv ntawm kev ua hauj lwm nyob deb, lub hom phiaj lens ntawm inverted microscope muaj ib tug magnification ntawm 60 X. Feem ntau, inverted microscopes rau kev tshawb fawb yog nruab nrog 4X, 10X, 20X, thiab 40X theem sib piv lub hom phiaj lo ntsiab muag vim inverted microscopes feem ntau yog siv rau cov xim tsis muaj xim. thiab pob tshab kev soj ntsuam ntawm cov kab mob nyob. Yog tias cov neeg siv muaj kev xav tau tshwj xeeb, lwm yam khoom siv kuj tuaj yeem siv los ua kom tiav cov kev cuam tshuam sib txawv, fluorescence thiab kev soj ntsuam polarization yooj yim. Tam sim no, inverted microscope yog dav siv nyob rau hauv thaj-clamp, transgene ICSI thiab lwm yam teb.
Stereo microscope (Stereo microscope) Stereo microscope, tseem hu ua 'solid microscope' los yog 'anatomical microscope', yog ib hom peb-dimensional kev nkag siab ntawm cov duab zoo ntawm qhov pom kev ntsuas, yog dav siv hauv biology, tshuaj, kev ua liaj ua teb, hav zoov. , kev lag luam thiab marine biology departments. Nws muaj cov yam ntxwv hauv qab no: 1. binocular raj nyob rau sab laug thiab sab xis kab teeb tsis yog sib npaug, tab sis muaj qee lub kaum sab xis - lub cev lub kaum sab xis (feem ntau 12 degrees - 15 degrees), yog li daim duab muaj kev nkag siab peb-dimensional. peb-seem; 2. ntxhw yog upright, yooj yim rau kev khiav lag luam thiab dissection, uas yog vim lub prism hauv qab lub eyepiece rau tus ntxhw inverted lub sake ntawm lub 3. Txawm hais tias lub magnification ntawm cov pa microscope, tab sis qhov kev ua hauj lwm nyob deb heev! 4. loj qhov tob ntawm kev tsom xam, yooj yim rau kev soj ntsuam tag nrho cov txheej ntawm cov khoom yuav tsum tau kuaj xyuas. 5. txoj kab uas hla loj ntawm qhov chaw saib. Cov qauv kho qhov muag tam sim no ntawm lub stereomicroscope yog: los ntawm lub hom phiaj tseem ceeb ntawm lub lens, cov khoom tom qab cov duab ntawm ob lub teeb ntawm lub teeb los ntawm ob pawg ntawm cov hom phiaj nruab nrab ntawm cov lo ntsiab muag ---- zoom lens cais, thiab rau hauv ib qho kev pom thiab Tom qab ntawd los ntawm lawv cov eyepieces rau hauv daim duab, nws qhov kev nthuav dav hloov pauv los ntawm kev hloov qhov kev ncua deb ntawm pawg iav nruab nrab thiab tau txais, yog li nws tseem hu ua 'zoom stereo microscope' (Zoom-stereo microscope). Nrog rau qhov yuav tsum tau ua ntawm daim ntawv thov, Zoom-lub tso suab microscope tuaj yeem nruab nrog ntau yam khoom siv, xws li fluorescence, kev yees duab, yees duab, lub teeb txias thiab lwm yam.
