Vim li cas electron microscopes tsis tuaj yeem hloov lub teeb microscopes
Lub tshuab electron siv lub hauv paus ntsiab lus ntawm electron optics, hloov lub teeb beam thiab optical lens nrog ib tug electron beam thiab electron lens, thiaj li hais tias cov qauv zoo ntawm cov khoom yog imaged nyob rau hauv heev magnification. Nws tau zoo dua li qhov kho qhov muag tsom iav, tab sis lub tshuab ntsuas hluav taws xob yuav tsum tau ua haujlwm hauv lub tshuab nqus tsev, yog li nws tsis yooj yim rau kev soj ntsuam cov kab mob nyob, thiab irradiation ntawm electron beam tseem yuav ua rau cov kab mob lom irradiated puas, yog li nws tsis tuaj yeem. tag nrho hloov lub tshuab kho qhov muag, thiab lawv cov nqi tsis zoo ib yam, thiab haum rau ntau yam kev ua haujlwm. Kuv vam tias kuv cov lus teb yuav pab tau koj.
Yog vim li cas vim li cas electron microscope tsis tuaj yeem hloov kho qhov muag microscope yog li hauv qab no:
1. electronic microscope belongs rau optical microscope raws li qhov sib ntxiv ntawm CCD, tso saib lossis khoos phis tawj khoom siv, uas tuaj yeem tsuas yog hais tias yog lub tshuab tsom iav video, tag nrho cov txheej txheem imaging, CCD hloov ntawm tib neeg lub qhov muag. Vim hais tias cov duab yees duab, hluav taws xob magnification yog cuav amplification, thiab nyob rau hauv lub pixel, lub teeb rhiab heev nyhuv thiab lwm yam, nrog rau tib neeg lub qhov muag yog ib tug loj heev sib txawv, yog li ntawd nrog rau qhov pom kev microscope nyhuv yog loj heev sib txawv;
2. Muaj ib qho tseem ceeb tshaj plaws, CCD belongs rau lub dav hlau imaging, thiab tib neeg lub qhov muag, tshwj xeeb tshaj yog kev soj ntsuam binocular, yuav tsim ib tug muaj zog kev txiav txim zoo ntawm peb-dimensional, uas yog ob qhov sib txawv qhov tob ntawm cov nyhuv yog loj heev;
3. Electron microscope feem ntau yog qhia raws li electron scanning microscope, cov nyhuv microscope yuav zoo dua li cov nyhuv ntawm optical microscopy, tab sis vim yog tus nqi siab, yog li ob peb daim ntawv thov thiab kev lag luam.
