How to make Very Flat Optical Surfaces on Glass
The video shows (hands on) how a nanometer level flat optical surface can be made. It first discusses the principle of the continuous pitch polisher, also known as the planetary polisher or optical lap master.
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.
Clips at 1:16min and 5:16 min were displayed by courtesy of Sydor Optics:
