How to make Very Flat Optical Surfaces on Glass

@huygensopticsAbout
Hi, my name is Jeroen and on the Huygens Optics channel I publish videos on personal projects. My main fields of interest are optics, mechanics and photolithography. The videos aren't targeted towards a general audience but for people with a passion for science and technology (e.g. my fellow nerds). The channel is named after the famous Dutch mathematician, astronomer and inventor Christiaan Huygens (1629-1695). He was the first to publish a mathematical description of the wave properties of light, and also discovered Saturn's rings. I make these videos for fun, without a financial motivation. Please don't contact me for sponsoring contracts or in-video advertisement. Neither me nor my viewers are interested. If you want to contribute as a viewer, you can do so by either donating using the Paypal link or by using the Patreon account: https://www.patreon.com/huygens_optics Your donation helps me to make better videos.

Video Description
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: https://www.youtube.com/watch?v=N3RbCq8Kg5U& Clip at 1:20 taken from Gijs Loning's video (OpPad) on his visit to the Zeiss Factory: https://www.youtube.com/watch?v=9YhsTEOjxtU (very nice and informative video, Dutch spoken)
