Qhov txawv ntawm laser confocal microscopy thiab scanning electron microscopy
Ob lub laser confocal microscopy thiab scanning electron microscopy yog point source scanning imaging, uas kho qhov magnification los ntawm kev tswj lub scanning tsav ntau yam. Laser confocal microscopy ua haujlwm los ntawm laser scanning thiab tuaj yeem tau txais cov duab peb sab. Scanning electron microscopy siv ntau lub cev lub cev qhia tau zoo siab los ntawm lub teeb pom kev zoo ntawm electron beam thaum luam theej duab ntawm tus qauv los hloov cov duab. Nws tsuas tuaj yeem tau txais cov duab ob sab, tsis yog duab peb sab.
1. Cov kev daws teeb meem sib txawv (qhov sib txawv amplified qhov chaw)
Laser confocal: qhov kawg daws teeb meem 150nm
Scanning electron microscopy: 20nm ~ 0.8nm
2. Txawv scanning txoj kev tsav tsheb
Laser confocal: Laser rotating daim iav tswj laser scanning ntau thiab scanning ceev
Scanning electron microscope: electromagnetic coil tswj cov scanning ntau thiab scanning ceev ntawm electron beam
3. Cov duab stereoscopic txawv
Laser confocal: Cov qauv yog tsav los ntawm nano precision stepper lub cev muaj zog rau cov duab txheej los ntawm txheej hauv Z-axis kev taw qhia, thiab cov software tsim cov duab teeb tsa ntawm txhua txheej rau hauv cov duab peb-dimensional stereoscopic.
Scanning electron microscopy: Ib daim duab ib leeg muaj qhov tob ntawm qhov loj thiab yog nyob rau hauv daim duab ob sab
4. Ntau qhov kev thov sib txawv
Laser confocal: ob peb mus rau ntau txhiab zaus
Scanning electron microscopy: ob peb zaug mus rau ntau pua txhiab zaus
5. Qhov chaw ua haujlwm sib txawv
Laser confocal: muaj peev xwm kuaj cov qauv hauv cov huab cua puag ncig
Scanning electron microscopy: kuaj cov qauv hauv lub tshuab nqus tsev siab
