Watch it come to life
Our Holographic Diffraction Gratings are highly efficient embossed Holographic Optical Elements (H.O.E.). Diffraction Gratings are used for the direct viewing and analysis of spectra from different gas tubes and other light sources. The quality of the spectrum produced from our gratings is the brightest possible with a minimum of distracting visual noise. Our gratings are the principal component in a spectroscope and are used for experiments pertaining to the study of light and color. Project a spectrum using an overhead projector or 35mm slide projector for spectrum demonstration purposes. Use in conjunction with colored film gels for additive and subtractive color demonstrations. Recommended for use with our Power Supply and Spectrum Gas Tubes.

It is a great product to discuss and demonstrate light and its components.
Received it a lot faster than I expected. Good size grating, plenty of it, for pretty cheap. For $30, I got enough grating for all of my students to make a personal spectroscope every semester for the next 10 years. Pretty good.
I love these sheets! I bought them to put in a sunny window, some planned art projects, and to share them with friends! The quality is impeccable. I think if you want diffraction grating for any purpose, this will be a solid buy for you. You get a lot for the cost!! I used a 1x6 inch strip in a south facing window, and at certain times of day it shoots rainbows clear across the room!
They arrived in perfect condition, fast shipping!
I do recommend wearing gloves or finger coverings of some kind while handling so the oil from your hands doesn't get on the sheets
