00:00 Intro of flat surface creation / polishing
00:37 Optical flatness specs compared to general machining results
01:04 Angular machine / continuous pitch polisher explained
07:24 Simplified version of the continuous pitch polisher
10:15 CNC polishing machine construction explained
11:16 Example of polishing 3 objects flat on a plate
In addition, I discuss my personal method to make flat optics which is a modified / simplified version of the continuous pitch polisher.
This video contains short clips of other videos showing similar continuous pitch polishers in action.

Totally counterintuitive. I've done a fair bit of metalwork sanding and polishing, so I naturally assumed that optical polishing would be similar, only using something harder and flatter to grind the surface. It never occurred to me that the rotational grinding process would use something ductile, yet get better results. Thank you very much for the excellent explanation.

How did I end up watching 12min of "how to polish something to the nm scale?" But you explained it so well that I understood it without any previous experience in polishing glass or anything for that matter

The true test of whether someone has mastered a field is their ability to explain it to the uninitiated in a clear and concise manner, you sir are a credit to the field.

Flat-out the best vid on making flat optical surfaces! Clearly thought out well, I couldn't pitch in any criticism. It's almost like we're on the same wavelength.

This video reminds me of the optician who fell into a lens grinder and made a spectacle of himself.

This is really good, so well detailed. It seems over the years there has been a lot of demonstrations of optical grinding/lapping, lots of "recipes" so to speak, without any detailed explanation as to why it works. I'm coming out of this with a deeper understanding of the process, only took 12 years, but better late than never!

jeez why didnt youtube algorithm recommend this to me earlier??? Its fascinating!!

I have been interested in optical engineering for a long time now and yours is the first channel I have seen that covers it well. So thank you for making such excellent videos.

One of the most clearly explained process ever seen on YouTube. Beautiful. I feel like building one of these now.

I work in the optics industry for a couple of years now and I have to say that your channel is a real treasure! Your videos are both, highly educational and entertaining. Keep up the outstanding work!

Hats off to your narration... I simply was thrilled. I am a retired engineer, 73 yrs.

Very clear and detailed explanation, best I found so far (and no irritating background music).
Cool how you built the turntable from a washing machine motor and rollerblade wheels!

This is the most satisfying and informative presentation I've seen in ages. As a photographer I really appreciate the craftsmanship required to produce high quality optics. My hat off to you Sir! 🎩

Very fascinating seeing someone so specialized and advanced in their field, thank you for sharing.

I've been polishing for a year now. This was super informative. Putting images to techniques helps me understand more of what I do all day long lol

The principle looks simple, its just a tar and turntable, but those who tried working with glass, especially polishing and making it precise, knows that its extremely hard, takes years of practice and patience. Great video.

Excellent vector drawing demonstrating the constant angular velocity.

Fascinating videos, with plenty of details. Thank you for all this useful info and diagrams!

Could watch vids like this all day - thanks for sharing

I've got absolutely no idea why this video was recommended but I'm so glad it was. Fascinating. Well done.
