Very cool. I have a couple soviet era optical flats. Ive literally have used them at work once. But when i busted them out with my homebuilt flashlight to check just 2 features that were in question my boss was trying to go from customer is always right and you ducked up to then saying well i should have known by your confidence in your voice that you had a way to check them right. The customer who was there was like my sales engineer insists its not right. Turns out he was using what it "felt like". Whats funny is that that was the first time and only time ive used them as in i never checked the parts originally with the flats. Best 60 bucks ive spent on random metrology tools. Watching your bosses face react in real time priceless.
Gday mate I want to purchase an optical flat for checking flatness for parts in my home shop. Can you tell me any places that sell optical flats for a reasonable price. Thanks
This is controlled by the squareness or perpendicularity of the spherometer ring. The bore that locates the dial gauges needs to be machine true to the ring that locates the balls (if it is that type of ring) or the edge of the ring if a solid type. Both perpendicularity and concentricity are important especially if a radius is being measured.
Great video. If there's this much information in all of them, I'll be here for every upload. Happy to have stumbled across this little gem.

Ha ha, nice. Yep, fringes don’t lie.
I watched the entire video but it still seems like magic.
It is. Optical magic! 🪄 😎
Awesome... Comment for the sake of a comment
Thanks for watching and for commenting 😀

is perpendicularity of the probe to 3 ball defined surface critical?and how do u ensure it
