Physics: Optics- Thick Lenses (1 of 56) The Principal Plane

In this video I will explain the differences between the thick and thin lens, and what are primary and secondary principal planes, and first and second (or back) focal points.

Next video in this series can be seen at:

You have helped me in my first year courses all the way to my fourth year courses!! I am so appreciative of your channel

[agstechnicalsupport]

Thank you for the clear explanation of principal planes and focal points in thin and thick lenses.

[-thesmartboard]

you're the best at explaining stuff

[MyWorld-sxtq]

Finally it's here!
Thank you very much, Professor Biezen.

[sayenshin]

A very good explanation of the principal planes, at last! Thank you!

[thomaschin]

This professor's videos are all so good, really appreciate it!

Nice explanation professor.... From India🇮🇳

i am trying to create a simple lens geometry using CAD
the only formula i used is Snell's formula, using equation in Solidworks i created the refracted light path. also using MathCAD the numbers checked out to 8 decimals with Solidworks.
even with the simplest geometry a plano convex lens, when i draw 2 parallel lines going thru the flat surface and exiting thru the spherical one, the 2 refracted lights do not converge on the principal axis.
i wish there is an easier way to describe it, however all studies assume all parallel rays to central axis go to the focal point. when i build it geometrically using Snell's law i found out this is not the case. i double checked all the geometries and used all kind of relations to no avail.
any help would be appreciated

Thank you sir to clear concept of image formation.

Thank you so much for your videos on this. I have a plano convex thick lens that is 2in thick with a .75 r lens. the flat side rests on a surface and the lens side faces the eye. I am trying to figure out the amount that the image is enlarged at a specific point.

Your videos are fantastic. Thanks very much for your great work. I have a question regarding a lighting system. I am using an LED as my light source, and a plano convex lens and Fresnel lens for distributing light on detector. Unfortunately, there is a shift of illumination area from center of detector because of tolerances of system. I wanted to ask how can I shift the principal plane of system forward in order to increase distribution area? Your help is appreciated in advance.

Thank you sir!! Also, sir, do you plan on doing tensors and L'egendre polynomial/diff eqn, spherical harmonics and Green Functions?? Thank you.

[rbsrana]

Thanku so much sir ...it's really helping ..

Please set your microphone not to switch off recording when there's no voice sound. It's very intrusive. Thank you for your work!

ياريت تخلون ترجمه عربي لان هيج مواهيج دا ندرسها ومجاي افهم كلش طلب هاذ ياريت تنفذونه عل مقاطع وتحطون الهن ترجمه

Sir, why you deleted lecture # (28 of 56) ?

[CarlyDayDay]

It says (1 of 56) but there are only 27 videos in the playlist... This inconsistency frightens and confuses me.
