These pics are a continuation of what I did last week. I used two of the same rainbows consisting of a 405, 445, 520, 589, & for the reds, a 638 and a 650 nm's. I configured the 4 mirrors exactly the same as I did last week. The difference this time was I reflected all 10 beams into fan diffraction grating creating many, many beams. The first two pics were not using diffraction gratings. Also on some of them I also used a 473nm in the center into different reflective diffraction gratings. The last sequence of photos were of trying to get a decent rainbow from the diffraction gratings that came out pretty good. Enjoy.
