Phase contrast microscope 

You explained it in less than 3 minutes and my professor can't explain it in 50 minutes

Your concise & brief presentations are something every RU-vidr should learn from!

So in summary, phase-contrast microscopy is used to see the phase changes in living bacteria. There is a dark side and a light side. The dark side is where the light has absorbed and the light side is where the light has been refracted......

Best video playlist ever.. It's so good can't thank you enough

I search many videos to understand phase contrast microscopy. Only this video give best understanding. Amazing

Concise and crystal-clear, sir! Thank you very much:D

well the background music is really great for study ,

I finally get it now.... Thanks a lot!! Great explanation

Thanks a million sir, this clip is actually helpfull

Your grateful.......congrats it was never exist like this ,,short and clear......please give more others

Excellent explanation as to how the various parts work together. Great job!

Good explanation. Useful video. Keep rocking

Thank you soooo much you've saved my life, your videos are tooo good and covers everything appropriately keep making such videos............ God bless you👍❤

In my world this is a completely normal light microscopy technique..

Great work.well understood

Es ist nicht wahr, dass man Unterschiede im Brechungsindex in der Hellfeldmikroskopie nicht sieht oder darstellen kann. Dazu muss man lediglich den Einfallswinkel des Beleugtungsstrahls entsprechend veraendern. Ich sehe wenig Unterschiede von Phasenkontrast zu einer Kombination aus Hellfeld, Dunkelfeld und Schraegbeleuchtung die den extremen nicht gerechtfertigten finanziellen, apperativen und Einstellaufwand zumindest fuer den Amateurmikroskopiker rechtfertigen wuerden, auch wenn man gebraucht kauft. Unterschiede im Brechungindex von Objekten lassen sich durch variable schraege Beleuchtung im Hobbybereich genuegend befriedigend darstellen. Ich habe auch nie verstanden warum es nicht moeglich ist den Phasenring ausserhalb von Objetiven zu plazieren. Auch der Phasenkontrastkondensor besteht ja nur aus Ringblenden die man selbst anfertigen und einlegen kann. Die 1000 Euro sollte man lieber in einer guten Beleuchtung, Kondensor, Objektiven und Okularen anlegen.

You just explained me 3min but my professor wasn't able to explain me in 40 min lecture lol

Extremely helpful. Many thanks

Great video with clear explanations. Thanks to you, I finally get it now!

thanks a lot sir, this video is so helpful

kanka sağ ol ya mikroskoplardan nefret etmemi azalttın biraz

How many time image is magnified in phase contrast microscope??

U got a new subscribe

شكرا لك من العرب❤

Really explained well. 100%

Hey man thanks for this video

great video

Thanks a ton!! ❤️

I was called by HOD and appriciated for the presentation, I just copied this whole😛🤣
