Electron microscopy muaj cov qauv cwj pwm yooj yim uas zoo ib yam li optical microscopes, tiam sis nws muaj peev xwm ua kom muaj peev xwm ua kom nrov loj thiab paub qhov txawv dua li cov khoom siv ua qhov muag, uas siv hluav taws xob raws li lub teeb tshiab los ua cov khoom siv. Txij li thaum xyoo 1938, Ruska tau tsim thawj kis hluav taws xob hauv tshuab hluav taws xob, ntxiv rau kev sib txuas ntawm electron microscopy nws tus kheej, kev ua tau zoo ntawm kev txhim kho, tab sis kuj yog kev tsim ntau yam ntawm lwm yam electron microscopy. xws li kuaj tshuab electron microscope, analytical electron microscope, UHV electron microscope thiab li ntawm. Ua ke nrog ntau hom electron microscope qauv kev ua qauv, kev kuaj tau ua tiav nyob rau ntau qhov ntawm tus qauv lossis cov qauv thiab kev sib raug zoo ntawm txoj kev tshawb nrhiav. Cov kab xos yog siv los saib cov dluab ntawm cov khoom me me. Feem ntau siv los soj ntsuam ntawm cov kab mob, cov tshuaj thiab cov tshuaj me me.
Ib qho hluav taws xob tsom hluav taws xob tau ua kom nrov tau ib qho khoom rau 2 vam npaug zaug. Desktop tsom, feem ntau yog hais txog cov tsom iav siab, nws yog lub tshuab ua kom nrov siab, nws cov duab siab yog siab, cov duab zoo dua, tiam sis qhov dav ntim loj, tsis yoojyim txav, siv ntau hauv qhov kev kuaj, tsis zoo los yog tawm ntawm -tseem kuaj.
