Cov Cheebtsam tseem ceeb thiab kev ua haujlwm ntawm Laser Scanning Confocal Microscope

 

1. Illumination pinhole
Muaj nuj nqi: Ua kom lub laser hla dhau lub teeb pom kev zoo los tsim lub teeb pom kev zoo, uas muaj qhov zoo xws li kev coj ua muaj zog, me me divergence, siab ci, siab spatial thiab temporal coherence, thiab planar polarization excitation. Thiab nws tsim ib lub confocal ntaus ntawv nrog lub detector pinhole thiab focal dav hlau.

 

2. Beam splitter
Muaj nuj nqi: cais cov qauv excitation fluorescence los ntawm lwm yam tsis teeb liab teeb.

 

3. Lub hom phiaj lens

 

4. Focal dav hlau
Kev Ua Haujlwm: Lub laser point lub teeb tsom rau ntawm qhov khoom ntawm lub dav hlau focal, zoo siab rau fluorescently sau cov qauv kom tawm fluorescence thiab tsim ib qho chaw focal. Lub teeb pom kev zoo yog ua tiav los ntawm cov khoom siv xws li lub hom phiaj lens thiab lub teeb pom kev zoo, thiab tsom mus rau ob qhov chaw: lub teeb pom kev zoo thiab lub teeb pom kev pinhole. Lub ntsiab lus ntawm confocal los ntawm qhov no.

 

5. Ntes pinhole
Muaj nuj nqi: Ua si raws li cov lim dej spatial. * Txhawm rau ua kom muaj kev cuam tshuam loj tshaj plaws ntawm lub dav hlau tsis tsom teeb pom kev tawg thiab tawg lub teeb tawm sab nraum qhov chaw tsis pom kev ntawm lub dav hlau tsom, txhawm rau xyuas kom meej tias tag nrho cov teeb liab fluorescence tau txais los ntawm tus ntes pinhole los ntawm qhov chaw focal ntawm qhov chaw coj mus kuaj. Yog li ntawd, lub diffraction tsom qhov chaw ntawm tus qauv thiab lub ntes pinhole imaging chaw muaj tib cov ntaub ntawv (ob -point conjugate).

 

6. Photomultiplier tube (kwv yees)
Muaj nuj nqi: Tau txais lub teeb liab los ntawm pinholes, hloov mus rau hauv cov teeb liab hluav taws xob, thiab xa mus rau lub computer, uas ua rau pom cov duab meej ntawm tag nrho cov dav hlau focal ntawm lub vijtsam.

 

7. Laser: Txoj kev loj hlob ntawm confocal microscopy technology tsis tuaj yeem sib cais los ntawm kev loj hlob sai ntawm lasers. Peb tuaj yeem xaiv cov lasers sib txawv raws li peb cov kev tshawb fawb xav tau. as ArUV(351.364nm), HeCd(442nm), AR(457,488,514nm), ArKr(488,568,647nm)Kr(568nm),HeNe(543nm),HeNe(633nm) Tos.

 

8. Ntau cov fluorescence channels: Muaj ntau cov fluorescence raws kom ua tiav ntau cov ntawv sau ntawm cov qauv ib txhij.
