Vim li cas ho tsis tau electron microscopes hloov optical microscopes
Lub tshuab ntsuas hluav taws xob siv lub hauv paus ntsiab lus ntawm electron optics, siv cov kab hluav taws xob hluav taws xob thiab cov lo ntsiab muag es tsis txhob siv cov kab teeb ci thiab cov lo ntsiab muag kho qhov muag, kom pom cov qauv zoo ntawm cov teeb meem ntawm qhov loj heev. Txawm hais tias nws qhov kev daws teeb meem yog qhov zoo tshaj plaws ntawm optical microscopes, electron microscopes tsis yooj yim rau kev soj ntsuam cov kab mob uas muaj sia nyob vim lawv xav tau ua haujlwm nyob rau hauv lub tshuab nqus tsev, thiab electron beam irradiation tuaj yeem ua rau hluav taws xob puas tsuaj rau cov qauv lom. Yog li ntawd, lawv tsis tuaj yeem hloov kho qhov muag microscopes, thiab lawv cov nqi thiab kev ua haujlwm tsim nyog kuj txawv. Kuv vam tias kuv cov lus teb yuav pab tau koj.
Cov laj thawj vim li cas electron microscopes tsis tuaj yeem hloov kho qhov muag microscopes yog raws li hauv qab no:
ib
Electron microscopy yog ib qho khoom siv kho qhov muag uas ntxiv cov khoom siv xws li CCD, zaub screen, lossis computer. Nws tsuas tuaj yeem hu ua lub tshuab tsom iav video, thiab thoob plaws hauv cov txheej txheem duab, CCD hloov lub qhov muag ntawm tib neeg. Vim hais tias nyob rau hauv video imaging, hluav taws xob amplification belongs rau virtual amplification, thiab nyob rau hauv cov nqe lus ntawm pixels, photosensitivity, thiab lwm yam, nws txawv ntau dhau los ntawm tib neeg lub qhov muag, yog li nws txawv ntau dhau los ntawm qhov pom kev siv lub tshuab tsom;
2. Lwm qhov laj thawj tseem ceeb yog tias CCD belongs rau cov duab kos duab, thiab tib neeg lub qhov muag, tshwj xeeb tshaj yog nyob rau hauv kev soj ntsuam binocular, ua rau muaj kev nkag siab zoo ntawm stereoscopy, uas yog vim li cas rau qhov tob tob ntawm thaj tsam ntawm ob qho tib si;
3. Electron microscopes feem ntau hu ua scanning electron microscopes, uas muaj txiaj ntsig zoo dua li cov tshuab kho qhov muag dav dav. Txawm li cas los xij, vim lawv cov nqi siab, lawv tsis tshua siv hauv kev lag luam.
