Dab tsi yog qhov txawv ntawm Scanning Electron Microscope thiab Optical Microscope
1. Cov ntsiab lus sib txawv:
Optical microscope yog ib qho cuab yeej kho qhov muag uas siv cov ntsiab lus kho qhov muag kom nthuav dav thiab duab cov khoom me me uas tsis tuaj yeem txawv ntawm tib neeg lub qhov muag, kom tib neeg tuaj yeem rho tawm cov ntaub ntawv microstructure.
Daim ntawv thov ntawm tag nrho automatic scanning electron microscopy thev naus laus zis yog ua raws li lub tshuab ntsuas qhov muag. 1000x magnification.
2. Ntau pawg:
Optical microscopes muaj ntau hom kev faib tawm, uas tuaj yeem muab faib ua trinocular, binocular thiab monocular microscopes raws li tus naj npawb ntawm eyepieces siv; stereoscopic thiab non-stereoscopic microscopes yuav muab faib ua stereoscopic thiab non-stereoscopic microscopes raws li seb daim duab yog stereoscopic; Biological thiab metallographic microscopes, thiab lwm yam.; tuaj yeem muab faib ua lub teeb polarized, theem sib piv thiab qhov sib txawv cuam tshuam qhov sib txawv ntawm lub tshuab tsom iav raws li cov qauv kho qhov muag.
Tsis siv neeg scanning electron microscopes yuav muab faib ua kis tau tus mob electron microscopes, scanning electron microscopes, reflection electron microscopes thiab emission electron microscopes raws li lawv cov qauv thiab siv.
3. Cov qauv tsim muaj qhov sib txawv:
Lub tshuab kho qhov muag ntawm lub tshuab tsom iav feem ntau suav nrog plaub ntu: lub hom phiaj lens, eyepiece, reflector thiab condenser. Hais lus dav dav, nws kuj suav nrog qhov chaw teeb pom kev zoo, cov ntxaij lim dej, cov ntawv npog thiab cov swb.
Lub tshuab ntsuas hluav taws xob tsis siv neeg lub tshuab ntsuas hluav taws xob muaj peb ntu: lub lens raj, lub tshuab nqus tsev thiab lub hwj chim txee.
Piv nrog rau optical microscopes thiab kis electron microscopes, scanning electron microscopes muaj cov yam ntxwv hauv qab no:
1. Cov qauv ntawm cov qauv saum npoo tuaj yeem pom ncaj qha, thiab qhov loj ntawm cov qauv tuaj yeem loj li 120mm × 80mm × 50mm.
2. Cov txheej txheem kev npaj ua qauv yog yooj yim thiab tsis tas yuav txiav rau hauv nyias nyias.
3. Cov qauv tuaj yeem muab txhais thiab tig rau hauv qhov chaw peb sab hauv cov qauv chamber, yog li cov qauv tuaj yeem pom los ntawm ntau lub kaum ntse ntse.
4. Qhov tob ntawm daim teb yog loj, thiab cov duab yog tag nrho ntawm peb-dimensional nyhuv. Qhov tob ntawm thaj chaw ntawm lub tshuab ntsuas hluav taws xob ntsuas hluav taws xob yog ntau pua lub sij hawm loj dua li ntawm lub tshuab ntsuas qhov muag, thiab kaum ob lub sij hawm loj dua li ntawm lub tshuab hluav taws xob xa hluav taws xob.
5. Qhov loj ntawm daim duab yog qhov dav thiab qhov kev daws teeb meem yog qhov siab. Nws tuaj yeem nthuav dav los ntawm kaum zaug mus rau ntau pua txhiab zaus, thiab nws pib suav nrog qhov kev nthuav dav ntawm cov iav tsom iav, tsom iav tsom iav mus rau kev xa hluav taws xob microscope. Qhov kev daws teeb meem yog nruab nrab ntawm lub tshuab kho qhov muag thiab lub tshuab xa hluav taws xob, mus txog 3nm.
6. Kev puas tsuaj thiab paug ntawm cov qauv los ntawm cov kab hluav taws xob yog me me.
7. Thaum soj ntsuam cov morphology, lwm cov cim qhia los ntawm cov qauv kuj tuaj yeem siv rau kev tsom xam cov cheeb tsam ntawm micro.
