Holographic Diffraction Grating Glasses

Rainbow Symphony provides a multitude of tools to help you learn and teach about light and color. Whether you’re looking for gratings, filters, or holographic diffraction grating glasses, check out our selection today to find exactly what you need!

Slides, Peepholes, and Rolls

Our diffraction grating selection comes in three different styles: diffraction grating slides, peepholes, and rolls. Rolls are best used while working on large projects, and slides and peephole gratings are perfect while lecturing or handing out to your class to facilitate personal exploration. Our diffraction gratings are available in single and double axis diffraction.

Holographic Diffraction Grating Glasses

Choose from single or double axis diffraction grating glasses and customize them with your organization’s name, logo, or even custom art backgrounds! We have several pre-made designs including neon colors, multi colors, and animal themed options.

Filters and Tubes

In addition to all our diffraction gratings, we also provide tons of learning accessories such as color filters and paddles, as well as spectrum tubes that emit light due to the variety of gases they contain. Our color gases allow you to see different colors of the spectrum as you look at them through the slides. Choose from tubes that contain helium, argon, hydrogen, neon, mercury vapor, and many more!

Custom Products

When it comes to promoting your business, Rainbow Symphony has multiple options to help you distribute branded merchandise at events, concerts, and trade shows. No matter your industry, you can customize our products with your business logo, name, and additional information to spread the word about your company.
