Why lenses can't make perfect images

This video introduces optical design and optical aberrations. We also assemble a custom 5x microscopy objective that has diffraction-limited performances from Thorlabs stock elements.

I teach this at a university and have designed optical system and lens combinations. Everything said here is very accurate. Thanks for such a great explanation.

I am an ophthalmologist, refractive surgeon. I have been reading a lot, and this is the first time i have got the "coma" aberration. Thanks a lot👏👏👏

[HaiValPal]

by far the best explanation of aberrations i have seen yet! thank you so much!

[yoelbeche]

This is one of the best explanation i've seen so far about lenses

[acpres]

Thanks for the great video! I was searching to understand photography lenses a bit better (elements and aberrations) and this was very very helpful, clearly presented and well explained, thank you!

[QuintinMassey]

Wow, great video. Thank you for going full circle with it all. You helped solidify some unknowns I had in my thinking. Thank you again 🙏

[perspectivex]

nice succinct overview of the aberrations and leaves me feeling like I understand it (which I doubt I really do :))

[cwbh]

This is an awesome video full of explanation. Thanks so much!

[thiagoc.]

Absolutely amazing. Thank you very much for sharing this!

[Christophe_L]

Amazing explanations, things are starting to click now. Thanks!

[ucsdncmir]

Combined good theory explanation and hands on experiment. Super!!!

Spherical aberration comes from the difference between a parabola, which is the correct shape, and a spherical lens which is much easier to manufacture. Spheres are so much easier to make that we just accept the aberration and compensate for it instead of making the right shape to begin with. Right?

Do you give private guidance? Paid of course.

I need to select a lens for 3D reconstruction in an artificial vision system using "Depth from Focus", and your video helped me a lot.

I learned more with this video than reading manuals from Edmund Optics, Keyence, Dr. Schenk and self-called specialists.

It's excellent video to understand optical design.

It would be much easier to understand what the speaker is saying if the video had no music playing in the background.
Thank you.

[strawhatsam]

Thanks for summarizing all the major types of aberrations! This helps me know what to look out for as I design my own lens. Do you have any resources on wide angle camera lenses you know of?

[LiveseyMD]

Thanks for the video, it gives a good basic knowledge about optical design.

[ybalaji]

big thanks for this video.Please make videos on fundamentals for beginners. thank you once again.

[ПавелБережной-цг]

Absolutely amazing! Thank you for this job. It help me a lot

If round glass bends light why can’t you just use a flat square piece of glass at the front to start with? The sensor is also flat and square? Would that help make lenses smaller?

ty for the video, it was nice and educational.
Just one point, you have beautiful accent, which is fine to ear, but some words were hard to understand, where the accent went too rich, to to clear hard words in future.
