Lub teeb thiab electron microscopes txawv ntawm ib leeg. Sib piv cov kev hloov pauv ntawm cov ntsiab lus zoo sib xws.
Lub tshuab ntsuas qhov muag tsuas tuaj yeem pom cov qauv ntawm tes, xws li cov phab ntsa ntawm tes, chloroplasts, cov ntawv sau chromosomes, mitochondria, nuclei, thiab lwm yam, thaum lub tshuab hluav taws xob hluav taws xob tuaj yeem soj ntsuam tag nrho cov qauv ntawm tes. Txhawm rau muab nws yooj yim, lub teeb pom kev zoo tuaj yeem nthuav tawm cov qauv microscopic ntawm lub xov tooj ntawm tes, thaum lub tshuab ntsuas hluav taws xob tuaj yeem nthuav tawm nws cov submicroscopic muaj pes tsawg leeg.
Qhov magnification yog qhov txawv ntawm qhov tseem ceeb. Txawm hais tias siv ntau npaum li cas zoom, optical microscopes muaj qhov loj tshaj plaws uas tib neeg lub qhov muag tsis pom. y (min)=0.61 * wavelength / (n * sinu) Qhov siab tshaj plaws yog kwv yees li 1.5 txawm tias n * sinu yog submerged hauv roj, thiab cov nyiaj seem nyob ntawm qhov wavelength qhov loj. Yog li ntawd, zooming nyob rau hauv yog tsis muaj dab tsi vim hais tias qhov siab tshaj plaws magnification ntawm lub optical microscope yog nyob ib ncig ntawm 1000 lub sij hawm. Txij li lub wavelength ntawm cov kab hluav taws xob siv nyob rau hauv electron microscope imaging yog luv dua li qhov pom lub teeb, lawv tuaj yeem daws cov ntsiab lus me me, tso cai rau kev nthuav dav txog li ob peb lab.
