These glasses are super fun and were the perfect "schwag bag" item for our demo on the chemical and physical origins of color in nature. I particularly appreciated the excellent customer service as well! Thanks so much!
Works well
So many times the main comment it "so lovely, but can we take the rainbow glasses home?" For the next 1000 visitors, I can say yes. We look at several elements as well as continuous spectra, so the fact that they are NOT a party rainbow star, but a single line is a real requirement.
Rainbow symphony has been pretty darn consistent in selling high quality rainbow glasses and diffraction gratings. I've been shopping with them for over a decade for our physics labs, and have not been disappointed.
