Kev piav qhia ntawm qhov sib txawv ntawm laser confocal microscope thiab scanning electron microscope
Laser confocal microscope thiab scanning electron microscope yog ob qho tib si point-source scanning imaging, thiab lub magnification yog kho los ntawm kev tswj lub scanning tsav ntau yam. Laser confocal microscope ua haujlwm los ntawm laser scanning thiab tuaj yeem tau txais cov duab peb sab. Scanning electron microscope (SEM) siv ntau lub cev lub cev muaj zog zoo siab los ntawm kev tsom xam electron beam scanning ntawm tus qauv saum npoo los hloov cov duab, thiab tsuas yog ob sab duab tuaj yeem tau txais, tab sis tsis yog peb-dimensional dluab.
1. Cov kev daws teeb meem sib txawv (qhov sib txawv amplification qhov chaw)
Laser confocal: qhov txwv kev daws teeb meem yog 150nm.
Scanning electron microscope: 20nm ~ 0.8nm
2. Txawv scanning tsav hom.
Laser confocal: lub laser rotating daim iav tswj lub laser scanning ntau thiab scanning ceev.
Scanning electron microscope: electromagnetic coil tswj cov scanning ntau thiab scanning ceev ntawm electron beam.
3. Stereo duab txawv
Laser confocal: cov qauv yog cov duab txheej los ntawm txheej hauv Z-axis kev taw qhia los ntawm nano-precision stepping motor, thiab cov software tsim cov duab teeb tsa ntawm txhua txheej rau hauv daim duab peb sab.
Scanning electron microscope (SEM): Ib-thooj duab muaj qhov tob ntawm daim teb thiab belongs rau ob-dimensional duab.
4, daim ntawv thov Scope yog txawv
Laser confocal: ob peb zaug mus rau ntau txhiab zaus
Scanning electron microscope: ob peb zaug mus rau ntau pua txhiab zaus
5. Qhov chaw ua haujlwm sib txawv
Laser confocal: Nws tuaj yeem kuaj cov qauv hauv ib puag ncig atmospheric.
Scanning electron microscope: kuaj cov qauv hauv lub tshuab nqus tsev siab.
