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: https://www.sydor.com/ Check out their company video at:    • Sydor Optics (Overview)   Clip at 1:20 taken from Gijs Loning's video (OpPad) on his visit to the Zeiss Factory:    • Zeiss   (very nice and informative video, Dutch spoken)
