- Scanning electron microscope principle working - This microscopy lecture is going to explain the Scanning electron microscopy principle and working in details. Scanning electron microscope is widely utilized in the imaging of small specimens. Scanning electron microscopy is a type of light microscopy that is used to visualize biological samples. This video explains the following topics in detail:
1. Scanning electron microscopy principle
2. Scanning electron microscopy working
3. Scanning electron microscope structure and set up
4. Scanning electron microscope principle and working
5. Scanning electron microscope uses
6. Applications of Scanning electron microscopy.
Scanning electron microscope is widely used to get a detailed 3d image of the specimen utilizing electron scattering energy to scan 3d sample surface.
So, if you want to know more about the Scanning electron microscope and Scanning electron microscopy techniques working principle in detail, stay tuned to this microscopy lecture.
Thank you for watching Scanning electron microscopy tutorial.

I have watched all your videos related to bioinformatics and these are very informative and helpful. I have a request if you can make tutorial video on protein docking and next generation sequencing data analysis. Please please......
Okay. Even new bio informatics videos are about to come
We are proud of you.
I also bengali.
Thank you. Glad you liked my lectures
Any engg students ?🤭
Yes
bhaii fatti padi h ,kuch nahi padha
exam ko bss 8 ghnte bachche h bhai 🥹🥹🥹😭😭😭
Bro kaisa Gaya Exam ?@@playerman5896
Same here bro 8 ghante me sem 2@@playerman5896

Sir in SEM structure object should be after the sample then detector ...detect the image what type of 3D structure it have 🤔🤔 you drow before it .. something wrong or not
I got it .... Andoe is present in SEM
😻

What’s the purpose of scan coil used in SEM?
Very nice
Thank you
i like your video

Thanks sir🙏
You're welcome
Hello sir, your lecture is good but can you also use sub titles for your explanation
You can turn auto subtitles in TH-cam
Sir, why don't we use anode in TEM while we are using it in SEM ? Doesn't TEM needs electrons travel in a single beam?? Pls answer sir...
One question is SEM the lenses should be use a magnetic lenses please answer my question
in this technique we are going to use vaccum ?
excuse me sir i have a doubt you mentioned here that anode is a positive charge but anode is usually found to be as negatively charged right?
No cathode is negatively charged
Tq sir
You're welcome
Great..
You're welcome
What is the use of a scan coil? and in transmission electron microscopy, You said that the denser particles are passing and absorbing more energy and lighter particles absorb less energy. why there is less escape in the cleft region of the specimen and why there is more escape in the dense region of the specimen. and in scanning electron microscope does the condenser lenses are made up of glass or EML?
make a video on SEM sample preparation
What is the use of scan coil
In the previous video you've named Objective lens as backscattered eletron detector in SEM
Nice
You're welcome
whats the function of the Scan coils?
and also why do we use ANODE only in SEM and not in or rarely in TEM. Because both require s ingle beam of electron right? Please solve my doubts :/
What is the use of sceam coil sir..
sir why doesnt the anode attracts all the electons to itself and how do they pass through it?
Howmuch resolution is used for a sample??the SEM analysis is only used for detecting the components present in the sample or what?? please say clearly why SEM analysis is important?
Why is electron escape more at bumps and less at clefts?
