There is no need for users to worry about where to hold the grating or what the orientation should be. The glasses are also larger and more visible than slides and easier to keep track of after the lesson.As implied by the product photos, the spectra are dispersed horizontally (grating rulings vertical), which is most convenient with most lab sources and easy for students to understand. With the relatively coarse 500 lines/mm, both first and second order spectra are visible. [ I also purchased a pack of the 1000 lines/mm glasses Rainbow Symphony Diffraction Grating Glasses - Linear 1000 Line/Millimeters, Package of 50 for studies requiring higher dispersion, but these, alas, turned out to have the gratings oriented differently, with the spectra dispersed vertically.] ### ⭐⭐⭐⭐⭐ Great for educational purposes. They make learning about light fun and educational. *by T***L on June 11, 2018* 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. ### ⭐⭐⭐⭐⭐ Wow *by B***A on July 27, 2019* Great for light spectrums with bulbs and tubes awesome better than a prism anyday --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/174686859-rainbow-symphony-diffraction-grating-glasses-linear-500-line-millimeters-package](https://www.desertcart.in/products/174686859-rainbow-symphony-diffraction-grating-glasses-linear-500-line-millimeters-package) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-04-25*
