How to make Very Flat Optical Surfaces on Glass @HuygensOptics

Huygens Optics | How to make Very Flat Optical Surfaces on Glass @HuygensOptics | Uploaded December 2019 | Updated October 2024, 3 hours ago.
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.

$Wave frequencies passing a grating This video shows a simulation of a transmissive grating on a glass plate that sends different wave frequencies in different angular directions. In the second part it show how it also does this if the incoming wave is a linear sum of 3 different frequencies. Thereby it performs a Fourier transform on the incoming wave signal (time domain) to intensity in an angular direction (a spectrum in the frequency domain) It was reuploaded because the original version contained an annoying error in the frequency indices. The Python code used for the wave simulation can be found on the @DiffractionLimited channel$ $Telescope Resolution vs. Aperture and Wavelength Discussion about of the fundamental limitations imposed by aperture and wavelength on the maximum sharpness of a telescope. By discussing the energy mechanisms behind diffraction, I try to explain why this relationship exists. In the last part I discuss the implications for the recently launched James Webb telescope.
