Dab tsi yog qhov txawv ntawm lub teeb thiab electron microscopes?
Optical microscope thiab electron microscope yog ob hom kev tsom xam, nrog qhov sib txawv ntawm kev txhais, kev faib tawm, thiab muaj pes tsawg leeg.
1. Cov ntsiab lus txawv
Optical Microscope (OM) yog ib qho cuab yeej kho qhov muag uas siv cov qauv kho qhov muag kom nthuav dav thiab duab cov khoom me me uas tsis tuaj yeem ua qhov txawv ntawm tib neeg lub qhov muag, txhawm rau rho tawm cov ntaub ntawv microstructural.
Daim ntawv thov ntawm electron microscopy technology yog raws li lub hauv paus ntawm optical microscopy. Qhov kev daws teeb meem ntawm optical microscopy yog {{0}}}.2 μ m, thiab qhov kev daws teeb meem ntawm kev xa hluav taws xob microscopy yog 0.2 nm, uas txhais tau hais tias kev xa hluav taws xob microscopy nthuav dav 1000 npaug ntawm lub hauv paus ntawm optical microscopy.
2. Kev faib tawm txawv
Muaj ntau txoj hauv kev rau kev siv tshuaj kho qhov muag, uas tuaj yeem muab faib ua peb hom raws li tus naj npawb ntawm eyepieces siv: binocular, thiab monocular microscopes; Raws li seb daim duab puas muaj kev nkag siab ntawm stereoscopy, nws tuaj yeem muab faib ua lub tso suab tsis pom kev thiab tsis pom lub tso suab microscopes; Raws li cov khoom pom, nws tuaj yeem muab faib ua cov khoom siv roj ntsha thiab metallographic microscopes, thiab lwm yam; Raws li cov txheej txheem kho qhov muag, nws tuaj yeem muab faib ua polarization, theem sib piv, thiab qhov sib txawv cuam tshuam qhov sib txawv ntawm microscopy.
Electron microscopes tuaj yeem muab faib ua kis tau tus mob electron microscopes, scanning electron microscopes, reflection electron microscopes, thiab emission electron microscopes raws li lawv cov qauv thiab lub hom phiaj.
3. Cov qauv sib txawv
Lub tshuab kho qhov muag ntawm lub tshuab tsom iav feem ntau suav nrog plaub yam: lub hom phiaj lens, lub qhov muag pom, lub teeb pom kev, thiab lub condenser. Kev hais lus dav dav, nws kuj suav nrog qhov chaw teeb pom kev zoo, cov ntxaij lim dej, cov ntawv npog, thiab cov iav slides.
Lub tshuab ntsuas hluav taws xob muaj peb ntu: lub raj, lub tshuab nqus tsev, thiab lub txee fais fab
