Polarizing microscopy

[@dr.amygdalasjoruney4031]

Good evening. I am a MD pathology student in India and this question was asked in one of the states in the final year MD exam last month(long question). None of the pathology books have mentioned about this microscope in detail and our professor has asked us to make notes on it and i am thankful for making in depth video about it. Although this is a very old video, it is still so useful. Appreciate your efforts. Good day.

Thank you so much for appreciating my efforts

Rajesh Koothrapali, is that you?

when the plane polarized light comes out after interacting with the anisotropic specimen it splits into O ray and E ray, not electric and magnetic. Only the Electric vector is considered which gets splits into O and E rays.

Its Excellent... now i Understand.......Thank you so much for your outstanding lecture....

[@Diana-ts5sn]

Thank you so much for your explanation, it was really helpful!

[@shomusbiologyofficial]

You're welcome. Glad to hear that you're getting benefit from my lectures

[@dotheneedful55]

God bless you. This le ture was a life saver.

[@shomusbiologyofficial]

Thank you so much for appreciating my efforts

[@chhayarajawat1377]

Very well explanation...

[@shomusbiologyofficial]

Thank you

After the interaction with the sample we are getting the ordinary (O) & extraordinary ray (E) which are in planes perpendicular to each other, analyzer can allow the light of only one plane then how come in the image we are seeing the interference of both O & E ray though they are in different planes???

Thanks for making this so easy to understand

Plz make a vedio on white board with drawing about the role polarizing microscopy in gout arthritis. If possible make in hindi

If the density is inconsistent, then why do we bother using linearly polarised light? Why wouldn't unpolarised work?

[@masturdebat0r]

+RJK The simple answer is that "isotropic" and "anisotropic" are adjectives that do not correspond to a crystal's density, but rather to its atomic structure. A crystal with isotropic structure will allow light to pass through it at the same speed in every direction. A crystal with anistropic structure will permit light through it at various speeds depending on the direction at which the light enters the crystal. This is why you must use polarized light, not because the substances have different densities. I believe the author of this video was a little confused or didn't phrase the explanation correctly.

[@vidarahmatnejad394]

thank you! it was so easy to follow. I'd appreciate if you let me know if there is any size limit? (I have a spherical sample which has a diameter about 500 microns). Also I'd like to know if there is any specific preparation process for polarized microscopy?(my sample is a bundle of fibers and cells).

[@kanugulatejasri369]

thankyou so much sir

[@shomusbiologyofficial]

You're welcome

Nacl is cubic and isotropic...it will be dark.

stop repeating the same thing again and again...its irritating!!

[@ShaonaBose]

NaCl is not anisotropic and there is no question of magnetic component in the visible part of light.

okay gize...ve must observe vy ve call it micro scopee. Ven it is called Mi -Cross- co-pee and NOT micro SCO PEE. Please, vat do ve meen by microscopee? Ve meen ve have little ...no, excuse m e pleeze.
