This wasn't quite what I was looking for. I was looking for a way to lens the magnetic field itself. But this was a fascinating watch. Thank you, I learned a lot. I would also be interested in learning how the deflectors and stigmators are tuned on actual electron microscopes. My understanding is that the old models were analog lacking computer systems, so I wonder how that worked.
Great explanations! One question: why doesn't the bottom of the lens cause the paths to diverge? Why do they continue to converge? I have never found a good explanation for that, and here it seems a bit glossed over. Anyone?
It differs from system to system. Typically hi-end systems have more optical components than low end systems. There is no easy answer for your question.
This video changed my life and how I understand light an electrons, thank you so much!
That was an awesome lecture! I rarely comment but wow. Thank you!

Thank you so much for making this video... it is amazing!
This lecture made my school's optical physics concept more interesting.
Thank you very much! Very useful lectures for me beginners!!! Thx!!!!!!
Wow! This is what i was looking for. Thank you sir for making this video.
Absolutely love it! Thank you
ICON
Great explanation..thank you for your teaching videos. Essential method.
Is there a feedback loop between the coil and the stigmator to reduce the stigmatism? If yes, can you elaborate a little on it?
Great Lectures!!
Thank you for the beautiful explanations Sir!
Great!
Amazing video, very well spoken
Thank you, very good lecture!
Excellent!
Why we cannot use deflector as EM lens? It looks like it also focus the wave
Thank you professor
super explanations, thanks!!
Great Lecture
Thank you very much
magnetic lens was very helpful for me thank you sir
thanks. that was beneficial...
very good
In electromagnetic lens we used current . If we use voltage what will happen sir ??? Is that not produce magnetic field ?? please tell sir
Any one know about that how many lens are used in transmission of electron microscopy
