Huygens Optics | Foucault movie of a parabolic mirror F/4.2 (200 micron movement steps, very short video) @HuygensOptics | Uploaded March 2011 | Updated October 2024, 1 hour ago.
This is a video that consists of the Foucault images of the first telescope mirror that I made. It has a diameter of 10" (255mm). The mirror is an F/4.2 and the distance steps between the image frames are 0.2mm.
