oxtoolco | Russian Optical Flat Testing @oxtoolco | Uploaded October 2017 | Updated October 2024, 1 week ago.
In this video we take a look at a Russian optical flat off ebay. Buying an optical flat used is a little tricky so these are a good option for folks wanting to try this technique. We show you can produce fringes with daylight florescent lamps. We take a look at some different surfaces in the shop and discuss the patterns. We also use a Helium Monochromatic light to show the difference in fringe quality with the proper light source.
