Highly efficient, 500 lines per millimeter, single axis holographic diffraction grating lenses separate light from any source into its spectral components for study and analysis. Recommended for use with our Power Supply and Spectrum Gas Tubes.

Rainbow Symphony glasses are affordable, and a great tool for introducing the concepts of spectroscopy to students. Rainbow Symphony also sells many other products that will help in such education. This time I was especially surprised to discover that they'd added a surprise gift to the order - and appreciated that.Highly recommended.

Worked fine for diffraction grating lab activity. Students always get a kick out of seeing rainbows...and emission Spectra lines.

I use these for spectroscopy demonstrations. The diffraction grating glasses split the light wavelengths into their constituent parts so it's easy to determine which "colors" are being emitted by the light source.These are "linear" meaning you'll get one axis. There are versions of these that create multiple axes (and that looks really cool... but not as useful for teaching purposes.)I buy these in bulk from time to time since they are basically give-aways. Buying in small quantities is too expensive when you're giving one away to each audience member.

Bought quite a few for classroom use to see spectra lines from atomic lamps. Cannot do measurements, but that was not import for the demonstrations.

Excellent solution for crowds, so I don't have to leave my spectral tubes "on" for a long time, that diminishes its useful life.Really good grating, separating spectral lines quite well. Just to clarify, they are not black with a thin gap in the middle, they are transparent clear plastic. Before you hand out to crows, tell them DO NOT TOUCH THE PASTIC! Be very emphatic, because that's the first think they will do anyway :P

I'm a college student and when I took chemistry, we got to work with diffraction grating glasses. They were so cool that I decided to buy some for myself. I bought this pack so I could share the excitement with friends and family. They came in a long tube. The price is right and so far, everyone I've given some to has loved them. Well worth it!

Kids love em! Couldn't keep them away once the kids knew what they were.
