Vim li cas ho tsis tau electron microscope hloov optical microscope?
Electron microscopes siv lub hauv paus ntsiab lus ntawm electron optics, hloov cov kab teeb thiab kho qhov muag nrog cov kab hluav taws xob thiab cov lo ntsiab 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 nyuaj rau kev soj ntsuam cov kab mob uas muaj sia nyob vim lawv xav tau ua haujlwm hauv lub tshuab nqus tsev, thiab irradiation ntawm cov kab hluav taws xob tuaj yeem ua rau hluav taws xob puas tsuaj rau cov qauv lom neeg. 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:
1. Electron microscopes yog ua raws li cov khoom siv kho qhov muag thiab ntxiv cov khoom siv xws li CCD, cov ntxaij vab tshaus, lossis cov khoos phis tawj. Qhov no tsuas yog piav qhia raws li lub tshuab tsom iav video, qhov twg CCD hloov lub qhov muag ntawm tib neeg thoob plaws tag nrho cov txheej txheem duab. Vim hais tias nyob rau hauv kev yees duab imaging, hluav taws xob magnification belongs rau virtual magnification, thiab nyob rau hauv cov nqe lus ntawm pixels, photosensitive los, thiab lwm yam, nws txawv ntau dhau ntawm tib neeg lub qhov muag, yog li nws txawv ntau dhau los ntawm qhov pom ntawm lub tshuab tsom iav;
2. Lwm qhov laj thawj tseem ceeb yog tias CCD belongs rau cov duab kos duab, thaum tib neeg lub qhov muag, tshwj xeeb tshaj yog nyob rau hauv kev soj ntsuam binocular, ua rau muaj kev nkag siab zoo ntawm peb seem. Qhov no yog vim li cas vim li cas qhov tob ntawm thaj tsam ntawm ob qhov loj heev piv;
3. Electron microscopes feem ntau yog sawv cev los ntawm electron scanning 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.
