Dab tsi yog qhov txawv ntawm optical microscope thiab electron microscope
Optical microscopes thiab electron microscopes yog ob hom microscopes sib txawv. Lawv txawv nyob rau hauv kev txhais, kev faib, thiab muaj pes tsawg leeg.
1. Cov ntsiab lus txawv
Optical microscope (English Optical Microscope, abbreviated as OM) yog ib qho khoom siv kho qhov muag uas siv cov qauv 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 khaws cov ntaub ntawv zoo.
Daim ntawv thov ntawm electron microscopy thev naus laus zis yog ua raws li lub tshuab ntsuas qhov muag. Qhov kev daws teeb meem ntawm lub tshuab ntsuas qhov muag yog {{0}}}.2μm, thiab qhov kev daws teeb meem ntawm lub tshuab hluav taws xob xa hluav taws xob yog 0.2nm. Qhov ntawd yog hais tias, qhov kis tau tus mob electron microscope muaj qhov loj ntawm 1000 ntawm lub hauv paus ntawm optical microscope. sij hawm.
2. Kev faib tawm txawv
Muaj ntau ntau txoj hauv kev rau kev kho qhov muag microscopes. Lawv tuaj yeem muab faib ua trinocular, binocular thiab monocular microscopes raws li tus naj npawb ntawm eyepieces siv; lawv tuaj yeem muab faib ua stereoscopic vision thiab non-stereoscopic vision microscopes raws li seb daim duab puas muaj kev nkag siab peb-dimensional; Lawv tuaj yeem muab faib ua stereoscopic vision thiab non-stereoscopic vision microscopes raws li cov khoom soj ntsuam. Biological thiab metallographic microscopes, thiab lwm yam.; Raws li cov txheej txheem kho qhov muag, lawv tuaj yeem muab faib ua lub teeb polarized, theem sib piv thiab qhov sib txawv cuam tshuam qhov sib txawv ntawm lub tshuab tsom, thiab lwm yam.
Electron microscopes tuaj yeem 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 kev siv.
3. Cov khoom sib txawv thiab cov qauv
Lub tshuab kho qhov muag ntawm lub tshuab tsom iav feem ntau muaj plaub yam: 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, thiab lwm yam.
Lub tshuab ntsuas hluav taws xob muaj peb ntu: lub lens raj, lub tshuab nqus tsev thiab lub hwj chim txee.
